Question

question 2 matching consider the geography or anatomy of glucose metabolism. prompts ① the etc of aerobic cellular respiration makes use of the _. ② glycolysis occurs in the _. ③ the krebs cycle occurs in the ___. answers matrix cytoplasm intermembrane space

Explanation:

1. The electron - transport chain (ETC) of aerobic cellular respiration occurs in the inner mitochondrial membrane and uses the proton gradient across the inner mitochondrial membrane. But among the options, it makes use of the intermembrane space for the proton - motive force generation.
2. Glycolysis is the first step of cellular respiration and occurs in the cytoplasm of the cell.
3. The Krebs cycle, also known as the citric acid cycle, occurs in the mitochondrial matrix.

Answer:

1. intermembrane space
2. cytoplasm
3. matrix
