Answer:

B.It causes cells to change and specialize.

Explanation:

In the cellular differentiation  a cell changes from one cell type to another. Generally, the cell changes to a more specialized type. Differentiation occurs numerous times during the development of a multicellular organism as it changes from a simple zygote to a complex system of tissues and cell types forming a complete organism. Cellular differentiation occurs through gene expression. In this process cells become specialized in order to perform different functions.

For example generic embryonic cells become blood cells  and nerve cells.

Options

A. Yes, because all enzymes and electron carriers are functional

B. No, because with a leaky membrane, the proton gradient cannot be maintained

C. No, because leaky membranes inhibit glycolysis

D. No, because leaky membranes do not allow NADH and FADH2 to donate their electrons to the electron transport chain

Answer:

B. No, because with a leaky membrane, the proton gradient cannot be maintained

Explanation:

The proton motive force (PMF) provides the needed pump  to generate electrochemical gradients of proton needed for continue influx  into the matix of the mitochondria. The proton Influx generates the energy needed by  protein ATPase Synthase for  synthesis  of ATPs by adding inorganic phosphate to ADP to give ATP.

               ADP + Pi -----------→ ATP.

If the mitochondria;l  intramembrane leaks, then the PMF can  not be sustained, therefore electtrochermical gradient which supplies the energy for ATP synthase for ATP synthesis will not be available. Therefore ATP synthesis stops.
