5 Written Questions

1. Enzyme: Maltase
2. an inorganic ion helper for enzymes to function properly; metals such as copper, zinc, or iron
3. Loss of normal shape by an enzyme so that it no longer functions, may happen when temperature is too high
4. protene that functions to speed a chemical reaction, not used up by the reaction
5. Enzyme: Urease

5 Matching Questions

1. entropy
2. Energy
3. More Organized
4. Substrate: Lipid
5. Enzyme Inhibition

1. a ability to do work or bring about change, majority of organisms get energy from photosynthesizers
2. b relative amount of disorganization
3. c occurs when substrate is unable to bind to the active site of an enzyme
4. d less stable--always has potential to become less organized
5. e Enzyme: LIpase

5 Multiple Choice Questions

1. an organic but nonprotein helper for enzymes to function properly
   1. Energy
   2. Coenzyme
   3. Cofactor
   4. Enzyme
2. stored energy--its capacity to accompish work is not being used at the moment ex: the food we eat has potential energy
   1. Potential Energy
   2. Mechanical Energy
   3. Chemical Energy
   4. Kinetic ENergy
3. spontaneous and release energy
   1. Endergonic Reactions
   2. Coupled Reactions
   3. Redox Reaction
   4. Exergonic Reactions
4. applies to living systems; energy cannot be changed from one form to another without a loss of usable energy; every energy transformation makes universe less organized and more disordered
   1. Cellular Respiration
   2. Secon d Law of Thermodynamics
   3. Induced fit model
   4. First Law of Thermodynamics
5. the change in shape an active site has to accomodate substrate(s) in order to get optimum fit
   1. Anabolism
   2. Reduction
   3. Induced fit model
   4. Active Site

5 True/False Questions

1. Anabolism → breaking down of molecules

   True        False

2. Substrates → reactants in an enzymatic reaction

   True        False

3. Cellular Respiration → energy released by an exergonic reaction is used to drive an endergonic reaction

   True        False

4. First Law of Thermodynamics → explains why energy flows in ecosysctems and cells; the law of conservation of energy;energy cannot be created or destroyed, but it can be changed from one form to another

   True        False

5. Metabolism → sum of all the chemical reactions that occur in a cell

   True        False
