Vedclass · Answer

(D) Calcium $(Ca^{2+})$ acts as an essential cofactor or activator for various enzymes in biological systems.Nitric oxide synthase $(NOS)$ is a well-known enzyme that requires calcium/calmodulin for its activation.Protein phosphatase $(2B)$,also known as calcineurin,is a calcium-dependent serine/threonine phosphatase that is directly regulated by calcium binding.Therefore,both nitric oxide synthase and protein phosphatase are regulated by calcium.Thus,the correct option is $(D)$.

Which enzyme's activity is regulated by calcium as a cofactor?
