All organisms require energy in order to function. This energy comes from a variety of sources, but all energy on earth originated in the sun. Energy is neither created nor destroyed, it is just transformed. All living things transfer energy between them. Photosynthesis is the process of converting light energy into chemical energy.

Enzymes are biological catalysts that are made of protein. The specific pattern of amino acids that make up an enzyme determines its three-dimensional shape and the substrate that it will act upon. The three-dimensional shape of an enzyme forms an active site. This site is where the substrate, or molecule that the enzyme acts upon, binds to the enzyme.

3.1 Enzyme Structure

A catalyst is a substance that increases the rate of a reaction. An enzyme is a biological catalyst, a specific subcategory. Enzymes function by decreasing the activation energy necessary for a reaction to occur. This can be shown in the graph below. As portrayed, the energy associated with reactants and products of the reaction does not change due to the presence of the enzyme.

All organisms require the input of energy in order to facilitate metabolic processes. All energy originates with the sun. This energy is converted into cellular energy by photosynthetic organisms. This energy can then be broken down further into the most basic form of cellular energy, adenosine triphosphate, ATP.

3.4 Cellular Energy

Photosynthesis is a chemical process with the following equation: H2O + CO2 → C6H12O6 + O2. Both plants and photosynthetic bacteria are capable of this complex conversion process. The overall reaction is spurred by the energy from a photon of light striking a pigment in the chloroplast.

Cellular Respiration is a chemical process with the following equation: C6H12O6 + O2 → H2O + CO2. All organisms, including those capable of photosynthesis, go through the process of cellular respiration. The overall reaction breaks down a carbohydrate, most frequently modeled by glucose, and converts the energy stored in that molecule into the most basic cellular energy, ATP.
