Question

The electron transport chain is composed of adjacent electron carriers in the inner mitochondrial membrane. It generates energy by passing electrons from protein to protein, as shown by the yellow arrow.
This energy is then used to move hydrogen ions from the matrix through the protein complexes into the intermembrane space. Draw blue arrows to show the movement of hydrogen ions across the membrane. Cross off the hydrogen ions in the matrix and draw them in the intermembrane space.

Answer 1

Answer:Although protons resemble other positive ions such as Na+ and K+ in their movement across membranes, in some respects they are unique. Hydrogen atoms are by far the most abundant type of atom in living organisms; they are plentiful not only in all carbon-containing biological molecules, but also in the water molecules that surround them. The protons in water are highly mobile, flickering through the hydrogen-bonded network of water molecules by rapidly
