Sam’s defective cytochrome b enzyme results in the malfunction of the mitochondrial system for

mitochondrial protein production.
DNA replication.
ATP synthetase.
electron transport.
The mitochondrial electron transport system moves electrons from a donor molecule to a receptor molecule, which in the process drives a proton (H+)H+ pump. In order to establish a proton gradient, the protons accumulate in

the matrix.
the intermembrane space.
the cristae.
How does the proton (H+)H+ gradient created by the electron transport system actually cause the production of ATP?
multiple choice 3
The retrograde flow through cytochrome b drives an ATP synthetase.
In order for the protons to flow back into the matrix of the mitochondrion, they must go through the ATP synthetase enzyme, and that flow provides the power to generate the ATP.
As we know from the reading, energy is conserved and can be converted from one form to another. Chemical energy from the food we eat is converted into a form of energy that is used in all cellular activity. That common form of energy is
multiple choice 4
AMP.
ATP.
