GCSE Biology Respiration Revision Quiz

State the limiting factors for photosynthesis.

• Temperature, light intensity, Time of day
• Temperature, carbon dioxide concentration, light intensity
• Temperature, water concentration, light intensity
• Water availability, oxygen concentration, light intensity

Which is the correct description of aerobic respiration?

• A physical reaction that takes place in the presence of oxygen in cells to release energy.
• A chemical reaction that takes place in the absence of oxygen in cells to release energy.
• A chemical reaction that takes place in the presence of oxygen in cells to release energy.
• A chemical reaction that takes place in the presence of oxygen in cells using energy.

Which statements about aerobic respiration are true? (choose all true statements).

• Respiration occurs in the nucleus of cells.
• Energy released is used to maintain a constant temperature in animals.
• Respiration is limited if temperature gets too high.
• Respiration is an exothermic reaction.
• Plants don’t respire.

What is the word equation for RESPIRATION?

• glucose + oxygen + energy >>>> carbon dioxide + water
• carbon dioxide + oxygen >>>> glucose + water + energy
• carbon dioxide + water + energy >>>> glucose + oxygen
• glucose + oxygen >>>> carbon dioxide + water + energy
• glucogen + oxygen >>>> carbon dioxide + water + energy

Aerobic respiration. (Select all the statement true).

• Mitochondria contain enzymes which catalase reactions.
• A waste product of aerobic respiration is glucose.
• Respiration is an endothermic reaction because if transfers energy from the surroundings.
• Respiration is an exothermic reaction because if transfers energy to the surroundings.
• The site of cellular respiration is the ribosome.

The site of respiration is the mitochondria.

• true
• false

A waste product of aerobic respiration is carbon monoxide.

• true
• false

Give one adaptation of a muscle cell, for respiration.

• Long and thin.
• Many ribosomes to process proteins.
• Many muscle cells to provide strength.
• Large and powerful.
• Many mitochondria to provide/release energy.

What adaptations do the mitochondria have?

• Has flagellum to move around the cell.
• Small inner surface area, contains no enzymes.
• Very small to pass through cell membrane.
• Large inner surface area, contain enzymes.
• Lots of DNA to make energy with.

Is aerobic respiration endothermic or exothermic?

• Endothermic – releases energy
• Endothermic – absorbs energy
• Exothermic – releases energy
• Exothermic – absorbs energy
