Chapter 4 Cellular Energetics Vocabulary Bioenergetics- The study of how cells release and store energy that is packed in the chemical bonds holding the molecules together. Enzymes- Organic catalysts that speed up the rate of a reaction without altering the reaction itself. Organic catalysts- consist of carbon, hydrogen and sulfur and other nonmetal elements found in organic compounds. Exergonic reactions- Energy is given off in an exergonic reaction. The energy of the products have less energy than the reactants. E.g, when food is oxidized in mitochondria of cells and energy that is stored in the chemical bonds is released. Endergonic reactions- Energy is gained in an endergonic reaction. The energy of the products is more than that of the reactants. E.g, plants use CO2 and water to form sugars. Activation energy- The energy required for a reaction to take place. Enzymes lower activation energy. Enzyme specificity- Each enzyme only catalyzes one type of reaction.
