When a pigment molecule in a light-harvesting complex absorbs a photon of light, While returning to its ground state, the electron transfers some of the energy from its excited state to an electron in a nearby pigment molecule.
- It takes a photon of light energy some distance before it reaches a pigment molecule like chlorophyll.
- An electron in the chlorophyll is "activated" by the photon. The energy imparted to the electron then moves from one pigment molecule to another until it reaches the reaction center, a pair of chlorophyll a molecules.
- An electron in the reaction center is then excited by this energy, causing it to break loose and travel to the primary electron acceptor.
- Therefore, it is said that the reaction center "donates" one electron to the main electron acceptor.

<em>A. 11.0 L is the researcher's volume measurement to the SL units of liter</em>
<u>Explanation:</u>
Given that a researcher recorded that the chemical reaction has water = 2.90 gallon.
We have to convert the researcher's volume into the SL units of liter.
<em>So, we know that 1 gallon = 3.875 liters</em>.
Then we have to convert 2.90 gallons of water in to liters.
Then , volume in L =
=
= 
<em>Then the required volume in
</em>
