Glycolysis
Multiple Choice
In eukaryotic cells, does glycolysis occur in the mitochondria?
A
Yes; glycolysis occurs on the inner mitochondrial membrane.
B
No; glycolysis occurs in the cytosol, not in the mitochondria.
C
Yes; glycolysis occurs in the mitochondrial intermembrane space.
D
Yes; glycolysis occurs in the mitochondrial matrix.
Verified step by step guidance1
Recall the cellular location of glycolysis in eukaryotic cells. Glycolysis is the metabolic pathway that breaks down glucose into pyruvate, producing ATP and NADH.
Understand that glycolysis occurs in the cytosol, which is the fluid portion of the cytoplasm outside the organelles, including mitochondria.
Recognize that mitochondria are the site of other metabolic processes such as the citric acid cycle (Krebs cycle) and oxidative phosphorylation, but not glycolysis.
Note that the inner mitochondrial membrane, intermembrane space, and mitochondrial matrix are involved in different stages of cellular respiration, but glycolysis specifically does not take place in any of these mitochondrial compartments.
Conclude that the correct statement is that glycolysis occurs in the cytosol, not in the mitochondria.
