Final answer:
The Krebs cycle and Electron Transport Chain (ETC) do not take place in the cytoplasm, but rather in the mitochondria. The cytoplasm is where glycolysis occurs.
Step-by-step explanation:
False, the Krebs cycle and the Electron Transport Chain (ETC) do not occur in the cytoplasm. The Krebs cycle takes place in the matrix of the mitochondria, while the ETC is located in the inner mitochondrial membrane. The cytoplasm is where the glycolysis process happens, which is the first step of cellular respiration. Here, glucose is broken down into pyruvate. The products of this reaction then move into the mitochondria for the Krebs cycle and ETC.
