How and where is ATP made in a eukaryotic cell?
A. ATP is made in all compartments of the cell in response to endergonic reactions and is used to drive exergonic reactions in the cell. B. ATP is only made in the mitochondria in response to chemiosmosis. C. 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. D. 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.
