WebGlycogenesis and glycogenolysis are reciprocally regulated. The two opposing, regulated enzymes are glycogen synthase (glycogenesis) and glycogen phosphorylase (glycogenolysis). Each is regulated by phosphorylation/dephosphorylation and by binding of other molecules.

The first step in glycolysis (Figure 9.1.1) is catalyzed by hexokinase, an enzyme with broad specificity that catalyzes the phosphorylation of six-carbon sugars. Hexokinase phosphorylates glucose using ATP as the source of the phosphate, producing glucose-6-phosphate, a more reactive form of glucose. md rent credit

WebI'm confused about glycolysis. Glucagon inhibits PFK-2 which reduces F2,6-BP production and therefore F2,6-BP can't activate PFK-1 to produce F1,6-BP. But glucagon also stimulates the secretion of insulin. Insulin stimulates PFK-1 and therefore production of F1,6-BP. These two things seem counterintuitive pertaining to the role of glucagon.

WebIn glycolysis, Substrate-Level Phosphorylation is the transfer of a phosphate group from a 3 carbon organic molecule to ADP. This reconstitutes ATP which can be used in other important energy consuming processes of the cell. Substrate-Level Phosphorylation is different from Oxidative Phosphorylation which will be discussed in Step 12. WebGlycolysis is a ten-step metabolic pathway that is centered on the processing of glucose for both energy extraction from chemical fuel and for the processing of the carbons in glucose into various other biomolecules (some of which are key precursors of many much more complicated biomolecules).
