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!

one characteristic that is shared by all is a soft body. many

of these invertebrate animals also have an outer shell to protect their

body. oysters, clams, snails, and mussels are all mollusks. so are octopuses, squids, and slugs. mollusks live on land and in freshwater.
