Question

What are the main products/reactants/steps for each:

Glycolysis is part of cellular respiration:

Citric Acid cycle part of cellular respiration

Electron transport/oxidative phosphorylation part of cellular respiration

Answer 1

Glycolysis is a ten step anaerobic process which breaks down one molecule of Glucose into 2 Molecules of Pyruvate. Input of 2 ATP is required to kick start the glycolysis. The net energy yield from glycolysis, per glucose molecule, is 2 ATP plus 2 NADH

1 Molecule of Pyruvate then combines with Coenzyme A forming Acetyl CoA and  enters the Citric acid cycle. The Pyruvate is broken down into three CO2 molecules, including the molecule of CO2 released during the conversion of pyruvate to acetyl CoA. The cycle generates 1 ATP per turn of Pyruvate.Most of the chemical energy is transferred to NAD+ and FAD to form 3 molecules of NADH and 2 molecules of FADH2.

In the electron transport chain  a series of electron transporters embedded in the inner mitochondrial membrane that shuttles electrons from NADH and FADH2 to molecular oxygen. In this process the NADH and FADH2 are oxidised and ATP is produced by oxidative phosphorylation.
