Photosynthesis

Question 1

What did the overall reaction of photosynthesis?

Answer 1

Carbon dioxide + water -> sugar + oxygen

Question 2

What is the definition of photosynthesis?

Answer 2

Light energy is converted into chemical energy through a series of enzyme-controlled reactions

Question 3

What are the names of the stages in photosynthesis?

Answer 3

Light reactions + Carbon fixation

Question 4

What is produced in the first stage that goes onto the second stage and what leaves the cell?

Answer 4

Hydrogen and ATP go to the second stage
Oxygen diffuses from the cell

Question 5

Where does the energy come from to perform the second stage (carbon fixation)

Answer 5

ATP -> ADP + Pi

Question 6

What is produced during Carbon fixation?

Answer 6

Glucose

Question 7

What is the reaction for Carbon fixation?

Answer 7

Carbon dioxide + hydrogen -> glucose

Question 8

What is the reaction for light reactions?

Answer 8

Light
Water ——> oxygen + hydrogen
ADP + Pi > ATP

Question 9

What is the sugar produced from photosynthesis used for

Answer 9

Respiration
Converted into starch (storage)
Converted into cellulose(found in cell walls)

Question 10

What is a limiting factor

Answer 10

Any factor that can prevent a reaction progressing at its fastest rate

Question 11

What are three limiting factors of photosynthesis

Answer 11

Light intensity
Carbon dioxide concentration
Temperature

Question 12

If a limiting factor of photosynthesis increases but reaction rate does not increase what is happening

Answer 12

The other limiting factors are slowing down reaction rate
