Flashcards in Lecture 12 Deck (18):
1

What the light dependent reactions provide?

They provide the energy used to create sugars

2

What is carbon fixation?

The conversion of inorganic carbons into organic carbons

3

Where does the Calvin cycle take place?

In the stroma

4

What steps does the Calvin cycle involve?

1. Carbon fixation
2. Reduction
3. Regeneration of ribulose 1,5- biphosphate

5

How many turns does it takes to yield 1 glucose in the Calvin cycle?

6

6

When g3p is formed what happens to it?

It is transported out of the chloroplast where reverse reactions of glycolysis produce fructose-6 phosphates and glucose- 6 phosphates

7

What does rubisco do?

it catalyzes carbon fixation

8

What is photorespiration?

the process which incorporates oxygen to RuBP, it is also catalyzed by rubisco.

9

Why do plants photorespire?

To protect themselves from photo oxidative damage

10

What are c3 plants?

The type of plant that does not possess any mechanism to regulate photorespiration

11

What is c4 plants?

Plants where the CO2 fixation to PEP and the calvin cycle occur in 2 different cells

12

What are CAM plants?

The PEP pathway and the calvin cycle occur within the same cell but at different time during the day

13

Where does co2 fixation occur in c4 plants?

mesophyll cell

14

Where do the calvin cycle occur in c4 plants?

bundle sheath cell

15

What are examples of c4 plants?

corn, sugar cane and grass

16

What are examples of CAM plants?

cacti and pineapples

17

When does the calvin cycle happen in CAM plants?

during the day

18

Where reactions occur in the CAM plant?

mesophyll cell
