Glycolysis
Multiple Choice
Does glycolysis occur in the mitochondria in eukaryotic cells?
A
Yes; glycolysis occurs in the mitochondrial matrix.
B
No; glycolysis occurs in the nucleus where glucose is phosphorylated.
C
Yes; glycolysis occurs on the inner mitochondrial membrane.
D
No; glycolysis occurs in the cytosol (cytoplasm), not in the mitochondria.
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 (cytoplasm) of the cell, which is the fluid portion outside the organelles, including mitochondria.
Recognize that mitochondria are the site of other metabolic processes such as the citric acid cycle and oxidative phosphorylation, but not glycolysis.
Note that the nucleus is primarily involved in storing genetic material and regulating gene expression, not in glycolysis or glucose phosphorylation.
Conclude that glycolysis does not occur in the mitochondria or nucleus, but specifically in the cytosol, making the correct answer: No; glycolysis occurs in the cytosol (cytoplasm), not in the mitochondria.
