Read the following statements regarding the locations of respiratory events in a eukaryotic cell: A. Glycolysis occurs in the cytoplasm of the cell. B. The enzymes of the citric acid cycle are located in the intermembrane space of mitochondria. C. The electron transport system is present in the outer mitochondrial membrane. D. During oxidative phosphorylation, a proton gradient is formed by the accumulation of proton

Step-by-step solution

Statement A is correct as glycolysis occurs in the cytoplasm of all living organisms. Statement B is incorrect because the enzymes of the citric acid cycle are primarily located in the mitochondrial matrix, not the intermembrane space. Statement C is incorrect because the electron transport system (ETS) is located in the inner mitochondrial membrane. Statement D is incorrect because during oxidative phosphorylation, protons are pumped into the intermembrane space, leading to their accumulation there, not in the mit
