Answer: Option A.

Explanation:

Villi are the finger like projection present in the surface of small intestine in circular folds.

Villi is the organelle that functions to increase the surface area ( internal surface) of small intestine walls and provide more surface area for absorption. The increased surface area increases absorption of useful nutrients such as amino acid and monosaccherides and that passes into the semipermeable villi with the process of diffusion. Villi decreases the average distance travelled by nutrient molecules due to increased surface area and hence diffusion increases.

Hence, the correct option is A.

Mnenie [13.5K]

Answer:

Option A and C and D

Explanation:

Gylcogen is synthesized through a series of reactions through the assistance of enzymes. When glucose enter into the cell, it is converted into glucose 6-phosphate and then into glucose 1-phosphate and finally into uridine 5ʹ-diphosphate-glucose. In glycogenesis, glycogen is broken down into glucose 1-phosphate with the help of two glycogen phosphorylase. In the next stage the glycogen debranching enzyme untangles the branch points.

Hence, option A and C and D are correct

The almost pure cellulose obtained from the seed threads of Gossypium (cotton) is tough, fibrous, and completely insoluble in wa

olga55 [171]

Answer:

Cellulose is held by beta 1,4-glycosidic bonds making it linear while Glycogen is held by an alpha 1,4-glycosidic bond making it highly branched.

Explanation:

Cellulose and Glycogen are both carbohydrate polysaccharides formed from glucose monomers. According to the question, cellulose is a tough, fibrous, and insoluble (in water) polymer found to play a structural role in plants' cell wall while Glycogen is another polymer obtained from muscle or liver and disperses readily in hot water to make a turbid solution.

Although these two polysaccharides (cellulose and glycogen) are linked by (1, 4)-glycosidic bonds but the glucose monomers in CELLULOSE are linked by a beta 1,4-glycosidic, hence, making it a straight or linear polymer

GLYCOGEN, on the other hand, is linked by an alpha 1,4-glycosidic bond making it an highly branched polymer. This structure is responsible for the different physical properties of the two molecules.
