AQA Biology Paper 1- Bioenergetics

Where does the energy for photosynthesis come from?

• Sunlight

• The ground

• Sugars the plant makes

• Carbon dioxide in the air

What gas is produced during photosynthesis?

• Oxygen

• Carbon dioxide

• Glucose

• Nitrogen

What is the best definition of photosynthesis?

• Using light to make proteins

• Using light energy to make starch

• Using light energy to make glucose

• Using light energy to make food.

What is anaerobic respiration?

• Respiration without any/much oxygen

• Respiration with oxygen

• Respiration using carbon dioxide

What is aerobic respiration?

• Respiration with oxygen

• Respiration without oxygen

• Respiration with carbon dioxide

• Respiration without carbon dioxide

Which type of respiration produces the most energy?

• Aerobic

• Anaerobic

• They both produce the same

• Photosynthesis

During exercise, which bodily process increase?

• The heart rate & the breathing rate

• The rate of digestion, the heart rate & the breathing rate

• The heart rate only

What is oxygen debt?

• The extra oxygen required after exercise to react with the lactic acid.

• The extra oxygen required before exercise to react with the lactic acid.

• The extra oxygen required during exercise to react with the glucose.

• The extra oxygen required after exercise to react with the glucose.

What is the best definition of metabolism?

• A The rate at which chemical reactions occur in cells and the body
• B The rate at which digestion occurs
• C The speed at which toxins are broken down by the body
• D The speed at which enzymes work in the digestive system

What type of reaction is photosynthesis?

• Bioluminescence

• Endothermic

• Decomposition

• Exothermic
