Homework Answers

Answer #1

Glycolysis, there are total 10 steps which converts 1 glucose molecules into 2 pyruvate molecules. In that process energy is consumed in the form of ATP at step 1 and 3 in which conversion of glucose into glucose 6 phosphate consumed 1 ATP and conversion of fructose 6 phosphate to fructose 1, 6 bisphosphate also consumed 1 ATP. The energy is produced in step 6 where 2 molecules of glyceraldehyde 3 phosphate get converted into 2 molecules of 1, 3 bisphosphoglycerate by 2NAD+ to 2NADPH. Further in step 7, this 1, 3 bisphosphoglycerate is converted into phosphoglycerate which generates 2 molecules of ATP. Another 2 molecules ATP is produced in step 10, where 2 molecules of phosphoenol pyruvate is get converted into 2 molecules of pyruvate.

Ans : 4 ATP, 2NADH, 2pyruvate will produced from 1 glucose molecule in glycolysis.
