Cell respiration
by Alaiya Tucker
1. Building large molecules such as proteins
2. active transport of molecules and ions
3. Contraction of muscle cells producing movement
4. Why is oxygen used ?
4.1. Used to oxidise Food
5. Main food oxidize is glucose (as sugar)
6. Cells need a source of energy
7. Chemical energy can be used for variety of purposes such as
8. Yeast which is single celled
9. Example of anaerobic respiration
10. Definition
10.1. Source of energy,by breaking down food molecules to release the stores chemical energy
11. Aerobic respiration
11.1. Glucose + oxygen -> carbon dioxide +water(+energy)
11.2. Uses oxygen.
11.3. Release embers of the glucose in small amounts
11.4. Releases the most energy
12. Lactic acid
12.1. When glucose is broken down into a substance. When the blood cannot reach them fast enough to deliver enough oxygen fo aerobic respiration
12.2. Glucose -> lactic acid (+some energy)
