Phototropin has two LOV domains and a kinase domain, separated by an α-helical region (Jα). In the absence of light, which one of the following is correct prediction?

#Unit 6. System Physiology – Plant
  1. the N-terminal region, including the LOV domains, “cages” and represses the activity of the kinase domain
  2. the C-terminal region, including the LOV domains, “cages” and represses the activity of the kinase domain
  3. the N-terminal region, including the LOV domains, “uncages” and re-expresses the activity of the kinase domain
  4. the C-terminal region, including the LOV domains, “uncages” and re-expresses the activity of the kinase domain

Oxygen-Evolving Organisms Have two Photosystems that Operate in Series, explain by emerson that is the Photosystem I preferentially absorbs far-red light of wavelengths greater than 680 nm; photosystem II preferentially absorbs red light of 680 nm and is driven very poorly by far-red light; Another difference between the photosystems is that,

a.) Photosystem I produces a strong reductant, capable of reducing NADP+, and a weak oxidant

b.) Photosystem I produces a very strong oxidant, capable of oxidizing water, and a weaker reductant than the one produced by photosystem II

c.) Photosystem II produces a strong reductant, capable of reducing NADP+, and a weak oxidant

d.) Photosystem II produces a very strong oxidant, capable of oxidizing water, and a weaker reductant than the one produced by photosystem I
