18)which of the following would be considered a second messenger ?
19)for a protein to be an integral membrane protein, it would have to have a ___ region
QUESTION 18 Which of the following would be considered a second messenger? Calcium B. CAMP CAcetylcholine D. A& B E. B, & C QUESTION 19 For a protein to be an integral membrane protein, it would have to have a region polar polar c charged exposed E. hydrophobic QUESTION 20 Phosphorylation cascades resuk n which of the following A amplification of a signal B. inversion of a signal C directly stimulate gene expression D. A & B E. B, & C Solution
18)
The calcium and cAMP are the major secondary messengers for several enzymes. Therefore, the correct option is (D) A&B.
19)
Every integral protein should have a hydrophobic region so that it could integrate into the membrane. Therefore, the correct option is (E).
20)
phosphorylation cascades result in which of the following amplification of singal. Thus, the correct option is (a) only.
