How many atp does glycolysis cost

WebApr 9, 2024 · Step 1. The first step in glycolysis (Figure 7.2. 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. WebSome books state 36 ATP per glucose but this occurs in cells that convert the 2 NADHs made in glycolysis into 2 FADH2s when they enter the mitochondria where Krebs cycle and ETC occur. (It is a transporter phenomenon and has nothing to do with using ATP.) If you do the math, you end up with 2 less ATP. This approach has worked well for over 30 ...

In gluconeogenesis the conversion of pyruvate to PEP, the conversion of fructose-1,6-bP, and the conversion of glucose-6-P to glucose all occur very spontaneously which is why these processes are highly regulated. WebThe first stage of cellular respiration is glycolysis. It does not require oxygen. During glycolysis, one glucose molecule is split into two pyruvate molecules, using 2 ATP while producing 4 ATP and 2 NADH molecules.
