Aresearcher claims that the synthesis of atp from adp and inorganic phosphate (pi) is essential to cellular function.
which of the following statements best justify the researcher’s claim?
a. inorganic phosphate (pi) is a substance that cells typically acquire from their environment.
b. atp synthase is a mitochondrial enzyme that catalyzes the conversion of adp and pi to atp.
c. atp hydrolysis is an energy-releasing reaction that is often coupled with reactions that require an input of energy.
d. adp is a small molecule that some cells release into their environment as a way of communicating with other cells.
