Q # 4 2..5
, In gluconeogenesis, organisms use ATP to make glucose, then in cellular respiration they break down the glucose
again to get energy. Why not just store the ATP? (Select all that apply.)
ATP does not have high-energy bonds.
ATP is not energy dense enough.
ATP only has energy after it is activated by
glucose.
ATP only has energy when it is attached to
glucose.
ATP is not stable enough.
ATP without a cofactor forms crystalline structures.
Using glucose directly to power enzymes is more efficient.
