Flashcards in B1.3.3 - Anaerobic Respiration Deck (10):
1

When would you need anaerobic respiration?

Exercise

2

Why does anaerobic respiration need to occur?

When you exercise, your heart rate will increase in rate. However, it cannot exceed its maximum rate so it transfers energy from chemical stores using anaerobic respiration

3

What is the word equation for anaerobic respiration?

Glucose -> lactic acid

4

What is produced in anaerobic respiration?

Poisonous lactic acid

5

Why do humans normally respire aerobically?

Aerobic respiration produces more ATP molecules per glucose molecule.
Anaerobic respiration produces lactic acid which can cause cramps and fatigue

6

What is oxygen debt?

The extra oxygen you inhale after anaerobic respiration to break down lactic acid

7

What organisms does anaerobic respiration occur in?

Many different animals and plants, sometimes microorganisms

8

What does anaerobic respiration in microorganisms and plants produce?

Ethanol and carbon dioxide

9

What is fermentation?

The process of ethanol and carbon dioxide getting made during anaerobic respiration in plants and microorganisms

10

What is the word and symbol equation for fermentation?

Glucose -> ethanol + carbon dioxide
C6H12O6 -> 2C2H5OH + 2CO2
