What is the equation for aerobic respiration? |
Oxygen + Glucose → Water + Carbon Dioxide |
|
|
What is the symbol equation for aerobic respiration? |
C6H12O6 + 6O2 → 6CO2 + 6H2O |
|
|
What is the test for CO2? |
Lime water turns cloudy. |
|
|
Why do men need more food? |
Because they generally have bigger body structures and use more energy. |
|
|
True or False? Anaerobic respiration creates more energy than aerobic respiration. |
FALSE |
|
|
Where is glucose stored? |
Glucose is stored in the liver, then is converted back to glucose when exercising for more energy. |
|
|
Where does aerobic respiration happen? |
In the mitochondria. |
|

|
|
Why do we breathe more frequently when we exercise. |
Because we require more oxygen to be pumped around our body and get rid of more excess carbon dioxide. |
|
|
What is the equation for anaerobic respiration? |
Glucose → Lactic Acid (+ energy into the environment) |
|
|
What is the symbol equation for anaerobic respiration. |
C6H12O6 → C3H6O3 |
|
|
Where does anaerobic respiration happen? |
The Cytoplasm. |
|
|
What is oxygen debt. |
After exercise, oxygen is still needed to breakdown lactic acid. Oxygen debt is the amount of oxygen needed. |
|
|
What is lactic acid? |
A colourless syrupy organic acid produced in the muscle tissues during strenuous work. |
|
|
How does anaerobic respiration work and produce energy? |
Anaerobic respiration transfers energy from glucose to cells and occurs when oxygen is not present. It transfers lots of energy quickly. |
|
|
How does aerobic respiration work and produce energy? |
Aerobic respiration turns fuels such as sugar and fats into energy and makes more energy than anaerobic respiration. |
|
|
What does anaerobic respiration produce in some plants and microorganisms? |
Ethanol and carbon dioxide. |
|
|
What is a stitch? |
When there is a reduction of blood supply in the diaphragm causing it to cramp. |
|
|
Contraction |
When a muscle shortens. |
|
|
Why are there lots of mitochondria in muscle cells? |
Because lots of energy is used and must be produced in the muscle cells. |
|
|
What organ system gets glucose from food. |
Digestive System |
|
|
Why is respiration constant even when we're asleep? |
Because we are always breathing and pumping oxygenated blood around the body. |
|
|
Name some effects of exercise. |
Aching muscles; fast pulse; dehydrated; stitch; lose weight; sweat; red skin; heavy breathing; light headed/tired. |
