Gel filtration and SDS-PAGE could be used for <u>determining a molecular weight of proteins</u>, such as tyrosinase. In both methods, molecules are separated based on their size. <u>Gel filtration</u> measures the molecular weight of <u>native proteins</u> and <u>SDS-PAGE</u> measures the molecular weight of <u>denaturated proteins</u>.
Do you mean electron? If so they are molecules that transport electrons during cellular respiration.
The answer is B: proteins and lipids.
Also carbohydrates
I have kinda of the same question but I don’t know it
