Definitions

Question 1

TP (triose phosphate)

Answer 1

3-carbon compound formed when a molecule of GP is reduced in the Calvin cycle of the light independent reaction

Question 2

NADP

Answer 2

A coenzyme involved in transferring H from water (released in photolysis) to the light independent reaction

Question 3

Chlorophyll

Answer 3

A photosynthetic pigment found in chloroplasts. There are two types a and b.

Question 4

Chloroplast

Answer 4

A protein and photosynthetic pigment complex found in the thylakoid membrane of chloroplasts

Question 5

PS11

Answer 5

A site where electrons are excited during the light dependent reaction of photosynthesis

Question 6

Limiting factor

Answer 6

A variable that prevents a reaction, such as photosynthesis, from going any faster. If the factor is increased the process will go at a faster rate until another factor becomes limiting.

Question 7

Chloroplast

Answer 7

An organelle found in plant cells where photosynthesis occurs

Question 8

Stroma

Answer 8

Fluid filled matrix of chloroplasts. Site of light independent reactions.

Question 9

Robi lose biphosphate (RuBP)

Answer 9

5 carbon compound that is an acceptor molecule for carbon dioxide

Question 10

Light independent stage

Answer 10

Second stage of photosynthesis. ATP and reduced NADP (from the light dependent reaction) are used to make carbohydrates from carbon dioxide

Question 11

Light dependent stage

Answer 11

The first stage of photosynthesis. Light energy is absorbed by photosynthetic pigments and ATP and reduced NADP are produced

Question 12

Pigment

Answer 12

A chemical that absorbs specific wavelengths (colours) of light and reflects others
