Substrate level phosphorylation occurs during which step of Krebs

WebUnlike glycolysis, the citric acid cycle is a closed loop: the last part of the pathway regenerates the compound used in the first step. The eight steps of the cycle are a series of redox, dehydration, hydration, and decarboxylation reactions that produce two carbon dioxide molecules, one GTP/ATP, and the reduced carriers NADH and FADH 2 . WebCorrect option is A) During Krebs' or citric acid cycle, succinyl-CoA is acted upon by enzyme succinyl-CoA synthetase to form succinate (a 4C compound). The reaction releases sufficient energy to form ATP (in plants) or GTP (in animals) by substrate-level phosphorylation. GTP can form ATP through a coupled reaction. WebGTP and ATP can be converted into each other by the enzyme nucleosiddiphosphatkinase: GTP + ADP → GDP + ATP. This enzyme transfers the phosphate group from GTP to … father rene mcgraw

"WebSteps in the Citric Acid Cycle. Step 1. The first step is a condensation step, combining the two-carbon acetyl group (from acetyl CoA) with a four-carbon oxaloacetate molecule to form a six-carbon molecule of citrate. CoA is bound to a sulfhydryl group (-SH) and diffuses away to eventually combine with another acetyl group. " - Gtp in krebs cycle
