A
Mitochondrial intermembrane space.
B

검증된 단계별 안내1
Understand the structure of the mitochondria: It consists of an outer membrane, an intermembrane space, an inner membrane, and the matrix.
Recognize the role of the electron transport chain (ETC): It is located in the inner mitochondrial membrane and is responsible for creating a proton gradient.
Identify the movement of H+ ions: As electrons pass through the ETC, energy is used to pump H+ ions from the mitochondrial matrix across the inner membrane.
Determine the destination of the H+ ions: The H+ ions are pumped into the intermembrane space, creating a high concentration of protons there.
Conclude the purpose of this process: The proton gradient established across the inner membrane is used to drive ATP synthesis as H+ ions flow back into the matrix through ATP synthase.
