Enzymes are proteins that act as catalysts for reactions, such as those in cellular respiration. They increase the likelihood of a reaction by lowering the energy required for a reaction to occur. In the process, enzymes are left unchanged by the reaction. They may stress bonds in a molecule and increase the chance of that bond breaking and they may force molecules or atoms together and help in the formation of a new bond. The molecules that bind to the enzyme are called substrates.

Living organisms require a continuous input of energy to maintain cellular and organismal functions such as growth, repair, movement, defense, and reproduction. Cells can only use chemical energy to fuel their functions, therefore they need to harvest energy from chemical bonds of biomolecules, such as sugars and lipids. Autotrophic organisms, namely plants, algae, and photosynthetic and chemosynthetic bacteria, convert inorganic materials into such biomolecules by harnessing energy from the environment, such as from sunlight during photosynthesis. Heterotrophic organisms are unable to synthesize high-energy biomolecules from inorganic materials, so they obtain energy by consuming carbon compounds produced by other organisms, primarily from autotrophs. When energy is needed, chemical bonds of carbon compounds are broken to harvest the energy stored in these bonds.

Which of the following occurs in both photosynthesis and respiration?
