WebThe citric acid cycle is a metabolic pathway that connects carbohydrate, fat, and protein metabolism. The reactions of the cycle are carried out by eight enzymes that completely oxidize acetate (a two carbon molecule), in the form of acetyl-CoA, into two molecules each of carbon dioxide and water. WebThe higher the enzyme concentration the ______ the rate of the reaction. Higher. Match the stage of glucose oxidation with the total ATP or electron carrier production. Glycolysis = 2 ATP , 2 NADH. Intermediate stage = 2 NADH. Citric acid cycle = 2 ATP , 6 NADH , 2 FADH2.

WebThe Calvin cycle reactions (Figure 5.15) can be organized into three basic stages: fixation, reduction, and regeneration. In the stroma, in addition to CO 2, two other chemicals are … Web1. The enzyme and the substrate are in the same area. Some situations have more than one substrate molecule that the enzyme will change. 2. The enzyme grabs on to the substrate at a special area called the active site. The combination is called the enzyme/substrate complex. Enzymes are very, very specific and don't just grab on to …
