Unit 2: The Cell An Introduction to Metabolism Review
  1. consists of all the reactions of a living organism. These reactions are organized into metabolic .
     
     
     
     
  2. Energy is associated with the relative of objects, and abides by laws of physics called .
     
     
     
     
     
     
     
     
    Review: Energy Transformations
     
     
     
     
  3. ATP drives chemical reactions for cellular work by , transferring a phosphate to other molecules, and is replenished by cellular (aerobic) .
     
     
     
     
  4. An is a protein that speeds up a reaction without being consumed by the reaction.
     
     
     
     
  5. An enzyme facilitates an reaction by lowering its energy.
     
     
     
     
  6. The enzyme is activated when its substrate binds to the protein's site, and can be inhibited by the binding of other molecules.
     
     
     
     
  7. Enzymes must be in the proper 3-dimensional (conformation) to be active. Factors that affect enzyme function include and pH, and most enzymes have an optimal temperature and pH range.
