Photosynthesis: Part 5: Light Independent Reactions

Question 1

What happens during Light Independent reactions?

Answer 1

Sugar is made.

Question 2

What happens during the Calvin Cycle?

Answer 2

CO2 combines with electrons and protons carried by NADP to produce sugar (PGAL).

Question 3

What is Carbon Fixation?

Answer 3

The corporation of Carbon Dioxide into sugar is called Carbon Fixation.

Question 4

What is a formula that can summarize the Calvin Cycle?

Answer 4

CO2 + (H+ (protons)) + electrons——–> PGAL

Question 5

Extra Information

Answer 5

• Large amounts of ATP are needed to keep the Calvin Cycle going.
• PGAL——-> Phosphoglyceraldehyde ———> 3 carbon sugar———–> C(H2O)n
• An important enzyme is need for the Calvin Cycle: Rubisco—-> Ribulose biphosphate
