Glycolysis
Multiple Choice
Glycolysis is a cytosolic pathway, not a mitochondrial one; in a eukaryotic cell, where does glycolysis primarily take place?
A
On the inner mitochondrial membrane (cristae)
B
In the intermembrane space of mitochondria
C
In the mitochondrial matrix
D
In the cytosol (cytoplasm)
Verified step by step guidance1
Understand the cellular compartments involved in energy metabolism: mitochondria and cytosol.
Recall that glycolysis is the metabolic pathway that breaks down glucose into pyruvate, producing ATP and NADH.
Recognize that glycolysis occurs outside the mitochondria, specifically in the cytosol (also called cytoplasm) of eukaryotic cells.
Differentiate glycolysis from other pathways like the citric acid cycle and oxidative phosphorylation, which occur inside mitochondria (matrix and inner membrane).
Conclude that the correct location for glycolysis in a eukaryotic cell is the cytosol, not any mitochondrial compartment.
