AQA Biology Paper 1 (Bioenergetics)

Where does the energy for photosynthesis come from?

• A Sunlight
• B The ground
• C Sugars the plant makes
• D Carbon dioxide in the air

What gas is produced during photosynthesis?

• A Oxygen
• B Carbon dioxide
• C Glucose
• D Nitrogen

What is the equation for photosynthesis?

• A Carbon dioxide + Water = Glucose + oxygen

• B Carbon dioxide + water = glucose + oxygen

• C Oxygen + glucose = water + carbon dioxide

• D Glucose + water = Carbon dioxide + oxygen

What is the best definition of photosynthesis?

• A Using light to make proteins
• B Using light energy to make starch
• C Using light energy to make glucose
• D Using light energy to make food.

What has happened to the concentration of oxygen in the Earth’s atmosphere?

• A Increased
• B Decreased
• C Remained the same
• D There isn’t any

The rate of photosynthesis can be determined by:

• A measuring the volume of oxygen produced in 2 minutes
• B measuring the volume of oxygen produced
• C measuring the volume of oxygen used in 2 minutes
• D measuring the volume of oxygen used.

What are amino acids used for?

• A To make proteins
• B For an energy storage molecule
• C To make fats
• D To strengthen cell walls

What is aerobic respiration?

• A Respiration with oxygen
• B Respiration without oxygen
• C Respiration with carbon dioxide
• D Respiration without carbon dioxide

What is anaerobic respiration?

• A Respiration without any/much oxygen
• B Respiration with oxygen
• C Respiration using carbon dioxide

Which type of respiration produces the most energy?

• A Aerobic
• B Anaerobic
• C They both produce the same
• D Photosynthesis
