Can h+ pass through cell membrane

WebFeb 1, 2024 · The fatty acid tails being non-polar in nature repel any polar or charged particle and hence don't allow them to enter the cell or escape out of it. The other factor that contributes is the larger size of ions. The smaller molecules, e.g. C2H 5OH instead of being polar, get their way into the cell by passing through these phospholipid bilayers ... WebSo basically in mitochondria one pair of H+ produces 1 ATP. In other words due to movement of 2 protons across the membrane of mitochondria ; conformational change in F1 part results in synthesis of 1 ATP molecule from ADP + Pi. whereas in chloroplast 3 H+ produce 1 ATP. That is movement of 3 protons across lumen to stroma through CF1 …
