|
|
Mitochondria are storage sites for molecules which move by active transport
|
|
|
Mitochondria produce the carrier proteins
|
|
|
Mitochondria release energy, which is needed for active transport
|
|
|
None of the above
|
Detailed explanation-1: -Mitochondria is more prevalent in cells where active transport occurs more frequently. Mitochondria is the site of respiration in cells, therefore more energy will be released.
Detailed explanation-2: -Another important example of active transport is the mitochondrial electron transport chain, which is based on reduction of NADH. It moves protons across the mitochondrial membrane from lower to higher concentration. This generates energy used to power life.
Detailed explanation-3: -Active transport occurs in cells with many mitochondria in order to provide sufficient energy for this process to occur.
Detailed explanation-4: -A vital active transport process that occurs in the electron transport process in the membranes of both mitochondria and chloroplasts is the transport of protons to produce a proton gradient. This proton gradient powers the phosphorylation of ATP associated with ATP synthase.
