Answer 1

Glycolysis occurs in cytoplasm.

Glycolysis converts a molecule of glucose into two molecules of pyruvate. The net products of this process are two molecules of ATP  and two molecules of NADH.

Transition reaction: transition between glycolysis and citric acid cycle

It takes place in the matrix of mitochondria

This stage converts two molecules of pyruvic acid that was formed in glycolysis to two molecules of acetyl cenzyme A. In addition it produces CO2 and NADH.

Kreb cycle

It takes place in the matrix of mitochondria.

Each molecule of acetyl co enzyme A produced in transition phase forms 2 molecules of CO2, 3 molecules of NADH, one molecule of FADH2 and one molecule of ATP. Since each molecule of glucose forms 2 acetyl coenzyme A so the total production after 2 rounds of kerb cycle = 2 *( 2 molecules of CO2, 3 molecules of NADH, one molecule of FADH2 and one molecule of ATP).
