Question
Where does cellular respiration take place in eukaryotic cell?
- cytoplasm and mitochondria
- cytoplasm and nucleus
- nucleus and mitochondria
- mitochondria only
Solution
Answer
Cellular respiration in eukaryotic cells primarily takes place in two locations:
-
Cytoplasm: The initial stage of cellular respiration, glycolysis, occurs in the cytoplasm where glucose is broken down into pyruvate, generating a small amount of ATP.
-
Mitochondria: The subsequent stages of cellular respiration, namely the citric acid cycle (Krebs cycle) and oxidative phosphorylation (electron transport chain), occur in the mitochondria. This process produces the majority of ATP generated during cellular respiration.
Therefore, the correct answer is:
Cytoplasm and mitochondria.
