5 Written questions

5 Matching questions

  1. How are enzymes like assembly lines?
  2. What is feedback inhibition?
  3. What is induced fit?
  4. How does it switch to ADP?
  5. What is the plasma membrane?
  1. a The bonds that keep the three phosphates together are easily broken by hydrolysis, when the bond to the third group breaks the phosphate group leaves ATP which becomes ADP, and energy is released (?)
  2. b A product from one catalyctic cycle becomes the substrate for the next, and so on down a chain of enzymes
  3. c Forms a boundary between the living cell and its surroundings and controls the traffic of molecules into and out of the cell, takes up substances the cell needs and disposes of the cells wastes
  4. d 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. e When the active sight changes slightly to bind more tightly to the substrate

5 Multiple choice questions

  1. Many poisons, pesticides, and drugs
  2. A chemical reaction that releases energy, reactants covalent bonds contain more energy than products
  3. Lipids, mostly phospholipids
  4. The way cells release energy, chemical process that uses oxygen to convert the chemical energy stored in fuel molecules to form chemical energy that the cell can use to perform work
  5. The use of energy released from exergonic reactions to fuel necessary endergonic reactions

5 True/False questions

  1. Why are plants healthier in hypotonic environments?Because plants have cell walls which make it harder for the solution to take effect, need more of it

          

  2. What is ATP?Adenosine Triphosphate, powers nearly all forms of cellular work

          

  3. Are inhibitors always harmful?A specific reactant that an enzyme reacts on, fits into the active sight

          

  4. What is osmosis?Adenosine Triphosphate, powers nearly all forms of cellular work

          

  5. What is a cellular metabolism?The way cells release energy, chemical process that uses oxygen to convert the chemical energy stored in fuel molecules to form chemical energy that the cell can use to perform work
