The electron micrograph shows part of a cell including a mitochondrion.
Outline how the structures labelled X and Y are adapted to carry out the function of the mitochondrion.
X: Y:
X: large/increased SA area for ATP production/electron transport/oxidative phosphorylation/proton pumping OR X: small/narrow intermembrane space for generating proton gradient (rapidly/steeply); Y: contains enzymes for Krebs cycle/link reaction;
