Question

Why do plants make sugar from sunlight instead of just using ATP directly?(1 point)
Responses

ATP isn't very stable for long-term storage and is used quickly after it is made.

ATP only stores the energy in electrons, which are bound to the hydrogens, and transports it to many places.

ATP has less energy than sugars because it has an extra phosphate group.

ATP is only used to convert high-energy carbon molecules back to low-energy carbon molecules.

Answer 1

ATP isn't very stable for long-term storage and is used quickly after it is made.

Plants store energy as sugars (and starch) because these carbon compounds are much more stable and transportable for long-term storage; ATP is the short-term energy currency used immediately by cells.
