The correct answer is: Protons are pumped out of the mitochondrial matrix into the intermembrane space
Chemiosmosis can be described as movement of ions across a selectively permeable membrane, down their electrochemical gradient. It occurs during the cellular respiration within mitochondria and it is involved in ATP synthesis (oxidative phosphorylation via ATP synthase).
Electrons from electron carriers (NADH and FADH) donate electrons to the electron transport chain and that causes changes in protein complexes of electron transport chain. As a consequence, protein complexes pump H+ across a selectively permeable cell membrane from the mitochondrial matrix into the intermembrane space of mitochondria.
H+ can only get back and pass through the inner mitochondrial membrane with the help of ATP synthase (down their electrochemical gradient). ATP synthase turned by the force of the H+ diffusing through it forms ATP by adding a phosphate to ADP.
A. Separated twins develo traits that differ according to the environments in which they are raised
Nervous system and neuropipet compounds
Answer:
its most likely A, in sanitary landfills
Atoms bound together and form molecules. Molecules are a little more complex than atoms. For example water is composed of two hydrogen atoms and one oxygen atom which are both gases. Properties of oxygen and hydrogen are completely different than water molecules.
