B4: Respiration Flashcards
What is anaerobic respiration?
When energy is released from glucose without oxygen
When does anaerobic respiration often happen in humans?
During intense exercise when we cannot take in enough oxygen
What is the word equation for anaerobic respiration in humans?
Glucose –> Lactic Acid + Energy
The special type of anaerobic respiration carried out by yeast is called…
…..fermentation
What is the equation for fermentation?
Glucose –> Ethanol + Carbon Dioxide (+ Energy)
What is yeast used for?
Making Beer
Making Wine
Making Bread
What is aerobic respiration?
When an organism releases energy from glucose by reacting it with oxygen.
List some reasons why humans need energy?
To keep warm
To move
To grow
To keep the body functioning
Where does the glucose that humans use in respiration come from?
Food (carbohydrates)
What is the word equation for aerobic respiration?
Glucose + Oxygen –> Carbon Dioxide + Water + Energy
How do our bodies get the oxygen needed for aerobic respiration?
We breathe in oxygen from the air
How are the waste products of aerobic respiration removed from the body?
Carbon dioxide (+ Water) are breathed out
Where does aerobic respiration happen?
Within the mitochondria of cells
Muscle cells carry out lots of aerobic respiration. Therefore they contain many…
mitochondria
How does glucose get into cells.
- Carbohydrate is eaten
- Carbohydrate is broken down into glucose in the small intestine.
- Glucose is absorbed into the blood plasma.4. Glucose exits the blood and enters the body’s cells.
