Read the wording for your board, then hide it and explain Proton gradient in your own words. Rough notes are fine. This is a self-check, with no mark or grade.
Reference: OCR
Energy from electron transport pumps protons across the inner mitochondrial membrane from the matrix into the intermembrane space, creating a gradient.
Built as energy from electron transfer is used to pump protons from the matrix into the intermembrane space.
