Chapter 9.4, Problem 1R

Summary Introduction

To review:

The necessity of replenishing oxidized nicotinamide adenine dinucleotide (NAD⁺) in continuing glycolysis in the absence of oxygen (O₂).

Introduction:

Glycolysis is the catabolic pathway of oxidizing glucose to release energy in the form of ATP (adenosine triphosphate). This reaction occurs in the cell’s cytoplasm. In the absence of oxygen or during anaerobic conditions, the energy generation pathway switches to fermentation instead of oxidative phosphorylation after the glycolytic pathway.
