Vedclass · Answer

(D) Calcium $(Ca^{2+})$ acts as a crucial cofactor for many enzymes and signaling pathways. $1$. Nitric oxide synthase requires calcium/calmodulin for its activation. $2$. Protein phosphatase (specifically calcineurin) is calcium-dependent. $3$. Adenylate kinase is a magnesium-dependent enzyme $(Mg^{2+})$ and does not require calcium for its catalytic activity. $4$. Hexokinase is also primarily magnesium-dependent $(Mg^{2+})$ for the phosphorylation of glucose. However,in the context of standard biochemical questions regarding calcium-dependent enzymes,Adenylate kinase is the classic example of an enzyme that does not utilize calcium as a cofactor.

Calcium in the human diet is $NOT$ required for the activity of which of the following?
