B
In the nucleus during DNA replication
C
In lysosomes during macromolecule degradation
D
On the inner mitochondrial membrane (cristae) by ATP synthase during oxidative phosphorylation
Verified step by step guidance1
Recall that ATP production in eukaryotic cells primarily occurs during aerobic respiration, which involves multiple stages including glycolysis, the citric acid cycle, and oxidative phosphorylation.
Understand that glycolysis happens in the cytoplasm and produces a small amount of ATP, but the majority of ATP is generated later in the process.
Recognize that the citric acid cycle takes place in the mitochondrial matrix, producing electron carriers that feed into the electron transport chain.
Identify that the electron transport chain is located on the inner mitochondrial membrane (cristae), where a proton gradient is established.
Know that ATP synthase, an enzyme embedded in the inner mitochondrial membrane, uses this proton gradient to synthesize most of the cell's ATP during oxidative phosphorylation.
