D. NADH

Answer 4
A. ADP, FADH2, NADH

B. ATP, FADH2

C. ATP

D. NAD+

Answer 1

MAY BE THE ANSWER IS (2) BECAUSE GLYCOSIS IS THE PROCESS IN WHICH THE CONVERSION OF 6 C GLUCOSE INTO PYRUVATE INSIDE THE CYTOPLASM

Answer 2

The Option 2

A. pyruvic acid, ATP, NADH

B. ATP, FADH2, NADH

C. ATP

D. NAD+

Step-by-step explanation:

In glycolysis, which is the breakdown of glucose into two molecules of pyruvate with the release of energy, the major products are pyruvate, ATP and NADH, which is an energy electron carrier, and this process begins in the cytoplasm.

Krebs' Cycle occurs in the presence of oxygen releasing one molecule of guanosine triphosphate which donates one phosphate group to ADP to form ATP, three molecules of NAD which is then reduced to NADH, one molecule of FAD which is reduced to FADH2.

In electron transport chain, ATP is produced. In lactic acid fermentation, which is the pathway involved in the absence of oxygen releasing NAD+ as its major product.
