| Interactions between molecules within the orderly enviornment of the cell. | ||
| Release energy--breaking down BIG molecules to small molecules. Cellular Respiration. Glucose broken down to Carbon Dioxide & water like Sugar Glucose. | ||
| Consume energy -- build complex molecules from SMALL TO BIG. ~synthesis of a protein from amino acids. | ||
| exergonic process to drive an energonic one. | ||
| A chemical agent that changes the rate of a reaction w/o being consumed by a reaction. | ||
| protein serving as a catalyst. | ||
| (Free Energy Of Activation) the initial investment of energy for starting a reaction -- the energy required to break bonds in the reactant molecules. | ||
| The reactant on which an enzyme works. | ||
| a pocket or groove on the surface of a protein. | ||
| "A clasping handshake." When the substrate squeezes into the enzyme. | ||
| Lowers activation energy & speeds up a reaction. | ||
| The initial investment of energy necessary to start a chemical reaction. | ||
| nonspontaneous, (endergonic/endothermic) reaction | ||
| spontaneous (exergonic/exothermic) reaction | ||
| ATP (Adenosine Triphosphate) |
