In anaerobic respiration , one molecule of glucose is broken down into two molecules

In anaerobic respiration , one molecule of glucose is broken down into two molecules of pyruvate which are then converted to lactate

Explanation:

Cellular respiration is the process by which cells metabolize glucose through various steps and pathways to produce energy in the form of ATP molecules. Cellular respiration is of two types: aerobic and anaerobic respiration. Oxygen is present in aerobic respiration to accept the electrons produced in glycolysis whereas it is absent in anaerobic respiration.

In anaerobic respiration, glucose is broken down in ten reaction steps into two molecules of pyruvate. Two net ATP molecules are also released.

The overall equation for glycolysis is: glucose + 2 ATP ⟶ 2 pyruvate + 2 NADH + 4 ATP + 2 H2O

The two pyruvate molecules produced are then converted to lactate when they accept electrons from NADH molecules. The equation is given below:

2 pyruvate + 2NADH ⟶ 2 Lactate + 2 NAD+

the answer is c. it will give up it's valence electron to the other atom.
