Question

Energy captured during the photo part of photosynthesis is stored ____________ during the synthesis part of the process.

A. in carbon atoms AND in covalent bonds
B. as high-energy electrons
C.as high-energy electrons AND in covalent bonds

Answer 1

During photosynthesis, energy is stored as high-energy electrons and in the covalent bonds of sugar molecules, like glucose, enabling long-term energy storage.

Step-by-step explanation:

Energy captured during the photo part of photosynthesis is stored as high-energy electrons and in covalent bonds during the synthesis part of the process. In the light-dependent reactions, sunlight energy is absorbed and used to energize electrons, storing this energy in molecules such as ATP and NADPH.

When these molecules release their energy into the Calvin cycle, they help form the covalent bonds of sugar molecules like glucose. These covalent bonds in carbohydrates represent the stable long-term storage of energy, which can last for millions of years, as evidenced by the energy now released from fossil fuels like coal and petroleum.
