Vedclass · Answer

(B) The figure shows the $F_0-F_1$ particle ($ATP$ synthase) located in the mitochondrial inner membrane.$ATP$ synthesis occurs through chemiosmosis,which is driven by a proton gradient.Protons $(H^+)$ flow from the intermembrane space (outside) into the mitochondrial matrix (inside) through the $F_0$ channel of the $ATP$ synthase complex.This flow of protons provides the energy required for the phosphorylation of $ADP$ to $ATP$ in the $F_1$ headpiece.Therefore,$P$ represents the flow of protons $(H^+)$.

The following figure is a diagrammatic representation of $ATP$ synthesis in mitochondria. What is $P$ in it?
