question 6
the citric acid cycle occurs in the:
stroma
mitochondrial matrix
mitochondrial membranes
cytoplasm
thylakoid membranes

Explanation:

The citric acid cycle, also known as the Krebs cycle, is a key metabolic pathway in cellular respiration. It occurs in the mitochondrial matrix. The stroma is related to chloroplasts (involved in photosynthesis). Mitochondrial membranes are associated with the electron - transport chain (for ATP synthesis via chemiosmosis). The cytoplasm is where glycolysis occurs. Thylakoid membranes are part of chloroplasts (site of light - dependent reactions in photosynthesis).

Answer:

mitochondrial matrix
