Question

For each of the pathways listed below, write a numbered list identifying- 1) What is(are) the main substrate(s) for that pathway? 2) What is (are) the final product(s) for that pathway? 3) What is the energy yield (ATP, NADH, ...) for that pathway? 4) Where in the cell (be specific) does the pathway occur?

ANSWER ALL parts to the question (1,2,3,4) Make sure you are correct.

Answer 1

Answer- A) Glycolysis :-

1- substrate = Glucose

2- Final product = 2 molecules of Pyruvate, 2 ATP & 2 NADH.

3- Energy yield = 2 molecules of ATP & 2 molecules of NADH.

4- occurs in cytosol

B) Pyruvate Oxidation:-

1- substrate = Pyruvate

2- final product = 2 CO₂ , 2 NADH & 1 acetyl-CoA.

3- Energy yield = 2 molecules of NADH, 1 molecule of FADH2 & 1 molecule of ATP are produced.

4- occurs in mitochondrial matrix

C) Citric Acid cycle:-

1- substrate = pyruvate

2- Final products = 2 CO₂, 2 ATP, and 6 NADH and 2 FADH₂

3- Energy yield = 2 ATP, 6 NADH & 2 FADH2

4- occurs in mitochondria
