What is respiration? |
When chemical energy stored in food(glucose) is released by all living cells through a series of enzyme controlledreactions called respiration |
|
|
What is the name of the energy form which is generated in respiration? |
ATP |
|
|
ATP must be built up from this during respiration and then broken back down into this when used. |
ADP + Pi |
|
|
Give 2 examples of the use of ATP in cellular activities. |
Muscle contractions, cell division, protein synthesis, transmission of nerve impulses, photosynthesis. |
|
|
What are the two types of respiration? |
Aerobic and fermentation (anaerobic) |
|
|
What controls respiration? |
enzymes |
|
|

|
|
What does aerobic respiration mean? |
Oxygen is present |
|
|
What does fermentation (anaerobic respiration) mean? |
No oxygen is present |
|

|
|
During fermentation (anaerobic) in animals, what is the final product in stage 2? |

|
|
Where does fermentation take place in the cell? |
The cytoplasm |
|
|
How many ATP molecules are produced during fermentation? |
2 ATP |
|
What is piece of equipment known as? |
A respirometer |
|
What would this equipment be measuring? |
The rate of oxygen uptake during aerobic respiration. |
|
What would this piece of equipment be measuring in respiration? |
The amount of energy in the form of heat being produced during respiration. |
