5 Matching Questions

  1. What is a cellular metabolism?
  2. What stops molecules from spontaneously breaking down into less energetic molecules?
  3. What is this message-transfer process called?
  4. How does a receptor protein relay it's information?
  5. What is the problem with the concept of energy of activation?
  1. a It takes a very long time for all the products to gain enough energy to make it over the energy barrier
  2. b Every working cell in every organism caries out thousands of exer/endergonic reactions
  3. c The binding of the protein to the message sets off a chain reaction involving other proteins which relay the message to a meolecule that performs a specific activity inside the cell
  4. d The energy barrier
  5. e signl transduction

5 Multiple Choice Questions

  1. Doesn't bind to active sight, binds to corner of enzyme, changes shape of active sight so substrate cannot bind
  2. d
  3. The way of an plant/animal to prevent excessive uptake or excessive loss of water
  4. With one phosphate group and two fatty acids, has hydrophilic head and hydrophobic tails
  5. Most chemical reactions are organized into a series of steps, each catalyzed by an enzyme, to form certain product. If product is being over-made, then the product will act as an inhibitor to one of the enzymes in its pathway, called feedback inhibition (?)

5 True/False Questions

  1. Are inhibitors always harmful?No, enzyme inhibition often used for regulation cell metabolism


  2. What is a hypertonic solution?A solution whose pH is lower than that of the cells, cell gains water, pops


  3. Why is the structure of a phospholipid helpful and clever?Enzymes, and Because enzymes act as biological catalysts that increases the rate of a reaction without itself being changed into a different molecule, smushes down energy barrier


  4. What is energy coupling?The use of energy released from exergonic reactions to fuel necessary endergonic reactions


  5. What is an isotonic solution?A solution whose pH is equal to that of the cell, the cell gains water as quickly as it loses it, stays the same
