Biology - Respiration

Question 1

Cellular respiration

Answer 1

An exothermic reaction which is continuousaly occurring in living cells

Question 2

What does the energy transferred in respiration supply?

Answer 2

The energy transferred supplies all the energy needed for living processes

Question 3

Aerobic respiration equation

Answer 3

glucose + oxygen —> carbon dioxide + water (+ energy release)

Question 4

Glucose chemical symbol

Answer 4

C6H12O6

Question 5

Oxygen chemical symbol

Answer 5

O2

Question 6

Carbon dioxide chemical symbol

Answer 6

CO2

Question 7

Water chemical symbol

Answer 7

H2O

Question 8

Which respiration process has oxygen?

Answer 8

Aerobic respiration

Question 9

Which respiration process doesn’t have oxygen?

Answer 9

Anaerobic respiration

Question 10

Anaerobic respiration equation in muscles

Answer 10

Glucose —> Lactic acid

Question 11

How does the oxidation of glucose affect respiration?

Answer 11

As the oxidation of glucose is incomplete in anaerobic respiration, much less energy is tranferred than in aerobic respiration

Question 12

Effects of excercise

Answer 12

The heart rate, breathing rate and breath volume increase during exercise to supply the muscles with more oxygenated blood. This enables increased cellular respiration so more energy is transferred to meet the demands of the muscle cells.
