Question

The hydrogen atoms that reduce pyruvic acid are taken from a molecule we call ________.

Answer 1

The molecule that provides the hydrogen atoms to reduce pyruvic acid is NADH.

Step-by-step explanation:

The molecule that provides the hydrogen atoms to reduce pyruvic acid is called NADH. During glycolysis, NAD+ is reduced to NADH by accepting hydrogen atoms from glucose. The NADH then carries the electrons to later pathways for ATP production.
