Question

1. Kermit the frog is green because:

Select one:

he absorbs all wavelengths of light

he reflects short wavelengths of visible light

he absorbs mid wavelengths of visible light

he reflects long wavelengths of visible light

he reflects mid wavelengths of visible light

2.

In photosynthesis chemiosmosis occurs due to:

Select one:

H⁺ flowing down a concentration gradient, resulting in NADPH production

P680+ being reduced to P680

_{H⁺ flowing down a concentration gradient, resulting in ATP production}

electrons flowing down a concentration gradient, resulting in NADPH production

oxidizing water, resulting in NADPH production

3.

This occurs in Photosystem II but not Photosystem I in the light-dependent reactions.

Select one:

absorption of light

use of light energy

elevation of electrons to higher energy levels

passing of electrons to electron carriers

oxidation of H₂0

Answer 1

1. E. he reflects mid wavelengths of visible light

Kermit frog absorb sunlight and reflect blue light from iridophores which passes through xanthophyll (yellow) and filter through top cells to produce green color(mid range)

2. C. H+ flowing down a concentration gradient, resulting in ATP production

H+ is high in lumen of thylakoid which passes to stroma through ATP synthase and this proton motive force triggers the rotatory motion of ATP synthase to produce ATP.

3. E. Oxidation of H20

Photolysis (oxidation) of water only take place in PSII to produce electron.
