What is released during respiration?
Energy
Food
Air
Glucose
Respiration is aerobic if it requires:
carbon dioxide
energy
oxygen
lungs
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
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.
On the diagram, the part labelled with the letter X is the:
blood vessel.
oesophagus
trachea.
bronchus
During gas exchange in the lungs, there is an overall diffusion of:
carbon dioxide into the lung and oxygen into the blood.
oxygen into the lung and carbon dioxide into the blood.
oxygen and carbon dioxide into the blood.
oxygen and carbon dioxide into the lung.
During inhalation, rib and diaphragm muscles:
contract to increase the pressure inside the lungs.
relax to reduce the pressure inside the lungs.
contract to reduce the pressure inside the lungs.
relax to increase the pressure inside the lungs.
Dust is prevented from getting into the lungs by a layer of mucus, which is swept away by:
alveoli
cilia
filaments
flagella
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.
A poisonous substance in cigarette smoke stops red blood cells carrying oxygen. This substance is called:
tar.
nicotine.
water vapour.
carbon monoxide.
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
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.
Aerobic respiration in plants:
is the same as in animals.
does not occur (plants use photosynthesis).
does not use glucose.
does not use oxygen.
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.
The drawing shows the underside of a leaf. What are the parts labelled X called?
guard vessels
alveoli
stomata
cilia
Which organ do fish use for gas exchange?
lungs
skin
gills
mouth
Which substance does anaerobic respiration in humans produce?
water
lactic acid
carbon dioxide
carbon monoxide
Anaerobic respiration can occur in a cell if there is a lack of:
oxygen.
water.
glucose.
nitrogen.
Lactic acid is turned back into glucose, mainly in the:
lungs.
small intestine.
stomach.
liver
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.
