What is respiration
|
Respiration is a series of reactions in which energy is released from glucose.
|
|
|
What is aerobic respiration and what is its equation?
|
Aerobic respiration is the form of respiration which uses oxygen. It can be summarized by the equation:
glucose + oxygen → carbon dioxide + water (+ energy) |
|
|
Where does aerobic respiration happen?
|
Aerobic respiration happens all the time in the cells of animals and plants. Most of the reactions involved happen inside mitochondria, tiny objects inside the cytoplasm of the cell. The reactions are controlled by enzymes.

|
Using energy
|
During exercise, the muscle cells respire more than they do at rest. This means that:
- Oxygen and glucose must be delivered to them more quickly This is achieved by increasing the heart rate, rate of breathing and the depth of breathing. -Waste carbon dioxide must be removed more quickly |
|
|
How does the increased heart rate affect your body.
|
The increased heart rate increases the rate of blood flow around the body. The increased rate and depth of breathing increases the rate of gaseous exchange in the lungs.
|
|
|
How do the muscles store glucose?
|
The muscles store glucose as glycogen. This can then be converted back to glucose for use during exercise.
|
|
|
What is anaerobic respiration?
|
Anaerobic respiration is a type of respiration that does not use oxygen. It is used when there is not enough oxygen for aerobic respiration.
|
|
|
What is the equation for anaerobic respiration?
|
Glucose ----->Lactic acid + Energy
