Question

part 1 - vocabulary matching
match each term to the correct definition by writing the letter in the blank.

1. __ calorie
2. __ cellular respiration
3. __ aerobic
4. __ anaerobic
5. __ glycolysis
6. __ nad+
7. __ krebs cycle
8. __ matrix
9. __ fermentation
10. __ synthesize

definitions:
a. process that requires oxygen.
b. unit of energy; the amount needed to raise the temperature of 1 gram of water by 1°c.
c. molecule that carries electrons during glycolysis and respiration.
d. breakdown of glucose into pyruvic acid in the cytoplasm.
e. process of combining smaller parts into a new whole (e.g., atp molecules).
f. the inner compartment of the mitochondrion where the krebs cycle occurs.
g. energy - releasing process that does not require oxygen.
h. produces carbon dioxide, nadh, fadh2, and atp inside the mitochondrion.
i. the process that releases energy by breaking down glucose in the presence of oxygen.
j. regenerates nad+ in the absence of oxygen so glycolysis can continue.

Explanation:

1. A calorie is a unit of energy. The amount needed to raise the temperature of 1 gram of water by 1°C. So 1 - B.
2. Cellular respiration is the process that releases energy by breaking down glucose in the presence of oxygen. So 2 - I.
3. Aerobic means a process that requires oxygen. So 3 - A.
4. Anaerobic means an energy - releasing process that does not require oxygen. So 4 - G.
5. Glycolysis is the breakdown of glucose into pyruvic acid in the cytoplasm. So 5 - D.
6. NAD+ is a molecule that carries electrons during glycolysis and respiration. So 6 - C.
7. The Krebs cycle produces carbon dioxide, NADH, FADH2, and ATP inside the mitochondria. So 7 - H.
8. Matrix is the inner compartment of the mitochondrion where the Krebs cycle occurs. So 8 - F.
9. Fermentation regenerates NAD+ in the absence of oxygen so glycolysis can continue. So 9 - J.
10. Synthesize means the process of combining smaller parts into a new whole. So 10 - E.
