The generation of _______ occurs by chemiosmosis. DNA RNA NADP ATP
zavuch27 [327]

Answer;

ATP.

The generation of ATP occurs by Chemiosmosis.


Explanation;

In the electron transport chain, hydrogen ions in the matrix space can only pass through the inner mitochondrial membrane through a membrane protein called ATP synthase.

As these protons move through ATP synthase, ADP is turned into ATP.

The production of ATP using the process of chemiosmosis in mitochondria is called oxidative phosphorylation.
