Photosynthesis

Question 1

What does the LDR need

Answer 1

• Light-for energy
• NADP-is a coenzyme,H carrier,H comes from photolysis
• H20-broken down using the energy from light

Question 2

What are the end products for the LDR

Answer 2

• ATP-from ADP+P
• NADPH2-carries H to Dark reaction
• O2- released into atmosphere

Question 3

What happens to chlorophyll in the LDR

Answer 3

Absorbs energy and E becomes excited (goes to higher energy level)

Question 4

What happens when E drop back

Answer 4

High energy is given off and can be used for photolysis (2H20-> 2H2+O2(^) split water

Question 5

Calvin cycle

Answer 5

• What it starts with it also ends with ,
• light independent reaction
• occurs in stroma of chloroplasts

Question 6

Dark reaction

Answer 6

Occurs in stroma
•is dense solution outside the grana
•enzymes found in liquidly solution

Question 7

What does the dark reaction need

Answer 7

• ATP & NADPH2-from light reaction

* Co2-from atmosphere

Question 8

End product of dark reaction

Answer 8

Carbohydrates-glucose

Question 9

How can the dark reaction proceed

Answer 9

With or without light

Question 10

What 3-c compound do CO2 and H combine to produce

Answer 10

PGAL-phosphoglyceraldehyde

Question 11

PGALS

Answer 11

2 PGALS join to form 1 glucose (6 carbon compound)

Question 12

What can glucose be used for

Answer 12

As energy source in cellular respiration

Question 13

What can glucose be synthesized into to

Answer 13

Into other metabolic compounds

Such as sucrose,lipids,proteins,nucleic acids

Question 14

What can glucose be converted into

Answer 14

Storage products or structural components by dehydration synthesis

Such as starch,cellulose

Question 15

What can glucose be used for

Answer 15

The end product in a cell or transported to other tissues

Question 16

What is photosynthesis

Answer 16

The process of capturing energy of sunlight and transforming it into chemical energy

Question 17

What are the reactants of photosynthesis

Answer 17

CO2, H2O

Question 18

What are the products of photosynthesis

Answer 18

Glucose, and oxygen

Question 19

What is required for photosynthesis to happen

Answer 19

Pigments and enzymes in chloroplasts

Question 20

What are photosynthetic pigments in plants capable of

Answer 20

Absorbing visible light of different wavelengths

Question 21

What happens to light that photosynthetic pigments do not absorb

Answer 21

It either passes through or is reflected

Question 22

What are photosynthetic pigments

Answer 22

Organic molecules which have a metal ion (magnesium) at the center

Question 23

Which rays are at the end of the electromagnetic spectrum and have the shortest wavelengths and High frequencies

Answer 23

Gamma rays

Question 24

Which rays are at the other end of the electromagnetic spectrum and have the longest wavelengths and low frequencies

Answer 24

Radio waves

Question 25

Which Ray is near the center of the spectrum and has intermediate wavelengths and frequencies

Answer 25

Visible light

Question 26

Where does the light dependent phase of photosynthesis occur

Answer 26

Thylakoid

Question 27

Where does the light dependent phase of photosynthesis occur

Answer 27

Stroma

Question 28

How are the light independent and light dependent phases linked

Answer 28

Light reaction makes NADPH and ATP energy and the dark reaction uses the energies

Question 29

Where does the light dependent reaction occur

Answer 29

Within the grana; enzymes embedded in membrane
