BIOLOGY TEST REVIEW: Test #2b Metabolic Processes1.Metabolismenergy:The ability to do work.Metabolism:The sum of all anabolic and catabolic processes in a cell or organism.catabolic reaction:Reactions that break molecules into their individual subunits.anabolic reaction: Reactions that produce large molecules from smaller subunits.kinetic energy:Energy possesed by moving objects.potential energy:Stored energyWork:The transfer of energy from one body or place to anotherbond energy:The minimun energy required to break one mole of bonds between teo speciesof atoms; a measure of the stability of a chemical bond.activation energy:the difference between the energy level of the transition state and thepotential energy of the reacting molecules.exothermic reaction:When energy is given off in a reaction.Endothermic reaction:When energy is absorbed in a reaction.Entropy:The measure of the randomness or disorder of energy or in a collection of objects2.Redox Reactions-oxidation and reductionOxidation: A chemical reaction when an atoms loses one or more electronsReduction: A chemical reations in which an atoms gains one or more electrons.importance of such reactionsredox reactions are important because they are the principal sources of energy on this planet,both natural or biological and artificial.examples of such reactions?3.Condensation and Hydrolysis Reactions-definitions and examplesCondensation reaction:an anabolic reaction in which two molecules combine to form a largermolecule, producing a small molecule such as H2O as a byproductHydrolysis reaction:a catabolic reaction in which a water molecule is used to breaka acovalent bond holding subunits together.-be able to draw these reactions for all the macromolecules and for ADP/ATP?? Not apart of this unit?4.EnzymesEnzymes:a substance produced by a living organism that acts as a catalyst to bring about aspecific biochemical reaction.
5.The Structure of the MitochondriaSize and shape-round or sausage-shapes organellesStructure: outer membrane, inner membrane, intermembrane space, matrix-They are made of two membranes.-The outer membranecovers the organelle and contains it like a skin.-The inner membranefolds over many times and creates layered structures called cristae.The fluid contained in the mitochondria is calledthe matrix.-Intermembrane spaceis the fluid filled space between the inner and outer membranes.6.Glycolysis-know glycolysis in as much detail as is in the notes we took-the overall equation of glycolysis (what goes in and what comes out)-first 10 reactions in cell respiration are collectively called glycolysis-Glucose is converted into pyruvate-Overall, the process of glycolysis produces a net gain of two pyruvate molecules, two ATPmolecules, and two NADH molecules for the cell to use for energy.
