The difference in an area with high concentration and an area with low concentration is called the concentration gradient.
<h3>
What is Concentration Gradient ?</h3>
A concentration gradient occurs when the concentration of particles is higher in one area than another.
In passive transport, particles will diffuse down a concentration gradient, from areas of higher concentration to areas of lower concentration, until they are evenly spaced.
This difference in an area with high concentration and an area with low concentration is called the concentration gradient.

The physical properties used by scientists to describe all matter, sight, smell, taste, color, texture, mass, weight, volume, and density.
Answer:
The reactant that is reduced is 
Explanation:
The complete equation is as below:
<em>Recall that oxidation involves the gain of electrons while reduction involves the loss of electrons.</em>
In the above reaction, loses electrons to coenzyme Q and becomes reduced to FAD, hence the oxidizing agent. Coenzyme Q gains electrons and becomes oxidized to 
, hence the reducing agent.
<u>In order words, </u><u> is reduced while coenzyme Q is oxidized.</u>
