Q

What is respiration

A

The process of transferring energy from glucose

17

A

To build larger molecules, to allow muscles to contract, keep body temperature steady

18
Q

What is metabolism

A

All the chemical reactions in an organism

Glucose + oxygen ————— carbon dioxide + water

21
Q

What is the symbol equation for aerobic respiration

A

C6H12O6 + 602 ——————— 6CO2 + 6H2O

22

What is the word equation for anaerobic respiration in plants and yeast cells

A

Glucose ———————— ethanol + carbon dioxide

26
Q

What is anaerobic respiration in yeast cells called

A

Fermentation

27
Q

What does anaerobic respiration lead to

A

An oxygen debt

28
Q

What are two effects of exercise on the body

A

Increased breathing rate and increased heart rate

29
Q

How can you measure the effects on the body

A

For breathing rate you can count the number of breath before and after exercise and for heart rate check pulse before and after exercise
