1

What is anaerobic respiration?

When energy is released from glucose without oxygen

2

When does anaerobic respiration often happen in humans?

During intense exercise when we cannot take in enough oxygen

3

What is the word equation for anaerobic respiration in humans?

Glucose --> Lactic Acid + Energy

4

What are the products of anaerobic respiration in humans?

Lactic Acid + Energy

5

What is the reactant of anaerobic respiration in humans?

Glucose

6

Why do you continue breathing after intense exercise?

The extra oxygen is needed to break down lactic acid

7

What do we call the extra oxygen needed to break down lactic acid after intense exercise?

The oxygen debt

8

Why does the body normally respire aerobically?

It releases more energy from glucose
It does not produce lactic acid which causes cramps

9

What does lactic acid do to the muscles?

Causes cramps

10

When might a plant respire anaerobically?

If its roots are waterlogged so cannot get oxygen.

11

The special type of anaerobic respiration carried out by yeast is called...

fermentation

12

What is yeast?

A microorganism (fungi)

13

What is fermentation?

A type of anaerobic respiration done by yeast

14

What is the equation for fermentation?

Glucose --> Ethanol + Carbon Dioxide + Energy

15

What are the products of fermentation?

Ethanol + Carbon Dioxide + Energy

16

What is yeast used for?

Making Beer
Making Wine
Making Bread

17

How is yeast used to make bread?

Flour, water and yeast are mixed together.
Yeast ferments the sugar in the dough.
Ethanol and Carbon Dioxide gas are released
The gas is trapped in the dough and makes it rise
