In an energized molecule directly adds a phosphate group to adp, but uses a concentration gradient of protons as the energy source required to phosphorylate adp.

phosphorylation; ATP

Explanation:

Phosphorylation is the name of one of the processes that occur in mitochondria during cellular respiration. With phosphorylation, cells gain a reservoir of energy for metabolic activities. In this process electron transfer from electronic donors to electronic acceptors occurs. This transfer is the redox reactions that enable the process of energy release, biologically usable for ATP biosynthesis.

In this case, an energized molecule would add a phosphate group to the ADP for ATP formation. However, ATP would use a proton gradient as the energy source needed to phosphorylate ADP.

the element that provides strength to the exoskeletons of clams and oysters is phosphorus.

this is so because calcium carbonate is the main component in the shells. calcium carbonate is strengthened by phosphorus.

explanation:

several tissues working together form an organ, and several organs together make up an organisms.

the group of cell that carries out special jobs are tissue.
