Respiration
- Aerobic respiration
- Oxygen + glucose --> carbon dioxide + water (+energy)
- Requires oxygen
- Is the release of
energy in cells by the
breakdown of food
substances in the
presence of oxygen
- Happens in both animals and plants
- Produces energy in the form of ATP
- Why do we respire?
- We respire to get energy. We need energy for:
- Cell divsion
- Growth
- Muscle contraction
- Active transport
- Protein synthesis
- Nerve impulses
- Anaerobic respiration
- glucose --> lactic acid
- Far less efficient that aerobic respiration
- Happens duing hard
exercise or whenever there
is no oxygen
- The build up of lactic acid causes oxygen
debt. We keep breathing heavily after
exercise to get out of oxygen debt
- Less ATP is produced
- Lactic acid is harmful to the body so it has to be removed
from cells. This happens once aerobic respiration begins
