Answer: I think positive electrical charge
Explanation: Water molecules have a polar arrangement of the oxygen and hydrogen atoms—one side hydrogen has a positive electrical charge and the other side oxygen had a negative charge. This allows the water molecule to become attracted to many other different types of molecules.
Answer:
Energy released by the electron transport chain is used to pump H+ into <em>the mitochondrial intermembrane space</em> - Option D-.
Explanation:
There exist three proteinic complexes immersed in the internal mitochondrial membrane. These complexes have the electron transporters and the enzymes necessary to catalyze the electron transference from one transporter to the other. In complexes, I and III released energy by electrons provokes changes in membrane transport protein conformation. These changes make possible the protons transport against their concentration gradient, going from the mitochondrial matrix toward the intermembrane space. The protons concentrations difference between the matrix and the intermembrane space represents released energy.
Answer:
Because it is inevitable and no one truly knows what to expect from it.
