|
|
What is energy used for? |
To power chemical processes in all life forms. |
|
|
What is the formula for aerobic respiration? |
Oxygen + Glucose —> Water + Carvon dioxide (+energy) |
|
|
What is the name of respiration without oxygen? |
Anaerobic respiration |
|
|
What is anaerobic respiration? |
As well as restwithout oxygen, it involves the break down of glucose to create energy. |
|

|
|
What is the equation for fermentation? |
Glucose —> Alcohol + Carbon dioxide (+energy) |
|
|
How can Fermentation be effected? |

|
|
What are the lungs? |
The organ used for breathing and gas exchange. |
|
|
How does oxygen get to the lungs? |
It diffuses into the blood through the alveoli to the lungs. |
|
|
How does carbon dioxide escape from our body? |
It is breathed out after the carbon dioxide diffuses from the blood into the alveoli. |
|
|
What happens when we breathe in air? |
The chest inflates The ribs move up and out The diagphram moves down The air pressure in the lungs decreases Air is forced inside the lungs |
|
|
What happens when we breathe out? |
The chest deflates The ribs move down and in The diagphram moves up The pressure in the lungs increases The air in the lungs is forced out |
|
|
Why is gas exchange effective in the lungs? |
The alveoli has a large surface area, it is mpist and thin and has a good blood supply. |
|
|
What affects our breathing? |
Exercise, asthma and smoking |
|
|
How do plants obtain their gases? |
Through the stomata in the leaf for photosynthesis and respiration. |
|
|
What is the stomata? |
The holes beneath the leaf that are opened and closed by guard cells to allow carbon dioxide, oxygen and water vapour to enter and exit the leaf. |
