q1
in glycolysis, glucose is
broken down into two
molecules of what?
a. pyruvate
b. fructose
c. acetyl-coa
d. lactate
diagram of glycolysis
a. pyruvate
b. fructose
c. acetyl-coa
d. lactate

Explanation:

Glycolysis is the metabolic pathway that breaks down glucose. In this process, one molecule of glucose (a 6 - carbon sugar) is broken down into two molecules of pyruvate (a 3 - carbon compound). Fructose is a different sugar and not the end product of glycolysis. Acetyl - CoA is formed from pyruvate in the next step of cellular respiration (the link reaction), not directly from glycolysis of glucose. Lactate is the end product of lactic acid fermentation, which is a different pathway that can follow glycolysis in the absence of oxygen, but not the direct product of glycolysis.

Answer:

A. Pyruvate
