Question

In the electron transport chain, ATP synthase is responsible for... a. pumping hydrogen ions against concentration gradient b. producing chemiosmotic gradient inside the matrix c. adding a phosphate group to adp d. capturing oxygen and connecting it with free hydrogen ions

Answer 1

Hey there!

Your answer is C, adding a phosphate group to ADP.

The chemical reaction would be ADP + Pi -----> ATP, where ATP synthase is the enzyme that catalyzes the reaction.

Using "synthase" in the name of a protein means that the enzyme is used to synthesize a molecule. For example, "citrate synthase" synthesizes the citrate molecule. Therefore, ATP synthase synthesizes ATP.

Hope this helps!
