Introduction to Photosynthesis

Question 1

What is the equation for photosynthesis?

Answer 1

6CO2 + 6H2O → C6H12O6 + 6O2

Question 2

What are the two types of reactions in photosynthesis?

Answer 2

light dependent reaction - LDR

light independent reaction - LIR

Question 3

What is light dependent reaction - LDR?

Answer 3

• uses light energy to make ATP and reduced NADP (NADPH)
• takes place on the membrane of the thylakoid - large surface area
• sometimes called photophosphorylation

Question 4

What is a light independent reaction/

Answer 4

• uses products of LDR - ATP + NADPH - to make useful organic compounds
• takes place in the stroma
• also known as the calvin cycle
