Which process does not occur in the mitochondria?
A

C
Glycolysis
D
Oxidative Phosphorylation
Verified step by step guidance1
Begin by understanding the role of mitochondria in cellular respiration. Mitochondria are known as the powerhouse of the cell, where most of the ATP is produced through aerobic respiration.
Identify the processes that occur within the mitochondria. The key processes include the Electron Transport Chain, Citric Acid Cycle (also known as Krebs Cycle), and Oxidative Phosphorylation.
Understand the location of Glycolysis. Glycolysis is the first step in cellular respiration and occurs in the cytoplasm of the cell, not in the mitochondria.
Review the sequence of cellular respiration: Glycolysis occurs in the cytoplasm, followed by the Citric Acid Cycle and Electron Transport Chain in the mitochondria.
Conclude that Glycolysis is the process that does not occur in the mitochondria, as it takes place in the cytoplasm.
