All of the following statements concerning the light-capturing reactions of photosynthesis are true except
(A) An initial event is the excitation of electrons in chlorophyll by light energy.
(B) The excited electrons are raised to a higher energy level.
(C) If not captured, the excited electrons drop back to their initial energy levels.
(D) If captured, some of the energy of the excited electrons is used to split carbon dioxide into carbon and oxygen.
(E) Light is absorbed by pigments that are embedded in membranes.

The right answer is (D)

Explanation:

If captured, some of the energy of the excited electrons is used to split carbon dioxide into carbon and oxygen.

Electron when in excited state either it jumps to the higher orbital if it has absorbed energy or it can fall to a lower orbital.

first let us lay out the formula for potential

and kinetic energy:

pe = mgh

ke = (mv^2)/2

where: m=mass, v=velocity, g=gravitational

acceleration, h=height

calculating for mass using the known values of

pe:

340j = m (9.81 m/s^2) (50ft) (1m/3.28ft)

m = 2.27 kg

the law of conservation of energy states that

energy is neither created nor destroyed. therefore, the change in kinetic

energy from 50 ft to 35 ft would be equal to the change in potential energy

from 50 ft to 35 ft. however it would be opposite in signs since one is losing

while other is gaining.

ke(35ft) – ke(50ft) = - [ pe(35ft) – pe(50ft]

ke(50ft) = 0 since the brick is initially at rest

ke(35ft) = 340j - 2.27kg (9.81 m/s^2) (35ft)

(1m/3.28 ft)

ke(35ft)

= 102.38 j
