Question 1

What is released during respiration?

energy

food

air

glucose

Question 2

Respiration is aerobic if it requires:

carbon dioxide.

energy.

oxygen.

lungs.

Question 3

Which of these is a correct word equation for respiration?

glucose + oxygen → carbon dioxide + water

carbon + dioxygen → glucose + oxygen

glucose → energy

oxygen + carbon → carbon dioxide

Question 4

The main difference between combustion and aerobic respiration is that:

only combustion releases energy by heating.

only respiration produces carbon dioxide.

only respiration produces water.

combustion is much faster.

Question 5

1 On the diagram, the part labelled with the letter X is the:

blood vessel.

oesophagus.

trachea.

bronchus.

Question 6

Heart disease is caused by:

the heart growing too big.

blood vessels leading to the heart muscle becoming blocked.

eating too much, which causes the stomach to push up on the heart.

being allergic to a certain substance in food.

Question 7

A poisonous substance in cigarette smoke stops red blood cells carrying oxygen. This substance is called:

tar.

nicotine.

water vapour.

carbon monoxide.

Question 8

How is carbon dioxide transported around the body?

carried on red blood cells

as a gas

carried on white blood cells

dissolved in the plasma

Question 9

During strenuous exercise:

the pulse rate increases so that oxygen can get to cells faster for respiration.

the pulse rate decreases to stop so much carbon dioxide getting to cells.

the pulse rate increases so that carbon dioxide can get to cells for respiration.

the pulse rate decreases so less carbon dioxide can get into the blood from respiring cells.

Question 10

10.

Aerobic respiration in plants:

is the same as in animals.

does not occur (plants use photosynthesis).

does not use glucose.

does not use oxygen.

Question 11

11.

When carbon dioxide is added to limewater:

the limewater turns from cloudy to clear.

the limewater turns from clear to cloudy.

the limewater turns green.

nothing happens.

Question 12

12.

The drawing shows the underside of a leaf. What are the parts labelled X called?

guard vessels

alveoli

stomata

cilia

Question 13

13.

Which organ do fish use for gas exchange?

lungs

skin

gills

mouth

Question 14

14.

Which substance does anaerobic respiration that humans & mammals only produce?

water

lactic acid

carbon dioxide

carbon monoxide

Question 15

15.

Anaerobic respiration can occur in a cell if there is a lack of:

oxygen.

water.

glucose.

nitrogen.

Question 16

16.

For each molecule of glucose, how much energy does anaerobic respiration release compared with aerobic respiration?

no energy.

more energy.

the same amount of energy.

less energy.

Question 17

17.

One cause of excess post-exercise oxygen consumption is:

an increased rate of anaerobic respiration after exercise.

aching muscles.

replacing stores of oxygen in the body.

being thirsty.

Question 18

18.

Explain an adaptation of the alveoli to allow gas exchange in humans.
