In the electron transport chain, atp synthase is responsible 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

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!

the peripheral nervous system or pns contains the nerves, which leave the brain and the spinal cord and travel to certain areas of the body. the peripheral nervous system's main job is to send information gathered by the body's sensory receptors to the cns as quickly as possible.
