Photosynthesis: Chlorophyll Extraction And Absorption Spectrum

Question 1

What is a photon?

Answer 1

A “packet” of light energy that can be assigned a wavelength

Question 2

What does photon energy absorbed by chlorophyll permit?

Answer 2

The removal of elections from water (producing oxygen and protons), and the shuttling of the electrons and protons that drive the generation of ATP and reduction of CO2

Question 3

What is that pattern of absorption by a substance called?

Answer 3

Absorption spectrum

Question 4

Does changing the concentration of the pigment substantially alter the position (wavelength) of the peaks?

Answer 4

No

Question 5

Does changing the concentration of the pigment substantially alter the height (absórbanle) of the peaks?

Answer 5

Yes

Question 6

What appears to be the relationship between the concentration of pigment and the height of the peaks?

Answer 6

The higher the concentration, the higher the peak; the lower the concentration, the lower the peak

Question 7

Of the two (position of height), which would be more useful in identifying a substance?

Answer 7

The position would be more useful in identifying the substance because of where the peak may lie

Question 8

What would be the consequences to photosynthesis be if the chlorophyll molecule were transparent to light?

Answer 8

It would be unable to perform photosynthesis

Question 9

What would the absorption spectrum of a colorless, transparent substance look like?

Answer 9

Very low

Question 10

What is the major property of chlorophyll A, chlorophyll B, and carotids were taken advantage of in order to separate them from one another?

Answer 10

Color
