Membrane-bounded vesicles that contain enzymes for oxidizing small organic molecules with the formation of hydrogen peroxide are Group of answer choices
Answer:
peroxisomes
Explanation:
The peroxisomes represent one of the organelles of the cell. They are usually small and characterized by membrane-bound vesicles that contain oxidative enzymes.
The enzymes in peroxisomes are involved in the oxidation of organic molecules - a process that leads to the formation of hydrogen peroxide. The later is further converted to water and oxygen by the constituent catalase enzyme of the peroxisomes. Fatty acids are also oxidized in peroxisomes but instead of hydrogen peroxide, acetyl groups that are utilized in other biosynthetic reactions are produced.

Transcriptional regulation of operon gene expression involves the interaction of molecules with one another and of regulatory molecules with segments of DNA. In this context, define and give an example of each of the following:
a. operator
b. repressor
c. inducer
d. corepressor
e. promoter
f. positive regulation
g. allostery
h. negative regulation
i. attenuation
Answer and explanation:
The operator is a DNA fragment localized between the promoter and structural gene sequences that are able to repress operon transcription. A repressor is a molecule that binds to the operator to inhibit transcription, while an inducer is a molecule that activates transcription by binding either to the repressors or to the activators. A corepressor is a molecule that binds to repressors in order to activate them. A promoter is a DNA sequence localized upstream structural genes which binds to a transcription factor in order to activate operon transcription. Positive regulation is the process by which operon transcription acts as a positive loop, thereby increasing its own transcription, while negative regulation is the process by which operon transcription inhibits its own expression. Allostery refers to the process by which a molecule regulates operon transcription by binding to distal (and therefore non-functional) sites of the operon. Attenuation is a process able to reduce operon transcription and also to block subsequent translation.
Which of the following is responsible for the conversion of covalently closed circular DNA to supercoiled DNA of the plasmid of: a) endonuclease b) DNA gynase c) topa isomerase d) exonuclease
Answer:
DNA gyrase
Explanation:
DNA gyrase is a bacterial enzyme that plays an important role in catalyzing the negative supercoiling of circular chromosomal DNA. This enzyme belongs to a class of enzymes called topoisomerases which play a major role in transitioning of DNA structure. DNA gyrase conversion of covalently closed circular DNA to supercoiled DNA is ATP-dependent.
The importance of DNA gyrase cannot be overemphasized, because for DNA synthesis to occur, the DNA must have a single-stranded template, hence, DNA gyrase play an important role in unwinding the double-stranded DNA for replication. It has the ability to introduce negative supercoils and relax positive supercoils prior to replication.

Very small changes in the solute concentrations in the various fluid compartments cause water to move from one compartment to another, which alters blood composition and blood pressure. How do the following physiological changes affect blood pressure?
a. Decrease water reabsorption
b. Decrease peripheral resistance
c. Vasodilation
d. Decrease salt intake
e. Decrease blood volume
f. Vasoconstriction
g. Increase peripheral resistance
h. Increase salt intake
i. Increase blood volume
j. Increase water reabsorption
Answer:
a. Decrease water reabsorption : decrease blood pressure.
b. Decrease peripheral resistance : decrease blood pressure
c. Vasodilation : decrease blood pressure
d. Decrease salt intake : decrease blood pressure
e. Decrease blood volume : decrease blood pressure
f. Vasoconstriction : increase blood pressure
g. Increase peripheral resistance: increase blood pressure
h. Increase salt intake: increase blood pressure
i. Increase blood volume : increase blood pressure
j. Increase water reabsorption: increase blood pressure
Explanation:
Total peripheral resistance: This term refers to the resistance offered by the vascular system to the blood flow. This resistance is a result of the friction between the blood and the vessel's walls. In other words, it is the opposition of the vessels to blood flow. The total peripheral resistance is the summary of all the bloody circuit resistances in the body. Those mechanisms that induce vasoconstriction conduce to an increase in total peripheral resistance, while mechanisms that induce vasodilation provoke a decrease in total peripheral resistance. Blood pressure: This term refers to the strength applied by the blood against the vessel walls as it flows. This pressure is determined by the bombed blood strength and the volume as well as by the vessel size and flexibility. Blood pressure changes continuously according to the activity, temperature, diet, emotional state, among others. Salt ingestion causes an increase in plasmatic osmolarity, stimulates thirst, and hence, water ingestion. Sodium retains water, expanding the blood volume and causing an increase in vessel pressure. The antidiuretic hormone, also known as vasopressin hormone, is released by changes in serum osmolarity or blood volume. Its function is to keep homeostasis and make kidneys conserve or keep water by concentrating urine and by reducing its volume. By these actions, the antidiuretic hormone stimulates water reabsorption, according to the organism´s needs. Kidneys control blood pressure in many ways. If the pressure is elevated, kidneys produce the loss of salt and water, normalizing arterial pressure. But if pressure is low, kidneys conserve water.Based on the data table below, which number would be the BEST choice for the top number of the scale on the vertical axis of a scatter plot showing this data?
Answer:
D. 70
Explanation:
From the table given, we can easily tell that distance (m) is dependent on time (s). Distance is a dependent variable, while time is an independent variable.
If both variables were to be plotted to show the relationship between them on a scatter plot, the dependent variable is usually plotted on the vertical axis (y-axis), while the independent variable would be plotted on the horizontal axis (x-axis).
Distance would be in the vertical axis, while time would be in the horizontal axis.
Therefore, the BEST choice for the top number of the scale on the vertical axis would certainly be 70, because the highest value for distance (m) on the table of values is 69.

If bacteria transformed with a recombinant pUC18 plasmid produce white colonies when grown on plates containing ampicillin and Xgal, which of the following is least likely?
a. They produce β-lactamase that provides resistance to ampicillin.
b. They carry a vector that contains a DNA fragment inserted into the multiple cloning site.
c. They produce functional β-galactosidase that cleaves X-gal.
d. They carry a vector with a lacZ gene that has been disrupted and rendered nonfunctional.
e. They carry a vector with the bla gene used as the selectable marker.
Answer:
c. They produce functional β-galactosidase that cleaves X-gal.
Explanation:
β-galactosidase is an enzyme capable of catalyzing the enzymatic hydrolysis of β-galactosides into monosaccharides by hydrolyzing the β-glycosidic bond. On the other hand, X-gal is an analog of lactose composed of galactose, which is widely used in laboratories for the detection of β-galactosidase. In the presence of β-galactosidase, X-gal is hydrolyzed by cleaving its β-glycosidic bond, thereby confirming the presence of β-galactosidase.
