Question

Select the correct statement about chemical energy, a term used by biologists to refer to potential energy available for release in a chemical reaction. When a glucose molecule is metabolized to CO2 and H2O, chemical energy is lost. Light energy is converted to chemical energy during photosynthesis. A photosynthetic cell within a plant leaf produces chemical energy, stored within glucose molecules

Answer 1

Light energy is converted to chemical energy during photosynthesis

Step-by-step explanation:

Light energy in the form of photons is harnessed by a protein chain molecule in photosystems (I & II) in the chlorophyll pigments of plants. This energy is used to split a water molecule and the subsequent H+ are used to reduce CO2 into carbohydrates. Therefore, this light energy is stored in the chemical bonds of glucose and carbohydrates. This energy is thereafter used in cellular respiration where these bonds are broken and the energy used to make ATPs (the energy currency molecule of the cell).
