Question

Cellular respiration generates a total of 36 to 38 ATP molecules. How many of these come solely from glycolysis

Answer 1

look at the pathway (or the summary) in your textbook.

Answer 2

The cellular respiration yields nearly 38 ATP molecules. This is due to
In cytosol Glycolysis process starts, the enzyme glyceraldehyde-3-phosphate dehydrogenase enzyme forms 6ATP (one NADH = 3ATP. so, two NADH produced) and 1,3-bisphosphoglycerate kinase forms 2ATP, pyruvate kinase generates 2ATP. So, total 10 ATP. Initially the enzyme hexokinase enzyme utilize 2ATP molecules. So, the net ATP molecules in glycolysis is 8ATP. The end product aerobic glycolysis is pyruvate.

The pyruvate molecule is entered into mitochondria, then the citric acid cycle starts. The conversionn of pyruvate to acetyl CoA forms 6ATP (2NADH), isocitrate dehydrogenase form 6ATP, alpha keto glutarate dehydrogenase forms 6ATP, succinate thiokinase forms 2ATP, succinate dehydrogense forms 4 ATP (two FADH2= 4 ATP), and malate dehydrogenase forms 6 ATPs so, the net ATP for citric acid cycle is 30 ATP
The net ATP synthesis in cellular respiration is 8 ATP (glycolysis) + 30 (citric acid cycle) =38 ATP.

thanksss:)
