An organelle found in eukaryotic cells that is the site of aerobic respiration (13) 5. An enzyme found embedded in cellular membranes that phosphorylates ADP to form ATP as protons flow through it. (3, 8) 6. An organelle found in plants and algae that is the site of photosynthesis (12) 9. The membrane that segregates the thylakoid space from the stroma. It is the site of the electron transport transport chain (9, 8) 10. The space inside the membrane-bound thylakoid disks. Protons flow out of the thylakoid space across the thylakoid membrane (9, 5) Down 1. The fluid-filled space within the inner membrane of the mitochondria which contains mitochondrial DNA and enzymes required for aerobic respiration. Protons flow across the inner membrane into the matrix (6) 2. The fluid interior of chloroplasts that contain the enzymes required for the light-dependent reaction. Protons flow across the thylakoid membrane into the stroma (6) 4. An integral membrane protein that establishes a proton gradient for ATP synthesis across a membrane (6, 4) 7. The synthesis of ATP through the movement of protons down their concentration gradient across a semipermeable membrane, catalysed by ATP synthase. (12) 8. The small space between the inner and outer mitochondrial membranes. Protons flow out of the intermembrane space across the inner membrane (13, 5)
