Answer #1

Correct answer is (B) DAG.

Explanation :-

DAG remains in the inner layer of the plasma membrane. It recruits Protein kinase C (PKC) - a calcium-dependent kinase that phosphorylates many other proteins that bring about the changes in the cell. As its name suggests, activation of PKC requires calcium ions.These are made available by the action of the other second messenger - IP3.

(A) is wrong answer because it has written bad, which is incorrect.

(C) is wrong answer because it has written cAMP, Which is incorrect.

(D) is wrong answer because it has written calcium, which is incorrect.

Which statement is true about a plasma membrane? Group of answer choices It is a rigid structure that protects the cell like a shell. It is composed of a single layer of phospholipids. The molecules that make up most of the plasma membrane are polar at their heads and tails. The molecules that make up the membrane are phospholipids. The molecules making up the plasma membrane are locked in place.

Which of the following is (are) not characteristics of the pathways activated by second messengers? Some phosphatases and protein kinases in the pathway have numerous proteins as their substrates; others act on only a single protein substrate or a single amino acid of a protein substrate. Alterations in the conformations of signaling proteins are often accomplished by protein kinases and protein phosphatases that, respectively, add or remove phosphate groups from other proteins. Each protein in the pathway typically acts by...
