A.) when a catalyst is added

The answer is a because a catalyst (or an enzyme) lowers the amount of energy required for the reaction to begin, therefore, it can happen quicker.

protons are pumped across the mitochondrial inner membrane as electrons are transferred through the mitochondrial electron trans
Ipatiy [6.2K]

If the facts about proton pumping are true, then protons are pumped into the matrix of the mitochondria.

<h3>What causes the electron transport chain's proton pumping?</h3>

Proton pumps are found in the electron transport chain's complexes I, III, and IV. The complexes absorb the energy generated when electrons migrate energetically downward and use it to pump H +start superscript, plus, end superscript ions out of the matrix and into the intermembrane gap.

<h3>when outside of the Matrix are protons pumped?</h3>

At complexes I, III, and IV, the matrix is pumped of protons (2 per complex). The resultant proton gradient drives ATP synthesis: 2 H+ are generated for every ATP. The inner mitochondrion is charged differently due to the proton gradient.
