Question

cellulose is made up of glucose units attached with __________ linkages.
select the correct answer below:
α-glucosidic
α-glycosidic
β-glucosidic
β-glycosidic

Explanation:

Step1: Analyze cellulose structure

Cellulose is a polysaccharide.

Step2: Recall glycosidic linkage type

It is composed of glucose units linked by $\beta$-glycosidic linkages. $\alpha$-glycosidic linkages are in glycogen and starch. $\beta$-glucosidic is incorrect term (glycosidic is the right general term for the linkage in context of sugar - sugar bonds in polysaccharides). $\alpha$-glycosidic is wrong as it's not for cellulose.

Answer:

$\beta$-glycosidic
