1. cellular respiration
2. glycolysis
3. aerobic respiration
4. anaerobic respiration
5. mitochondrion
6. krebs cycle
7. alcoholic fermentation
8. electron transport chain
9. lactic acid fermentation

a. the first step of cellular respiration that takes place in the cytoplasm and produces a net of 2 molecules of atp for every one molecule of glucose
b. the general type of cellular respiration that occurs when no oxygen is present
c. general process that breaks down glucose to produce atp
d. the type of anaerobic respiration that occurs in animal cells
e. the general type of cellular respiration that occurs in the mitochondria when oxygen is available to a cell
f. the step in aerobic respiration that produces 36 molecules of atp for every one molecule of glucose
g. the type of anaerobic respiration that occurs in plant cells
h. the step in aerobic respiration that produces 2 molecules of atp for every one molecule of glucose
i. the cell organelle where aerobic respiration takes place

Explanation:

To solve this matching problem, we analyze each term related to cellular respiration and fermentation:

1. Cellular Respiration: The general process of breaking glucose to make ATP (matches C).
2. Glycolysis: First step in cytoplasm, 2 ATP per glucose (matches A).
3. Aerobic Respiration: Occurs with oxygen, in mitochondria (matches E).
4. Anaerobic Respiration: Occurs without oxygen (matches B).
5. Mitochondrion: Organelle for aerobic respiration (matches I).
6. Krebs Cycle: Step in aerobic respiration, 2 ATP per glucose (matches H).
7. Alcoholic Fermentation: Anaerobic in plant cells (matches G).
8. Electron Transport Chain: Step in aerobic respiration, 36 ATP per glucose (matches F).
9. Lactic Acid Fermentation: Anaerobic in animal cells (matches D).

Answer:

1. C. general process that breaks down glucose to produce ATP
2. A. the first step of cellular respiration that takes place in the cytoplasm and produces a net of 2 molecules of ATP for every one molecule of glucose
3. E. the general type of cellular respiration that occurs in the mitochondria when oxygen is available to a cell
4. B. the general type of cellular respiration that occurs when no oxygen is present
5. I. the cell organelle where aerobic respiration takes place
6. H. the step in aerobic respiration that produces 2 molecules of ATP for every one molecule of glucose
7. G. the type of anaerobic respiration that occurs in plant cells
8. F. the step in aerobic respiration that produces 36 molecules of ATP for every one molecule of glucose
9. D. the type of anaerobic respiration that occurs in animal cells
