Question

The process in which glucose is broken down into pyruvic acid is ______.

Options

• Acetylation

• Krebs cycle

• ETS

• Glycolysis

Answer 1

The process in which glucose is broken down into pyruvic acid is glycolysis.

Explanation:

Glycolysis is the initial stage of cellular respiration that occurs in the cell's cytoplasm. In this process, a single six-carbon glucose molecule is enzymatically broken down into two three-carbon pyruvic acid molecules, generating a small amount of ATP and NADH.
