Respiration

Question

Respiration releases energy...

Answer 1

because it's fun

Answer 2

to build up larger molecules (proteins) from smaller molecules (amino acids)

Answer 3

to allow muscles to contract in animals

Answer 4

so animals can maintain a constant body temperature

Answer 5

so plants can build sugars, nitrates and other nutrients into amino acids where they are then built into proteins

Answer 6

so we can breathe

Answer 7

some glucose is stored from food as glycogen

Answer 8

glucose breaks down into glycogen

Answer 9

glycogen is mainly stored in the liver

Answer 10

muscles have their own store

Answer 11

muscles use glucose vigorously during exercise so some of the glucose stored as glycogen is reconverted back into glucose for respiration

Answer 12

glycogen combines with oxygen in respiration

Answer 13

glucose -> lactic acid (+ a little energy)

Answer 14

glucose -> oxygen + lactic acid (+ a little energy)

Answer 15

glucose -> carbon dioxide + lactic acid (+ a little energy)

Answer 16

glucose -> lactic acid (+ a lot of energy)

Answer 17

you have to "repay" the oxygen that you didn't get to your muscles during exercise because your lungs couldn't keep up with the demand

Answer 18

you don't have any oxygen in your bloodstream

Answer 19

when you're suffocating

Answer 20

when you have such little oxygen in your muscles that they cannot work any longer

Answer 21

oxidising it to harmless CO2 and water

Answer 22

passing it out through the blood stream

Answer 23

breathing it out

Answer 24

waiting until your heartrate is normal

Answer 25

provided the energy required for protein synthesis

Answer 26

where protein synthesis takes place
