Which of the following is true about plants and cellular energy

B.

Plants use light energy to produce food molecules during photosynthesis and obtain cellular energy from the bonds of these food molecules during cellular respiration.

The chlorophyll pigment in plants harnesses light energy to ‘manufacture’ glucose/carbohydrates which are later used by the plant for cellular respiration to power cell activities.

Explanation:

The energy from sunlight is used by the chlorophyll pigments to make ATPs through a process called photophosphorylation. In addition, the light energy is used to split  water molecules into H⁺  and O²⁻. The H⁺ is then captured by NADP+ which is reduced to NADPH, while O²⁻ is evolved as oxygen. This occurs in the light stage of photosynthesis.

The NADPH is used to reduce carbon dioxide into glucose in the dark stage (Calvin cycle) of photosynthesis. Remember since this is an anabolic process ATPs (the one created through photophosphorylation) are used to power this cycle.

Excess glucose can be converted to starch and stored. Otherwise, the energy captured in the chemical bonds of the glucose are again utilized to make ATPs in cellular respiration.

i have to report this, it doesn't relate to biology

i'm sorry, but can you list the answers? i cannot with something i don't know the answers to
