Which one of the following would be correctly classified as a protein? answer cellulose enzymes starch cholesterol

The answer to this question is Enzymes.

An enzyme is defined as a protein catalyst. Many enzymes consist of a protein, the apoenzyme,  and a non protein component known as a cofactor required for catalytic activity. The complete enzyme consisting of  the apoenzyme and its cofactor is called the holoenzyme. 

Cellulose is a polysaccharide made up of glucose units.

Starch is polysaccharide composed of amylose and amylopectin.

there are 35 white marbles

step-by-step explanation:

y- yellow marbles

4y + 5 = 45

subtract 5 from both sides

y = 10

plug in 10 to get 40 yellow marbles then subtract by 5 to get 35 marbles

thus there are only 10 yellow marbles
