Respiration Flashcards
1
Q
Aerobic respiration formula
A
Oxygen (O2) + Glucose (C6 H12 O6) -> Carbon Dioxide (CO2) + Water (H2O)
2
Q
What do both types of respiration produce ?
A
Energy
3
Q
Anaerobic respiration formula
A
Glucose -> Lactic acid + Energy
4
Q
What is the site of gaseous exchange ?
A
Alveoli
5
Q
Adaptations of Alveoli
A
- Moist walls
- Permeable walls (One cell thick)
- Good blood supply
- Large surface area
6
Q
Respiration definition
A
The chemical release of energy
7
Q
What is the difference between aerobic and anaerobic respiration?
A
- Anaerobic respiration is the process of respiring with the absence or lack of oxygen
- Aerobic respiration is respiring with the presence of oxygen in the surrounding environment.
- Anaerobic respiration also produces a bi-product called lactic acid.
8
Q
What does lactic acid cause ?
A
- Lactic acid causes a fatigue in muscles.
- (This is because of the incomplete break down on glucose due to the lack of oxygen in a surrounding environment)
9
Q
What are the benefits of anerobic respiration ?
A
- Anaerobic respiration allows organisms to survive in surrounding environments which lack the presence of oxygen.
-Anaerobic respiration is also much faster than aerobic respiration
10
Q
What is the structure of the respiration system ?
A
Nasal Cavity / Mouth
Pharynx
Larynx
Trachea
Bronchi
lungs
Bronchioles
Alveoli
Diaphragm
11
Q
What is the name of the site of gaseous exchange ?
A
Alveoli
12
Q
What are the benefits of aerobic respiration ?
A
- Aerobic respiration releases a high amount of energy
- Provides energy for other processes in the body (e.g. cell devision and protein synthesis which helps growth and repair and muscle contraction which is required for movement)
