| W |
Cells require energy in order to fulfill their function. |
|
Why do cells require energy? |
|
|
| T |
All cells obtain energy through respiration. |
|
How do cells obtain energy? |
|
|
| A |
Most respiration happens in the mitochondria of a cell. |
|
Where in a cell does most respiration happen in a cell? |
|
|
| T |
Respiration is the decomposing (breaking down) of large particles which contain lots of energy into smaller particles containing less energy.
The extra energy is released from the chemical reaction is used by the cell. |
|
What is respiration in terms of particles? |
|
|
| T |
Respiration is an exothermic reaction. |
|
In terms of energy, what type of reaction is respiration? |
|
|
| W |
For respiration cells need Glucose (sugar) and oxygen. |
|
What do cells need for respiration? What do we need, so that we can do exercise? |
|
|
| W |
Most animals and plants do respiration using oxygen. This is called aerobic respiration. |
|
What is the most common type of respiration in plants and animals? How are aerobic classes different from weight lifting?

|
|
| T |
Aerobic respiration can be represented as
Glucose plus Oxygen => Carbon Dioxide plus Water ( plus Energy ) |
|
What is the word equation for aerobic respiration? |
|
|
| T |
When there isn't enough oxygen, cells can't do aerobic energy.
Instead cells do anaerobic respiration. |
|
Why do cells switch the type of respiration they are doing? |
|
|
| T |
Anaerobic respiration can be represented as
Glucose => Lactic acid ( plus Energy ) |
|
What is the word equation for anaerobic respiration? |
|
|
| T |
Anaerobic respiration releases less energy than aerobic energy. |
|
Why do most plants and animals do aerobic respiration, rather than anaerobic? Why can't people keep on lifting heavy weights for a long time?
- Car is not getting heavier.
- Muscles are not getting smaller.
- They can take a break, without eating anything and then start again.

|
|
| T |
Lactic acid causes a burning sensation in the muscle and possibly cramps. |
|
What effect does Lactic acid have? |
|
|
| W |
To get rid of the Lactic acid, it must be combined with oxygen to convert it back into water and carbon dioxide. |
|
How do we get rid of Lactic acid? Why do people continue to breathe heavily after exercise? |
