The reaction-center chlorophyll of photosystem i is known as p700 because
a) there are 700 chlorophyll molecules in the center
b) this pigment isbest at absorbing light with a wavelength of 700 nm.
c) there are 700 photosystem i components to each chloroplast.
d) it absorbs 700 photons per minute

The correct answer will be option-B.

Explanation:

Photosystem of a plant is complex pigment-protein molecules which absorbs the light energy required for the formation of a glucose molecule.

Two types of Photosystem are present in the plants which are: P₆₈₀ and P₇₀₀. The 680 and 700 denote the wavelength of the light energy absorbed by the pigment of the chloroplast. The electrons get excited only at their absorbing wavelength.

Thus, Option-B is the correct answer.

1. (1.2kw)x(15/60hours) = .3kwh --> a

2. (5kw)x(90/60hours)x(8cents/kwh) = $0.60 --> d

3. microwave --> 1200 watts = (1.2kw)x(6/60hours) = .12kwh

coffee-maker --> 900 watts = (.9kw)x(10/60hours) = .15kwh

therefore, it requires more energy for the coffee-maker to do the same amount of work.

so the answer is a.

1. what is the relationship between the shape of an enzyme and the reactions they catalyze?

2. how does an enzyme inhibitor work?

separate your answers so i dont get confused : )
