Q

Why does your heart rate increase when exercising?

A

blood pumping faster meaning more oxygen getting to blood and an increase in glucose meaning increase in energy released and more respiration.

Q

Anaerobic respiration is when there is not enough ____ present.

A

oxygen

17
Q

When overusing a muscle there is not enough oxygen present this leads to the production of….

A

lactic acid

18
Q

What is the word equation for anaerobic respiration in animals?

A

Glucose —-> lactic acid + energy

19
Q

What is the symbol equation for anaerobic respiration in animals?

A

C6H12O6 —-> 2C3H16O3 + 2ATP

20
Q

What is a cramp?

A

build up of lactic acid

21
Q

How is a cramp caused?

A

lack of oxygen to muscles

22
Q

How do you get rid of cramps?

A

by restoring the blood supply to the muscles

23
Q

Why does restoring blood flow relieve cramps?

A

more oxygen and glucose flowing to muscles.

able to switch back to aerobic respiration instead of anaerobic.

able to move lactic acid out of muscle cells.

24
Q

What does anaerobic respiration result in?

A

oxygen debt

25
Q

What does oxygen debt do?

A

the extra oxygen oxidises lactic acid to carbon dioxide and water.

26
Q

What is the word equation for oxygen debt or lactic acid whatever?

A

lactic acid + oxygen —-> carbon dioxide + water

27
Q

What is the word equation for anaerobic respiration in non-animals?

A

glucose —-> ethanol + carbon dioxide

28
Q

What is the symbol equation for anaerobic respiration in non-animals?

A

C6H12O6 —-> 2C2H5OH + 2CO2

29
Q

Lactic acid causes muscles to…

A

contract less

30
Q

What does EPOC stand for?

A

excess
post-exercise
oxygen
consumption

31
Q

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

A

glucose —> Ethanol + Carbon dioxide

32
Q

Why is anaerobic respiration useful in every day life?

A

it is used in yeast in the brewing industry. Ethanol is used for alcoholic drinks.

It is using in yeast in bread making.

33
Q

What is metabolism?

A

the sum of all the reactions in a cell or body.

34
Q

What are the 7 types of metabolism reactions?

A

Respiration.
Glucose —-> starch (in plants).
Glucose —-> cellulose (in plants).
Glucose —-> glycogen (in animals).
Formation of lipids from glycerol and fatty acids.
Use of glucose and nitrate ions to form amino acids for proteins.
Breakdown of excess protein into urea which is excreted.
