Where is the Majority of ATP Generated in Prokaryotic Cells

Question

Where is the majority of ATP generated in prokaryotic cells?
A) in the cytoplasmic membrane
B) in the cytosol
C) in the thylakoids
D) in the inner mitochondrial membrane
E) on ribosomes

Accepted Answer

In prokaryotic cells, the majority of ATP is generated in the cytoplasmic membrane through the process of oxidative phosphorylation. The electron transport chain is embedded in the membrane, and as electrons are passed along the chain, protons are pumped out of the cell, creating a gradient. This gradient is then used by ATP synthase to generate ATP.
