  1. 1The cell needs energy to do [blank_start]work[blank_end]. [blank_start]Energy coupling[blank_end] allows exergonic processes (which [blank_start]release[blank_end] energy) to be coupled with endergonic processes (which [blank_start]absorb[blank_end] energy) so that every necessary process is facilitated.
    1. Awork
    2. BEnergy coupling
    3. Crelease
    4. Dabsorb
  2. 2Which process is ATP NOT involved in?
    1. ANeurotransmission
    2. BRNA synthesis
    3. CTransport
    4. DCell linking
  3. 3Select the equation which BEST outlines the exergonic process of ATP hydrolysis.
    1. AATP → ADP + Phosphate group + Energy
    2. BATP → ADP + PO3 + ATP
    3. CADP + Phosphate group + Energy → ATP
    4. DADP → ATP
  4. 4ATP hydrolysis does not change the energy of a system, but rather creates free energy for another process.
    1. AVerdadero
    2. BFalso
  5. 5ATP phosphorylates molecules which would not normally react and allows endergonic processes to occur.
    1. AVerdadero
    2. BFalso
  6. 6ATP hydrolysis cools the surrounding environment.
    1. AVerdadero
    2. BFalso
  7. 7ATP is recyclable.
    1. AVerdadero
    2. BFalso
  8. 8Which statement about the ATP cycle is CORRECT?
    1. AATP hydrolysis forms ADP and a phosphate group, as well as producing free energy for endergonic processes
    2. BATP will readily reform from ADP and a phosphate group while free floating in the cytoplasm.
  9. 9Fermentation is a [blank_start]catabolic[blank_end] process to attain chemical energy from food [blank_start]anaerobically[blank_end].
    Cellular respiration is a catabolic process to attain [blank_start]chemical energy[blank_end] from food [blank_start]aerobically[blank_end], mainly from [blank_start]glucose[blank_end] in starch and carbohydrates.
    1. Acatabolic
    2. Banabolic
    3. Cchemical energy
    4. Dmechanical energy
    5. Eaerobically
    6. Fanaerobically
    7. Gglucose
  10. 10Which of the following statements about cellular respiration is CORRECT?
    1. ACellular respiration harvests energy from C-H bonds by transferring the electrons to O2.
    2. BCellular respiration harvests energy from C-H bonds and transfers the electrons to O2.
    3. CCellular respiration harvests energy from C-H bonds by transferring the electrons to an electron carrier like NAD.
