The production of cAMP directly regulated by two enzyme, ___________ and_______. This former is ___________ a protein, when latter is a _________ protein.
a. phospodiesterase (PED),Adenylyl ccyclase(AC), cytosolic, peripheral.
b. PDE, AC, peripheral, cytosolic
C.Adenylyl kinase, phosphorylase A, peripheral, cytosolic
D. Adenylyl ccyclase(AC), phospodiesterase (PED), integral and peripheral.
I think the right answer is "D", but not sure, please check
To determine the correct answer, let's analyze the information provided.
The question states that the production of cAMP is directly regulated by two enzymes. We need to identify these enzymes and their characteristics.
The first enzyme mentioned is "phospodiesterase (PED)." This is likely a typo, as the correct term is "phosphodiesterase" (PDE). Phosphodiesterase is known to break down cAMP, therefore regulating its levels.
The second enzyme mentioned is "Adenylyl cyclase (AC)." Adenylyl cyclase is responsible for synthesizing cAMP and, hence, directly regulates its production.
According to the question, the former enzyme (PDE) is "integral," while the latter enzyme (AC) is "peripheral." However, this information is incorrect. Both enzymes can be either integral membrane proteins or peripheral membrane proteins, depending on their specific location within the cell.
Therefore, based on the correct enzyme names and disregarding the incorrect information about their protein nature, the correct answer appears to be:
D. Adenylyl cyclase (AC), phosphodiesterase (PDE), integral and peripheral.
Please note that in case of any discrepancy between the information provided and known scientific knowledge, it is essential to prioritize the latter.
