Multiple Choice

How and where is ATP made in a eukaryotic cell?

• A)ATP is only made in the mitochondria in response to chemiosmosis.
• B)ATP is made in all compartments of the cell in response to endergonic reactions and is used to drive exergonic reactions in the cell.
• C)ATP can be made by direct phosphorylation of ADP in the cytoplasm,and by an enzyme complex that uses the energy from a proton gradient to drive ATP synthesis in the mitochondria.It can also be made in other locations in the cell,depending on the cell type.
• D)ATP can be made by an enzyme complex that uses the energy of protons moving down their concentration gradient from the mitochondrial matrix to the cytoplasm to make the ATP.
