The answer is endocrine system. It includes all of the glands of the body and the hormones produced by those glands. The glands are controlled directly by stimulus from the nervous system as well as by chemical receptors in the blood and hormones produced by other glands. By regulating the roles of the organs in the body, these glands help to continue the body’s homeostasis. Cellular metabolism, reproduction, sexual development, sugar and mineral homeostasis, heart rate, and digestion are amid the several processes controlled by the actions of hormones.

C. GDP is phosphorylated to produce GTP</span>
Substrate level phosphorylation occurred in
kreb cycle inform of metabolic reaction that involve the transfer of phosphoryl
group to GDP or ADP from another phosphorylated compound which result into
formation of GTP or ATP. This process commonly occurs in the cytoplasm of cells
during glycolysis and also in the mitochondria during krebs cycle.
