Order the steps of glycogen synthesis. Not all descriptions accurately describe glycogen synthesis; therefore, not all the descriptions will be used; four of the descriptions will be used in the correct answer.
1.Glucose phosphorylation. The first step in glycogen synthesis is conversion of glucose to G-6-P.
2.Glucose-1-phosphate formation.
3.Glucose activation.
4.Glucose addition to the polymer backbone
Glycogen synthesis starts with UDP-glucose phosphorylase, which combines the nucleotide uridine triphosphate (UTP) with glucose-1-phosphate to launch pyrophosphate (PPi) and form UDP-glucose. The phosphoanhydride change response catalyzed by way of UDP-glucose phosphorylase is minimally exergonic.
Glycogen synthase, as discussed in advance, catalyzes the price-restricting step in glycogen synthesis within the liver and in skeletal muscle, namely, the switch of glucose monomers from UDP-glucose to the terminal branch of the developing glycogen chain thru the formation of α(1→4) glycosidic bonds.
The glucagon signaling pathway is a method of a chain of extended blood glucose enzymatic reactions prompted with the aid of the binding of glucagon that produced by means of pancreatic islets alpha cells to the glucagon receptor on the surface of liver cells.

In a mature human testis, spermatogonia, spermatocytes, spermatids, and sperms should be formed in the proper order during the spermatogenetic process.
Spermatogenesis is the cycle by which haploid spermatozoa are formed. They develop from germ cells. These germ cells develop in the seminiferous tubules of the testis. This cycle begins with the mitotic division of immature microorganisms near the cell layer of the tubules. Thus the primary spermatocyte divides into two haploid daughter cells called secondary spermatocytes. Each secondary spermatocyte now undergoes a second. Each secondary spermatocyte now undergoes a second maturational division that is mitotic. Thus each secondary spermatocyte gives rise to two spermatids that are transformed to form two spermatozoa.

ells require a constant exchange of solutes (ions and small molecules) with the outside of the cell. Many of these solutes undergo passive transport across the membrane. Passive transport occurs without the input of cellular energy. Some solutes are transported into the cell while others are transported out of the cell.Part A - Diffusion All molecules have energy that causes thermal motion. One result of thermal motion is diffusion: the tendency of substances to spread out evenly in the available space. Although the motion of each individual molecule is random, there can be directional motion of an entire population of molecules. Consider a chamber containing two different types of dye molecules, purple and orange. The chamber is divided into two compartments (A and B) by a membrane that is permeable to both types of dye. Initially (left image), the concentration of the orange dye is greater on side A, and the concentration of the purple dye is greater on side B. With time, the dye molecules diffuse to a final, equilibrium state (right image) where they are evenly distributed throughout the chamber. A membrane permeable to both dyes initial condition final condition (equilibrium) Adapted from Biology by Campbell and Reece © 2008 Pearson Education, Inc.
I gave a generic response to this query to emphasize the crucial details that would allow me to draw a conclusion about passive transport.
The movement of particles down their gradient is known as diffusion. Moving down a gradient simply indicates that the particle is attempting to be uniformly distributed throughout, much like dropping food coloring into the water. A gradient is any imbalance in concentration. When we produced our granola, a number of different components came together and dispersed throughout the entire concoction. It doesn't take any energy to move "downhill" during an evening out. Given its ease of passage through cell membranes, water is the chemical most likely to be involved in simple diffusion. Osmosis is the process of water simply diffusing through a medium.
Simple diffusion is essentially what it sounds like: molecules migrate through the membrane according to their gradients. Simple diffusion requires nonpolar* molecules that are tiny enough to fit through the membrane. If the diffusion distance is increased, simple diffusion may become interrupted. The amount of fluid that accumulates in our lungs' alveoli (pulmonary edema) increases the distance that the gases must travel, which reduces their conveyance.
For example, one such transporter channel, GLUT4, is incredibly important in diabetes. Diffusion that is assisted (facilitated) by a membrane transport channel is referred to as facilitated diffusion. These pathways, which are composed of glycoproteins (proteins with linked carbohydrates), allow substances to flow across the membrane. These channels are nearly typically unique to either a specific molecule or a certain class of molecule (such as an ion channel), and as a result, they are closely associated with specific physiological processes. A glucose transporter called GLUT4 is present in skeletal muscle and fat.
Hence, passive transport takes along concentration without energy expenditure.

hold partially completed proteins until the diet provides the missing amino acids.
Cells have the ability to create their own proteins from available amino acids. This is an important process for cell function and survival, and it is necessary for cells to be able to synthesize proteins for a variety of purposes. In order to create their own proteins, cells must do several things.
First, cells must synthesize non essential amino acids that are missing for the protein they are attempting to make. These amino acids are not available in the cell’s amino acid pool, so the cell must synthesize them from other available materials. This is a slow process, so the cell must be patient and wait for the synthesis to finish before beginning the protein synthesis process.
Second, cells must obtain amino acids that are available in the cell’s amino acid pool. This pool is made up of amino acids that the cell can obtain from its environment, such as food or other substances. The cell must look through the available amino acids and select the ones that are necessary for the protein it is trying to create.
Third, cells must slow down protein synthesis until enough of the limiting amino acid is available again. Protein synthesis can be a very fast process, so the cell must be careful not to use too many of the limiting amino acids before the synthesis is complete.

However, where the two occur together, Chthamalus adults are found only in the more stressful upper portions of the habitat where they are more prone to desiccation. This is an example of:
A. competitive exclusion expanding the size of Balanus' realized niche to a larger fundamental niche.
B. intraspecific competition reducing the size of Chthamalus' fundamental niche to a smaller realized niche.
C. mutualism reducing the size of Balanus' realized niche to a smaller fundamental niche.
D. competitive exclusion reducing the size of Chthamalus' fundamental niche to a smaller realized niche.
E. the mutualistic form of symbiosis.
Thus, the correct answer is D.

a collection of dna fragments of various lengths was subjected to electrophoresis. arrange these dna molecules in order, based on the distance they would travel from the well. the molecule that travels the shortest distance should be at the top of the list, and the molecule that travels the greatest distance should be at the bottom of the list.
a. 900 bp
b. 2500 bp
c. 4200 bp
d. 6000 bp
e. 8000 bp
DNA fragments spanning varying lengths were separated using electrophoresis. Depending on how far they would go from the well, their pressures would be 8000 bp, 6000 bp, 4200 bp, 2500 bp, and 900 bp.
How does DNA function? What is it?The instructions required for a creature to grow, endure, and reproduce are encoded in its DNA. Dna fragments must be transformed into information that may be used to build proteins, that are molecules, in order to perform these functions.
Where in the body can you find DNA?Nearly every of the body's cells contains the same DNA. Although some DNA can also be found in the mitochondria, the majority of DNA is found inside structures called chromosomes. The DNA in chromosomes is wound around transcription factors (alkaline proteins).

The video focuses on the lac operon, but there are others. For example, E. coli also have the trp operon, which has genes that code for enzymes necessary for synthesizing tryptophan, an amino acid necessary for protein synthesis. Like the lac operon, the trp operon has multiple genes under the control of one promoter.
Operons can be either inducible or repressible. Inducible and repressible operons share some characteristics, but they are different in key ways. Can you identify whether the lac and trp operons are inducible or repressible?
Sort each phrase to the appropriate bin.
a). The trp repressor protein is inactive, thus that is the right response. b). The promoter can be bound by RNA polymerase,
A trp operon is a collection of genes that code for the enzymes needed to synthesize the amino acid tryptophan. When tryptophan is present in low concentrations, the trp operon is active; conversely, when tryptophan is present, the trp operon is inactive. This is because it is a repressor protein and attenuation (coupled transcription and translation) controlled mechanism.
When tryptophan is present, the repressor binds to the operator of the DNA sequence, blocking the RNA polymerase's path and ending transcription. When tryptophan is absent, the repressor molecule is inactive and RNA polymerase can promote the transcription of genes after binding to the promoter sequence. Therefore, the right response is "inactive and promoter."
