why was the of rate of co2 per minute so low for 1% galactose when compared to 1% glucose?

Answers

Because yeast needs nearly an hour to reach the stage of utilising galactose, whereas glucose occurs immediately, the rate of CO2 per minute for 1% galactose was much lower than that for 1% glucose.

Although yeast and galactose can substitute glucose, it is usually the substrate for anaerobic respiration. Glucose's isomer is galactose. Only their atoms' arrangement is different between them. Stereoisomers of each other exist between glucose and galactose. The hydroxyl group's (OH) orientation at carbon 4 is the primary structural variation between galactose and glucose. As a result of the seedlings' photosynthesis, which uses up CO2, less CO2 is being measured.

the characteristics of an organism are rooted in the activities of cellular encoded by genes.

Answers

It is TRUE that the characteristics of an organism are rooted in the activities of cells, which are in turn encoded by genes.

Genes are sections of DNA that contain instructions for making proteins, which serve as the skeleton of cells. Gene expression and protein synthesis are influenced by a variety of variables that control the activity of genes, including internal signaling pathways and external signals. The interactions between several genes and their byproducts, as well as different environmental conditions, result in complicated biochemical processes that drive cellular activities. The morphology, physiology, behavior, and reaction to the environment of the cell and the organism as a whole are all determined by these processes.

The properties of the organism can vary as a result of changes in cellular activities brought on by changes in the genetic code, such as mutations or changes in gene expression. As a result, an organism's traits are dictated by the actions of its cells, which are governed by the genes that are encoded in its DNA.

Concentric contractions occur when
A. the muscle produces increasing tension as it shortens.
B. the tension and length of the muscle remain constant during a contraction.
C. tension in a muscle is maintained while the muscle increases in length.
D. the muscle produces tension while the length of the muscle increases.
E. isometric contractions occur.

Answers

Concentric contractions occur when the muscle produces increasing tension as it shortens. Thus, the correct option will be A.

What are Concentric Contractions?

Concentric contraction is the shortening of the muscles while the tension remains the same. The tension is produced when the fibers of the muscles pull together, which results in shortening the muscle. An example of a concentric contraction is the upward motion in a bicep curl, and it is also referred to as a positive contraction. This means that the muscle is contracting while shortening.

When the muscle shortens, the distance between the muscle’s origin and insertion points decreases. This creates a movement around a joint, which is known as concentric motion. This type of contraction also occurs when you lift weights. Lifting weights involves the shortening of muscles around the joints to raise the weight. When you perform bicep curls, the muscles in the bicep shorten, allowing you to lift the weight.

What is feedback regulation of endocrine system?

Answers

To ensure that these processes are properly regulated, the endocrine system employs a feedback mechanism to regulate hormone levels.

What is Feedback regulation?

Feedback regulation is the process by which hormone levels are regulated in the endocrine system. Hormones are chemical messengers that travel throughout the body to regulate various physiological processes. This feedback mechanism operates through a series of feedback loops that monitor hormone levels in the blood and adjust hormone secretion accordingly.

Hormones are chemical messengers that are produced by the endocrine glands and secreted into the bloodstream. These hormones travel to target cells in the body, where they bind to specific receptor proteins on the surface of the cell. The binding of a hormone to its receptor triggers a series of signaling pathways within the cell that ultimately lead to changes in gene expression and other cellular processes.

Feedback regulation is critical to maintaining proper hormone levels in the body. When hormone levels become too high or too low, the feedback mechanism responds by adjusting hormone secretion to restore balance. This ensures that the body's physiological processes remain properly regulated and functioning efficiently.

which structure do the calcium ions bind to when muscle contraction is initiated?

Answers

In muscle contraction, calcium ions bind to the regulatory protein troponin, which is part of the thin filament of muscle fibers.

When a nerve impulse reaches a muscle fiber, it triggers the release of calcium ions from the sarcoplasmic reticulum (a specialized type of smooth endoplasmic reticulum) in the muscle cell. The calcium ions then bind to troponin, causing a conformational change in the protein complex that moves tropomyosin away from the myosin-binding sites on the actin filament.

This allows myosin heads to bind to actin and form cross-bridges, initiating the sliding of the actin and myosin filaments past each other, leading to muscle contraction. When the level of calcium ions in the cytosol decreases, troponin returns to its original conformational state, causing tropomyosin to block the myosin-binding sites and preventing further muscle contraction.

Under fasting conditions (ratio of insulin to glucagon <1), elevated glucagon will activate which of the following enzymes?
a. glycogen synthase
b. lipoprotein lipase
c. hormone sensitive lipase
d. pyruvate dehydrogenase complex

Answers

Under fasting conditions (ratio of insulin to glucagon <1), elevated glucagon will activate hormone sensitive lipase enzymes. The correct option is c.

How does the glucagon hormone work in the body?

The hormone glucagon is produced by the pancreas, which aids in regulating glucose levels in the blood. Glucagon is the hormone that raises blood sugar levels in the body. Glucagon stimulates the liver to convert glycogen into glucose, which is then released into the bloodstream. Glucagon causes the liver to break down glycogen into glucose, which is then released into the bloodstream. The liver produces glucose through a process known as gluconeogenesis, which helps to raise blood sugar levels.Insulin is a hormone produced by the pancreas that aids in the absorption of glucose into the body's cells. When insulin levels are low, the hormone glucagon is released to counteract the effects of insulin by raising blood sugar levels in the body.

Hormone-sensitive lipase is an enzyme that aids in the breakdown of stored fat into free fatty acids and glycerol when activated by elevated glucagon levels in the bloodstream. This aids in providing energy for the body when glucose levels are low. When the ratio of insulin to glucagon is less than 1, the hormone-sensitive lipase enzyme is activated, and glycogen synthesis is inhibited. This results in the release of fatty acids from adipose tissue into the bloodstream. This process aids in providing the body with energy during fasting or exercise periods.

mouth-shaped openings in the epidermis of plants are called

Answers

Stomata are the mouth-shaped openings in the epidermis of plants. These tiny pores are surrounded by two specialized guard cells that control the opening and closing of the stomata.

The guard cells are responsible for regulating the exchange of gases and water vapor between the plant and its environment. When the stomata are open, carbon dioxide can enter the plant and oxygen and water vapor can exit. This process, known as transpiration, is essential for plant growth and survival. Stomata are typically found on the leaves of plants, although they can also be found on stems and other parts of the plant. The number and distribution of stomata on a plant can vary depending on the species, environmental conditions, and other factors. In general, plants that live in dry or arid environments tend to have fewer stomata, while those that live in wetter environments tend to have more. Additionally, some plants have specialized stomata that are adapted to specific environmental conditions. For example, certain plants that live in saline environments have evolved stomata that are able to exclude salt from entering the plant.

In what type of axon does saltatory conduction occur?a. myelinatedb. unmyelinated

Answers

Answer: myelinated

Explanation:

Saltatory conduction occurs only on myelinated axons.

Final answer:

Saltatory conduction occurs in myelinated axons. The myelin sheath on these axons promotes faster signal propagation by allowing action potentials to 'jump' from one node of Ranvier to the next.

Explanation:

Saltatory conduction occurs in myelinated axons. Myelinated axons are axons that are covered by a fatty substance known as myelin. This myelin sheath insulates the axon and increases the speed at which electrical impulses, or action potentials, are transmitted along the axon. During saltatory conduction, the action potential 'jumps' from one node of Ranvier to the next. These nodes are the small gaps in the myelin sheath along the axon. Compared to unmyelinated axons, where the action potential propagates in a continuous wave, the 'jumping' action in myelinated axons leads to faster signal propagation.

The neurotransmitter released into the synapse between neurons and muscle cells that stimulate skeletal muscle cell isGABAepinerphrinenorepinephrineacetylcholine

Answers

The neurotransmitter that is released into the synapse between neurons and muscle cells that stimulates skeletal muscle cells is acetylcholine. Here option D is the correct answer.

Acetylcholine is a chemical messenger that is released from the axon terminals of motor neurons and diffuses across the neuromuscular junction to bind to acetylcholine receptors on the surface of skeletal muscle cells.

This binding triggers a series of biochemical reactions that lead to the contraction of the muscle fiber. The release of acetylcholine is essential for normal muscle function, and disruptions in the production or release of this neurotransmitter can lead to muscle weakness or paralysis.
