D.It provides a safe place for offspring to grow.
Explanation:
The survival of offspring is crucial, especially in the bird world.If you lose offspring, there will be no future for your kind because you lost the new ones.
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.
