What is the equation for aerobic respiration?
Glucose + Oxygen --> Carbon Dioxide + Water [+ energy]
1 of 13
Are the 4 main uses for energy from respiration?
1. Build larger molecules from smaller ones 2. Enable muscle contraction in animals 3. Maintain a constant body temperature 4. Build sugars, nitrates and other nutrients into amino acids and then proteins in plants
2 of 13
Where does aerobic respiration take place?
It takes place continually in plants and animals
3 of 13
Where in the cells does respiration take place?
The Mitochrondria
4 of 13
Why do the muscles need an increase in oxygen and glucose during exercise?
In order to create energy through respiration inoder for the muscle to contract
5 of 13
How does the body respond for the demand of oxygen and glucose during exercise?
1. Blood containing glucose and oxygen can travel around quicker as the heart beats faster and the blood vessels dilate 2. Your breathing rate and depth of breath increases to allow greater uptake of oxygen and release of Co2
6 of 13
What can glucose be converted to to be stored in muscles?
Glycogen
7 of 13
Why do muscles become fatigued?
1. They have too little oxygen 2.they been working for a long time. 3. Build up of latic acid
8 of 13
What is the equation for anaerobic respiration?
Glucose ---> Lactic Acid [+Little energy released]
9 of 13
How many energy is released in anaerobic respiration in comparison to aerobic respiration?
Less
10 of 13
How can you remove lactic acid?
Allowing the blood to flow through the muscles to remove lactic acid
11 of 13
Why is anaerobic respiration ineffective?
Because the breakdown of glucose is incomplete and lactic acid is produced as a waste product.
12 of 13
What is oxygen debt?
The extra oxygen needed to oxidise the lactic acid into carbon dioxide and water.
