Which biological process involves the conversion of one type of chemical energy into another type of chemical energy? a. cellular respiration b. transpiration c. photosynthesis d. active transport

A is the correct answer. Transpiration is water moving through a plant, photosynthesis is the conversion of solar energy into chemical energy, and active transport is the movement of molecules across a cell membrane into an area of higher concentration, so none of those are right. Cellular respiration is the only one of those four that converts chemical energy (glucose) is converted into another type of chemical energy (adenosine triphosphate).
