Cell Bio - Aerobic Respiration Flashcards
1
Q
What is respiration?
A
The cellular process of releasing energy from food through a series of enzyme-controlled reactions
2
Q
What is respiration used for in mammals?
A
Mammals need to release heat energy from food to keep their body temperature close to the optimum temperature for their enzymes to work.
3
Q
Name the two types of respiration
A
- Aerobic Respiration
- Fermentation
4
Q
What is the word equation for AEROBIC RESPIRATION in plant, animal and fungal cells?
A
glucose + oxygen → carbon dioxide + energy + water
5
Q
How much ATP is produced from aerobic respiration?
A
A lot
6
Q
Where does stage one and stage two of aerobic respiration occur?
A
Stage one: cytoplasm
Stage two: mitochondria
7
Q
Explain the process of aerobic respiration
A
S1: Cytoplasm
- Glucose is broken down to 2 molecules of pyruvate = releases enough energy to make 2 molecules of ATP. (no oxygen needed)
S2: Mitochondria
- A pyruvate molecule enters the mitochondria, makes carbon dioxide and water
- releases enough energy to make lots of ATP. (oxygen needed)
8
Q
Aerobic respiration is controlled by…
A
Enzymes
