LIFESCI 7A Chapter Notes - Chapter 3: Reaction Rate, Enzyme, Homeostasis
Document Summary
Define and differentiate the terms anabolism and catabolism. Define and relate the terms kinetic energy, potential energy, and. Explain the first and second laws of thermodynamics. Define and relate the terms free energy, enthalpy, entropy, exergonic, chemical energy and endergonic exergonic reaction. Discuss how an endergonic reaction can be "coupled" to an. Define and relate the terms substrate, active site, activation energy, transition state, and reaction rate. Describe in general terms how enzymes are able to alter the rate of a chemical reaction. Explain how small molecules (e. g. , drugs or regulatory molecules) are able to increase or decrease the activity of an enzyme. Needed to do work, grow and divide, move, change shape, pump ions in and out, transport vesicles and synthesize macromolecules such as dna, rna, proteins, and complex carbohydrates. Adenosine triphosphate (atp) : molecule that provides energy in a form that all cells can readily use to perform the work of the cell.
