Respiration (Year 8)

What is the word equation for aerobic respiration?

• glucose + oxygen → lactic acid + energy

• glucose → lactic acid + energy

• glucose + oxygen → carbon dioxide + water + energy

• glucose → carbon dioxide + water + energy

What occurs during anaerobic respiration?

• Energy is released using oxygen

• Energy is released without using oxygen

• Energy is stored in glucose

• Energy is released using carbon dioxide

What are tiny air sacs found at the end of bronchioles in your lungs called?

• Veins

• Arteries

• Alveoli

• Capillaries

What is the function of veins?

• Carry high pressure blood away from the heart

• Carry low pressure blood to the heart

• Carry oxygenated blood to the tissues

• Carry blood away from the lungs

What is the role of capillaries in the circulatory system?

• Carry blood away from the heart

• Carry blood to the heart

• Connect arteries and veins and facilitate gas exchange

• Store oxygen in the blood

What is oxygen debt (EPOC)?

• The amount of oxygen needed to remove lactic acid after anaerobic respiration

• The amount of oxygen needed to start aerobic respiration

• The amount of carbon dioxide produced during respiration

• The amount of energy produced during respiration

What is the function of arteries?

• Carry blood away from the heart under high pressure

• Carry blood to the heart under low pressure

• Store oxygen in the blood

• Remove carbon dioxide from the blood

What is coronary heart disease (CHD)?

• A condition where the heart pumps too much blood

• A condition where the heart's blood supply is blocked by fatty substances

• A condition where the veins are blocked

• A condition where the arteries are too elastic

What is cardiac output?

• The amount of blood you can pump in one minute

• The amount of oxygen in the blood

• The amount of carbon dioxide in the blood

• The amount of energy produced by the heart

What is the process called that is carried out by cells in living things and supplies them with energy?

• Respiration

• Inhaling

• Exhaling

• Blood Plasma
