Question

which step(s) of cellular respiration occurs in the cytoplasm? * a glycolysis b the krebs cycle c electron transport chain glycolysis krebs cycle electron transport chain both b and c

Explanation:

To determine which step of cellular respiration occurs in the cytoplasm, we analyze each option:

• Option A (Glycolysis): Glycolysis is the first step of cellular respiration, and it takes place in the cytoplasm of the cell. Glucose is broken down into pyruvate here.
• Option B (The Krebs Cycle): The Krebs Cycle (also known as the Citric Acid Cycle) occurs in the mitochondrial matrix, not the cytoplasm.
• Option C (Electron Transport Chain): The Electron Transport Chain is located in the inner mitochondrial membrane, not the cytoplasm.

So, only Glycolysis occurs in the cytoplasm.

Answer:

A. Glycolysis
