- Respiration GCSE
- Aerobic Respiration (uses oxygen)
- A series of reactions where energy is released from glucose
- glucose + oxygen = carbon dioxide + water
- Most of the reactions involved occur in the mitochondria
- Anaerobic Respiration
- This may occur during exercise as not enough oxygen reaches the muscles to carry out aerobic respiration
- This results in an incomplete breakdown of oxygen
- Muscles become fatigued during exercise due to lactic acid
- glucose = carbon dioxide + water
- Lactic acid is removed by blood flowing through
- Less energy is produced by anaerobic respiration
- This is because glucose isn't completely broken down
- It causes an oxygen debt
- More oxygen is needed to oxidise lactic acid to carbon dioxide + water
- How the energy from Respiration's used:
- To build up larger molecules from smaller ones
- To enable animals muscles to contract, so they are able to move
- To keep there body at a constant temperature
- For instance if surroundings are too cold
- Exercise
- During exercise a lot more energy i9s required
- Glucose and oxygen are used up a lot more quickly
- Oxygen is supplied more quickly to meet this demand by increased heart rate/ breathing rate
- Plants store glycose as starch
- Animals store glucose as glycogen
