a) sucrose; lactic acid; FADH
b) galactose; H2O; ATP
c) pyruvate; ATP; NADH
d) acetyl-CoA; ADP; Pi
e) lactic acid; O2; acetaldehyde"

Answer 1

In glycolysis, glucose is converted into two pyruvate molecules, yielding two ATP and two NADH molecules in the process. The correct answer is c) pyruvate; ATP; NADH.

Step-by-step explanation:

In glycolysis, one molecule of glucose containing six carbons is converted to two molecules of pyruvate, each containing three carbons. This reaction also yields two molecules of ATP and two molecules of NADH. The correct answer to the question is option c) pyruvate; ATP; NADH.

Glycolysis is the process where a six-carbon glucose molecule is split into two three-carbon pyruvate molecules. During this process, some of the chemical energy that was stored in glucose is transferred to ATP and NADH. In summary, this phase of cellular respiration produces a net gain of two ATP molecules and two NADH molecules per glucose molecule, while generating pyruvate that can further enter into the Krebs cycle under aerobic conditions or be used in other metabolic pathways under anaerobic conditions.
