Respiration

Question 1

what is respiration?

Answer 1

Respiration is the process of releasing energy from glucose, which goes on in every cell

Question 2

what is the equation of aerobic respiration?

Answer 2

Glucose + oxygen —–> Carbon dioxide + water +energy

Question 3

what is the equation for anaerobic respiration?

Answer 3

Glucose —–> energy + lactic acid

Question 4

what is the energy from respiration used for in BOTH animals and plants?

Answer 4

To build up larger molecules from smaller ones (proteins and amino acids)

Question 5

what do animals use energy from respiration for?

Answer 5

For muscle contraction and to keep body temperature the same

Question 6

what do plants use energy from respiration for?

Answer 6

To build up sugars, nitrates and nutrients to make amino acids then protiens

Question 7

why does exercise increase the heart rate

Answer 7

Exercise increases the heart rate as you need to pump more blood with oxygen around to the muscles so that aerobic respiration can take place or to repay the oxygen ‘debt’ left by anaerobic respiration

Question 8

what is glycogen?

Answer 8

Glycogen is converted glucose stored in the muscles for extra energy during vigorous exercise
