Aerobic and Anaerobic Respiration Flashcards
1
Q
Which process in plants produces the glucose required for respiration?
A
Photosynthesis
2
Q
Is respiration an exothermic or endothermic reaction?
A
Exothermic
3
Q
examples of how cells use the energy from respiration (5)
A
- To combine small molecules to make larger molecules
- To break large molecules into smaller molecules
- For muscle contraction
- To maintain our body temperature
- To move substances around the cell
4
Q
What is metabolism?
A
The combination of all chemical reactions in an organism
5
Q
What is the word equation for respiration?
A
Glucose + oxygen ➔ carbon dioxide + water
6
Q
What is glucose converted to during anaerobic respiration in animals?
A
Lactic acid
7
Q
word equation for anaerobic respiration in plants and fungi:
A
Glucose ➔ ethanol + carbon dioxide
8
Q
What are the two reasons animals cells prefer aerobic respiration to anaerobic respiration?
A
- Anaerobic respiration doesn’t break down the glucose molecule completely, and so releases less energy than aerobic respiration
- Anaerobic respiration produces lactic acid which can damage cells and leads to an oxygen debt
