Answer 1

Answer:

E. 2 mol pyruvate, 2mol ATP, 2mol NADH, 0mol glyceraldehyde-3-phosphate.

Explanation:

Glycolysis occurs in the process of cellular respiration. In this process , glucose molecule is broken down and produces 2 mole of pyruvate, 2 mole of ATP and 2 mole NADH. There is no glyceraldehyde-3-phosphate is produced in this process. This process occurs both with or without the addition of oxygen. There are 10 enzymes which are responsible for the breakdown of glucose molecule.

Answer 2

Answer:

The answer is: B.2mol ATP, 0mol NADH, 2mol glyceraldehyde-3-phosphate, 0mol pyruvate

Explanation:

Glycolysis occurs in the cytoplasm of the cell. During glycolysis, one mole of glucose is transformed into two moles of pyruvate. This process has two phases, a first phase of ATP utilization and a second phase of ATP production. The first phase of inversion is important since glucose is broken down. During the first phase, glucose is phosphorylated and transformed into 2 moles of 3-phosphoglyceraldehyde, using 2 moles of ATP. The reaction is as follows:

Glucose→Glucose-6-phosphate→fructose-6-phosphate→fructose-1,6-bisphosphate→2*3-phosphoglyceraldehyde
