Answer:
binding regulatory subunits and inducing their release from the catalytic subunits
Explanation:
cAMP molecules diffuse into the cytoplasm where they bind to an allosteric site on a regulatory subunit of a cAMP-dependent protein kinase ( protein kinase A, PKA).
-In its inactive form, PKA is a heterotetramer comprised of two subunits namely, regulatory (R) and two catalytic (C) subunits.
-The regulatory subunits normally inhibit the catalytic activity of the enzyme. cAMP binding causes the dissociation of the regulatory subunits, thereby releasing the active catalytic subunits of PKA.
-cAMP stimulates glucose mobilization by activating a protein kinase that adds a phosphate group onto a specific serine residue of the glycogen phosphorylase polypeptide.
Answer:
The correct answer is - option A.
Explanation:
Among all of the given options the best character of the bacterial cell is the size of the cell which ranges in between 0.5 to 2 microns. The best evidence for the presence of bacterial cell is the smaller size of the cells.
Rest of the characters provided in the options does not matches with the characteristics of bacterial cells and not related to the bacteria.
Thus, the correct answer is option A.
Answer:
Carbon is the basic building block to most cells in the body. It helps with cellular respiration by which your body releases energy stored in glucose and the glucose compound is composed of carbon, hydrogen, and oxygen.
Explanation:
The correct answer to this open question is the following.
Although you did not include the article or a link to it, we can comment on the following general terms.
The controversy between the two terms in the area of Psychology stems from de debate if the behavior in humans is inherited by the parents or it is acquired when the individual starts to socialize. This means that the two schools of thought are debiting on the idea of if the behavior is learned or if it is the product of the genetic.
So Nature for scientists is the information that is conveyed by genetics and is passed from parents to children. Here, biology and chemistry play a major factor.
On the other hand, Nurture can be understood as environmental factors that the individual is exposed to when it receives the external influence and starts to learn new things and how to react to these external influences.
When a somatic cell is mutated, none of the other cells in the organism mutate with it. Screenings usually detect mutations that are in numerous cells and not in just one. That is why a mutation in a somatic cell of a multicellular organism escape detection.
<h3>What are mutations?</h3>
A mutation in biology is an adjustment to the nucleic acid sequence of an organism's, virus's, or extrachromosomal DNA. DNA or RNA can be found in the viral genome. Errors in DNA replication, viral replication, mitosis, meiosis, or other types of DNA damage (such as pyrimidine dimers from exposure to ultraviolet radiation) can result in mutations.
These errors can then lead to error-prone repairs, particularly microhomology-mediated end joining, error-causing repairs, or errors during replication. Due to mobile genetic elements, mutations can also result from the insertion or deletion of DNA segment.
