Question

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

○ glycolysis
○ krebs cycle
○ electron transport chain
○ both b and c

Explanation:

To determine which steps of cellular respiration occur in the mitochondria, we analyze each option:

• Glycolysis (Option A): Occurs in the cytoplasm, not the mitochondria.
• The Krebs Cycle (Option B): Takes place in the mitochondrial matrix.
• Electron Transport Chain (Option C): Occurs in the inner mitochondrial membrane.

Since both the Krebs Cycle (B) and the Electron Transport Chain (C) occur in the mitochondria, the correct answer is "Both B and C".

Answer:

Both B and C (B. The Krebs Cycle, C. Electron Transport Chain)
