Verified step by step guidance

Understand the function of ATP synthase: ATP synthase is an enzyme that creates ATP (adenosine triphosphate) by using a proton gradient across the mitochondrial membrane.

Identify the location of ATP synthase: It is located in the inner mitochondrial membrane, where it facilitates the movement of protons (H+ ions) from the intermembrane space back into the mitochondrial matrix.

Recognize the role of protons (H+ ions): The movement of protons through ATP synthase is what drives the synthesis of ATP from ADP and inorganic phosphate.

Consider the size and charge of particles: ATP synthase is specifically designed to allow the passage of protons, which are small and positively charged, unlike larger molecules like glucose or charged particles like sodium ions.

Conclude that protons (H+ ions) are the particles that pass through the ATP synthase channel, as they are essential for the enzyme's function in ATP production.
