Answer 2

Energy efficiency

Explanation:

The overall efficiency of energy conversion if one mole of ATP is formed per two equivalents of electron excited by red light is as follows:

1. The energy efficiency of photosynthesis is the ratio of the energy stored to the energy of light absorbed.
2. The chemical energy stored is the difference between that contained in gaseous oxygen and organic compound products and the energy of water, carbon dioxide, and other reactants.
3. The amount of energy stored can only be estimated because many products are formed, and these vary with the plant species and environmental conditions.
4. If the equation for glucose formation given earlier is used to approximate the actual storage process, the production of one mole (i.e., 6.02 × 1023 molecules; abbreviated N) of oxygen and one-sixth mole of glucose results in the storage of about 117 kilocalories (kcal) of chemical energy. This amount must then be compared with the energy of light absorbed to produce one mole of oxygen in order to calculate the efficiency of photosynthesis.
