Question

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

fewer mitochondria since the transport proteins will also create ATP.
more mitochondria to meet the increased energy demand.
more mitochondria to repair damage to the ATP molecules.


fewer mitochondria since there will be fewer molecules left in the cell.

Answer 1

Since mitochondria are capable of replication,some workers think that once they are independent organism(bacteria). they got emtrapped in larger eukaryotic cells and become symbionts and then changed into their useful inseparable components due course in time. mitochondria are semiautonomous organelles. they are capable of self duplication(raplication). they have genetic information (DNA).protein making machinary (ribosomes). energy producing mechanism.
