Question

respiration overview quick check
in what organelle do the kreb’s cycle and the electron transport chain take place?
(1 point)
○ cytoplasm
○ mitochondria
○ chloroplast
○ nucleus

Explanation:

To solve this, we analyze each option:

• Cytoplasm: Glycolysis (part of cellular respiration) occurs here, not Kreb’s cycle or electron transport chain.
• Mitochondria: The Kreb’s cycle (citric acid cycle) takes place in the mitochondrial matrix, and the electron transport chain is in the inner mitochondrial membrane.
• Chloroplast: Involved in photosynthesis, not cellular respiration's Kreb’s cycle or electron transport chain.
• Nucleus: Contains genetic material and is not involved in these respiration processes.

Answer:

B. mitochondria
