Year 10 Biology Quiz 3 - Photosynthesis and respiration

Which of these is the word equation for aerobic respiration?

• Carbon dioxide + water --> glucose + oxygen

• Glucose + oxygen --> carbon dioxide + water

In a cell, aerobic respiration takes place inside the ___________

Respiration transfers energy to it's surroundings.

This means respiration is an __________ reaction

Respiration is the process of ____________ energy from the breakdown of glucose, to energy that cells can use

• Creating

• Producing

• Making

• Transferring

Match the following:

• Aerobic respiration

• The products of anaerobic respiration (in plants and yeast)

• Anaerobic respiration

• The products of aerobic respiration

• Lactic acid

• The products of anaerobic respiration (in animals)

• Ethanol and carbon dioxide

• The type of respiration which happens when there is an absence of oxygen

• Carbon dioxide + water

• The type of respiration which happens when plenty of oxygen is available

One problem with anaerobic respiration is that it produces less ​ ​ (a)   compared to anaerobic respiration.

Another problem is the ​ (b)   produced causes muscle cramp and ​ (c)   .

• ATP
• lactic acid
• fatigue
• DNA
• carbon dioxide
• glucose
• oxygen

After anaerobic respiration, people will need to breathe heavily.

This is to repay the oxygen ____ they have built up.

What is the word equation for photosynthesis?

• Carbon dioxide + water --> oxygen + glucose

• Oxygen + glucose --> carbon dioxide + water

Photosynthesis happens inside the leaves, in ​ (a)   .

These contain a chemical called ​ (b)   which traps the light.

Photosynthesis is an ​ (c)   reaction which means it takes in energy from the environment.

• chloroplasts
• chlorophyll
• endothermic
• exothermic
• mitochondria
• glucose
• oxyge
• oxygen

Photosynthesis stops working if a plant gets too hot because the enzymes become ...
