Respiration Flashcards
1
Q
Aerobic Respiration
A
The release of energy from food using oxygen
2
Q
Aerobic Respiration Process
A
- Glucose breaks down
- ATP formed
(Controlled by enzymes)
3
Q
Products of Aerobic Respiration
A
- Carbon Dioxide
- Water
- Energy
4
Q
Role of Aerobic Respiration
A
- Produce ATP
- Maintain body temp
5
Q
Glycolosis (Stage 1 Aerobic)
A
- Oxygen not involved
- Involves enzymes
- Glucose converted to 2 pyruvates
(products: Small ATP, NADH, CO2
6
Q
Krebs Cycle (Stage 2 Aerobic)
A
- Pyruvate breaks down into Acetyl
- Large amount of ATP made
- NADH formed
- CH+ & electrons combine with NAD+
7
Q
Electron Transport System
A
- Takes place in mitochondria
- NADH supplies electrons to form ATP
- Electrons combine with hydrogen & oxygen to form water
- Excess energy turns to heat in the system
8
Q
Anaerobic Respiration
A
The release of energy from food (no oxygen needed)
9
Q
Anaerobic Respiration Process
A
- Stage 1: Glycolysis
- If oxygen not present after stage 1, pyruvate can’t enter mitochondria (converts to other product)
10
Q
Advantages & Disadvantages of Anaerobic Respiration
A
Advantages:
1. Helps organisms in low oxygen environments
2. Provides extra energy when demand is higher
Disadvantages:
1. Inefficient - Small ATP yield
2. Products are toxic
