The anaerobic reactions of cellular respiration occur in the _____, whereas the aerobic reactions of cellular respiration occur in the ______. A) mitochondria with O₂ required; cytoplasm with O₂ required B) cytoplasm without O₂ required; cytoplasm with CO₂ required C) mitochondria without O₂ required; mitochondria with O₂ required D) cytoplasm without O₂ required; mitochondria with O₂ required

Question

Quizplus · Accepted Answer

The anaerobic reactions of cellular respiration, such as glycolysis, occur in the cytoplasm without requiring oxygen. The aerobic reactions of cellular respiration, such as the Krebs cycle and electron transport chain, occur in the mitochondria, where oxygen is used as the final electron acceptor. Therefore, the best choice is D – cytoplasm without O₂ required; mitochondria with O₂ required.
