The photosystem channels the excitation energy gathered by absorption of light by any one of the pigment molecules to a specific "reaction center chlorophyll," which in turn passes the energy to
-photosystem I.
-photosystem II.
-the primary electron acceptor.
-the secondary electron center.
-cytochrome.
Answer: -the primary electron acceptor.
Explanation:
The photosystem II has a reaction center, in the reaction center the energy from sunlight is converted into high energy electrons. At the center of the reaction center, chlorophyll molecule is present which absorbs the light and one of its electron is promoted to the higher energy.
The high energy electron is hop downward and it is transferred to the plastoquinone A, which is a primary electron acceptor. Then the electron is transferred to the plastoquinone B. The plastoquinone B will receives enough electrons it delivers its electron to the electron transfer chain.
Answer:
a= 17.69 m/s^2
Explanation:
Step one:
given data
A car accelerates uniformly from rest to 23 m/s
u= 0m/s
v= 23m/s
distance= 30m
Step two:
We know that
acceleration= velocity/time
also,
velocity= distance/time
23= 30/t
t= 30/23
t= 1.30 seconds
hence
acceleration= 23/1.30
accelaration= 17.69 m/s^2
Answer: Car brakes produces more energy then the bicycle because the cars wheels produces a much bigger force that makes the car go and to stop that force the car uses greater amount of energy that transfers to heat but in a bicycle the wheels do not turn that fast so when you press the break there is less energy that transfer to heat.
