Which of the following carbohydrates is an important structural molecule, yet humans cannot digest it?
A
glucose
B
starch
C
cellulose (fiber)
D
triglyceride
Explanation: 

Detailed explanation-1: -Cellulose is the single most common biochemical compound in living things. It forms the cell walls of plants and certain algae. Like most other animals, humans cannot digest cellulose, but it makes up most of the crucial dietary fiber in the human diet.

Detailed explanation-2: -Humans cannot digest cellulose.

Detailed explanation-3: -The glycosidic linkages in cellulose can’t be broken by human digestive enzymes, so humans are not able to digest cellulose. (That’s not to say that cellulose isn’t found in our diets, it just passes through us as undigested, insoluble fiber.)

Detailed explanation-4: -Cellulose [(C6H10O5)n] is a natural organic compound that is the most abundant biopolymer on the planet. It is a polysaccharide or complex carbohydrate made up of hundreds to thousands of glucose molecules linked together to form a chain.

Detailed explanation-5: -Glucose, or blood sugar, is the main source of energy for your body’s cells, tissues, and organs. Glucose can be used immediately or stored in the liver and muscles for later use.
