Define anabolism.
Your Answer:
Anabolism is the building up of macromolecules from smaller molecular units into more complex molecules.Anabolism is the process of building up or biosynthesis of macromolecules from small molecular units into much larger complexes.
Upon cellular injury, which metabolic process is involved during the growth and repair phases of the cell?
Your Answer:
Anabolism The anabolic process would be active as it (by definition) is involved in the building up of small complexes into larger complexes.
Describe the energy transfer process relative to both ATP and ADP.
Your Answer:
ATP has the energy to donate a phosphate group and ADP is able to accept a phosphate group. ATP is being reduced and ADP is being made into ATP.ATP has the energy (phosphate group) to donate while ADP can accept energy in the form of a phosphate group. Thus, ATP can be reduced (ATP ⟶⟶ADP + Pi) while ADP can be built into ATP (ADP + Pi ⟶⟶ATP).
