WebDec 24, 2024 · It is followed by the Krebs cycle and oxidative phosphorylation to produce ATP. Glycolysis is the first of the main metabolic pathways of cellular respiration to produce energy in the form of ATP. Through two distinct phases, the six-carbon ring of glucose is cleaved into two three-carbon sugars of pyruvate through a series of enzymatic reactions. WebDec 30, 2024 · Acetyl-Coenzyme A is composed of four distinct molecular parts. 1. Once the pyruvate enters the mitochondrial matrix, the pyruvate dehydrogenase complex (consisting of three enzyme subunits E1, E2, and E3) converts it to acetyl-CoA (Figure 5.3. 3) for entry into the tricarboxylic acid cycle (TCA). This reaction generates NADH and liberates CO 2.
