When a cell has to endure lasting changes in its environment that require it to actively transport more molecules than normal through the cell membrane, what effect will this have on the mitochondria of the cell? the cell will need a)fewer mitochondria since the transport proteins will also create atp. b)more mitochondria to meet the increased energy demand. c)more mitochondria to repair damage to the atp molecules. d)fewer mitochondria since there will be fewer molecules left in the cell.

I believe the answer is option B. but don't hold me to it. Hope it helps

b) more mitochondria to meet the increased energy demand.

Explanation:

ATP is the utmost necessity during active transport because unlike passive transport active transport moves the substances against the concentration gradient. In passive transport, molecules move from a higher concentration to a lower concentration until the concentration of the molecule becomes equal on both the sides of the membrane. Such cell is said to be in equilibrium with the environment. It is a natural process which does not require any energy input. In contrast to this in active transport, the molecule moves from lower concentration to higher concentration which is reverse of the natural law and therefore require energy input from outside source. Mitochondria is the powerhouse of cell because it helps in meeting energy demands of our body by producing ATP through cellular respiration. So, in order to meet more demand of active transport more ATP will be required and more ATP means more mitochondria requirement in the cell.
