Where does glycolysis occur?
A.Cytosol
B.Mitochondrial matrix
C.Inner mitochondrial membrane
D.Nucleus
Explanation
Core Concept
Glycolysis occurs in the cytosol and does not directly require molecular oxygen. It converts glucose to pyruvate while producing a small amount of ATP and reducing NAD+ to NADH. Continued glycolytic flux requires regeneration of NAD+, which can occur through respiration or fermentation depending on the organism and conditions.
Correct Answer
ACytosol
