Glycolysis is the first step in cellular respiration. Which option best summarizes the process?
A. aerobic; 6-carbon glucose forms four 3-carbon pyruvates; forms a net total of 3 ATP
B. anaerobic; 6-carbon glucose forms two 3-carbon pyruvates; forms a net total of 2 ATP
C. aerobic; 6-carbon glucose forms three 2-carbon pyruvates; forms a net total of 2 ATP
D. anaerobic; 6-carbon glucose forms two 3-carbon pyruvates; forms a net total of 4 ATP

Answer: B

Explanation:
In both aerobic and anaerobic respiration, glycolysis of 1 glucose molecule (6C) will produce 2 pyruvate (3C).
Glycolysis use 2 ATP and produce 4 ATP, so the net total energy produce is 2 ATP

Glycolysis of 1 glucose molecule also produce 2 NADH

Glycolysis is anaerobic and it involves 6-carbon glucose forming two 3-carbon pyruvate and a net production of 2 ATP.

WHAT IS GLYCOLYSIS?

Glycolysis is the first step of cellular respiration in all living organisms. It involves the breaking down of glucose molecule to form pyruvate molecules and 2 ATP molecules.

Glycolysis is an anaerobic process, hence, it does not require oxygen to occur. This is why every living organism can undergo glycolysis.

In summary of the process of glycolysis, it is an anaerobic process involving the formation of 3-carbon pyruvate from 6-carbon glucose and a net production of 2 ATP molecules.
