Unit 2: Photosynthesis & Cellular Respiration

What is the purpose of photosynthesis?

• To convert chemical energy in food to chemical energy stored in the form of ATP

• To make food for plants

• To make ATP for plants

• To make light energy

What are the reactants of photosynthesis?

• Carbon dioxide, oxygen, light

• Oxygen, water, light

• Oxygen, glucose, light

• Carbon dioxide, water, light

What are the products of photosynthesis?

• Carbon dioxide, glucose

• Oxygen, glucose

• Water, oxygen, light

• Carbon dioxide, water

What is the general equation for photosynthesis?

• C6H12O6 + 6O2 → ATP + 6H2O + 6CO2

• 6H2O + 6CO2 + Light → C6H12O6 + 6O2

• 6H2O + 6CO2 → ATP + C6H12O6 + 6O2

• C6H12O6 + 6O2 + Light → 6H2O + 6CO2
