Question 4


pts


Define anabolism.



Your Answer:


Anabolism is the building up or biosynthesis of smaller molecules into larger, more complex
macromolecules. Anabolism is growth and repair



Anabolism is the process of building up or biosynthesis of macromolecules
from small molecular units into much larger complexes.




Question 5

pts


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.




Question 6


pts


Describe the energy transfer process relative to both ATP and ADP.



Your Answer:


ATP has the energy to donate a phosphate group to ADP and ADP has the ability to recieve
phosphate from ATP.



Essentially, ATP is ADP plus Phosphate



ATP has the energy (phosphate group) to donate while ADP can accept energy
in the form of a phosphate group. Thus, ATP can be dephosphorylated (ATP
