1. We breathe in
and breath out
2. Organisms need to eat because food is the source of
3. Cellular respiration may be classified into two types, aerobic if it is
and anaerobic if it is
where a molecule of
4. An anaerobic respiration also begins with
glucose is broken down into two molecules of
4. In anaerobic respiration, acetaldehyde acts as the acceptor of hydrogen to
produce a molecule of
5. The broken down of molecules consist of three steps, namely glycolysis,
and Krebs cycle.
7. Glycolysis occurs in
8. Pyruvate oxidation and Krebs cycle occurs in
9.
Cellular respiration cannot take place in the absence of
10. Pyruvic acid oxidation converts pyruvic acid into
with the
production of carbon dioxide.​
