Cellular Respiration
For the following questions refer to the internet link about cellular respiration.
1. Cellular respiration - the process where chemical bonds of glucose (sugar) are
converted into energy.
2. In respiration, the process of
materials in many different steps.
3. First,
enzymes
oxidation
occurs by breaking down
(or proteins) are released during oxidation.
4. Then, enzymes convert the
energy in the form of ATP.
5. The release of ATP happens in
pyruvates.

(or sugar) into small amounts of
steps: glycolysis and the breakdown of
For the following 2 questions refer to the internet link about glycolysis.
6. Glycolysis, a process during cellular respiration, is a procedure that does not need
oxygen
in any of its steps.
7. What three things happen in the plants’ cytoplasm during glycolysis?

It is the process that converts on molecule of glucose into two molecules of
pyruvate.

It releases energy in the form of two molecules of ATP.

It takes place in the cytoplasm of the plant.
For the following questions refer to the internet link about the Kreb’s cycle and
electron transport chain.
8. Two carbon molecules from the pyruvate carry very
energy
9. The energy rich electrons are used to make a lot of energy, or
rich electrons.

For the following questions refer to the internet link about cellular respiration.
10. The two molecules of pyruvate (which came from 1 molecule of glucose) are broken
down in
2
ways: through aerobic respiration and anaerobic respiration.
11. Aerobic respiration requires
oxygen
12. Anaerobic respiration does not require

13. During aerobic respiration, the pyruvate breaks down into what three things?
a. ATP molecules
b. carbon dioxide
c. water
14. Aerobic respiration takes place in the
mitochondria
of the cells.
15. During anaerobic respiration, the pyruvate only partially breaks down through what 2
things?
a. fermentation
b. lactic acid fermentation
16. During anaerobic respiration, the pyruvate partially breaks down through
fermentation into what three things?
a. ethenol
b. carbon dioxide
c. water
17. During anaerobic respiration, the pyruvate also partially breaks down through lactic
acid fermentation into what three things?
a. lactic acid
b. carbon dioxide
c. water
