Answer:
B
Explanation:
In heat transfer and thermodynamics, a thermodynamic system is said to be in thermal contact with another system if it can exchange energy through the process of heat. Perfect thermal isolation is an idealization as real systems are always in thermal contact with their environment to some extent
Adenosine triphosphate(ATP) transfer energy by doing phosphorylation. ATP has three phosphate molecule and it will release one phosphate when releasing energy(exergonic reaction), become ADP + P. ADP could be reused by catching energy(endergonic reaction), makes them catch a phosphate molecule and reform into ATP.
