Respiration

Question 1

when does aerobic respiration take place

Answer 1

it occurs all the time

Question 2

when does anaerobic respiration take place

Answer 2

when there is a lack of oxygen

Question 3

where does aerobic respiration take place

Answer 3

Mitochondria

Question 4

where does anaerobic respiration take place

Answer 4

in the muscles

Question 5

what is the word equation for aerobic respiration

Answer 5

oxygen + glucose - Carbon dioxide + water + Energy

Question 6

what is the order once trachea is split

Answer 6

Trachea, Bronchi, Bronchioles, Alveoli

Question 7

“the particles move to the capillaries” what is this process called

Answer 7

diffusion

Question 8

what is diffusion

Answer 8

The movement of particles from a low concentration to a high concentration

Question 9

what is glycogen

Answer 9

a store of glucose in the liver

Question 10

what happens to the blood vessels - Vasodilation

Answer 10

the widening of blood vessels

Question 11

what happens to the blood vessels - Vasoconstriction

Answer 11

the narrowing of blood vessels

Question 12

what is metabolism

Answer 12

the sum of all the reactions in the body

Question 13

name the three words that must be used in an exam.

Answer 13

oxidise, release, diffusion

Question 14

what is the equation of anaerobic respiration

Answer 14

glucose —- lactic acid

Question 15

what is the equation for anaerobic respiration in plants and yeast

Answer 15

glucose —- ethanol + carbon dioxide

Question 16

why is respiration important

Answer 16

respiration is the process of transferring energy from glucose which goes on in every cell.

you need energy to keep your body going

Question 17

what happens to the body during anaerobic respiration exercise

Answer 17

when you do vigorous exercise your body cannot supply enough oxygen to your muscles

therefore the muscles start to anaerobic respirate as well as aerobic respiration

anaerobic respiration is the incomplete breakdown of glucose making lactic acid and a small amount of energy

it does not transfer nearly as much energy as aerobic respiration

during exercise it allows your to keep on using your muscles for a while longer

Question 18

how is anaerobic respiration by yeast useful

Answer 18

because it can be used in fermentation,

in the food and drink industry can be used in beer and Bread

in bread making its the carbon dioxide from fermentation which makes the bread rise

in beer and wine making its the fermentation process that produces alcohol

Question 19

what is muscle fatigue

Answer 19

when the muscles get tired and then stop contracting efficiently

Question 20

what is oxygen dept

Answer 20

the amount of extra oxygen your body needs to react with the build up of lactic acid and remove it from the cells.

oxygen reacts with lactic acid to form harmless CO2 and water

Question 21

how is the liver involved in repaying the oxygen dept

Answer 21

the second way of coping with high levels of lactic acid is,

the blood that enters your muscles transports the lactic acid to the liver

in the liver the lactic acid is converted back to glucose
