Question 6
Not yet graded / 10 pts
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).
