Glycogen is a multibranched polysaccharide of glucose that serves as a form of energy storage in animals, fungi, and bacteria.Glycogen functions as one of two forms of energy reserves, glycogen being for short-term and the other form being triglyceride stores in adipose tissue (i.e., body fat) for long-term storage.

Glycogen is the energy storage in animals, starch is the energy storage in plants, and cellulose makes up the cell wall in plants (chitin makes up cell wall in fungi and exoskeleton of arthropods).

Compare and contrast between glycogen and cellulose? (

Glycogen and cellulose are polysaccharides formed from glucose fragments. Glycogen accumulates in the cells of fungi and animals as a spare fast source of energy. Cellulose is found in the...

Starch, glycogen, and cellulose are all composed of the same monosaccharide - Glucose. How are all their structures different that allow them to have very different functions

Starch is a polysaccharide comprising glucose monomers joined in α 1,4 linkages.It consists of two types of molecules: the linear and helical amylose and the branched amylopectin. Amyloseis almost unbranched and helical, but could contain...

A starch molecule consists of countless monosaccharide simple sugars that have bonded together by dehydration synthesis. What might happen if you added water to a starch molecule?

When starch is heated with water, the starch granules swell and burst, causing them to break down and release the glucose molecules into the water. Consequently, the starch molecules interact with more water, increasing the randomness of the solution in...

In experiment using cellulose bag of starch solution placed in iodine solution, what is occurring? Diffusion, osmosis, or both? Please explain answer, thank you!

Iodine solution passes through the cellulose bag due to diffusion. For osmosis, it is necessary to overcome a semipermeable membrane. Сellulose is not such a membrane.

Enzymes catalyze the degradation of biomolecules, like starch and cellulose into the simple sugar glucose. Why is it that humans can digest starch but not cellulose?

There are no corresponding enzymes.

What are the structural and functional differences between starch and cellulose

Starch is formed from alpha glucose, while cellulose is made of beta glucose. The difference in the linkages lends to differences in 3-D structure and function. Starch can be straight or branched and is used as energy storage for plants...

Why do cells need to store glucose in the form of glycogen and what is the structural advantage of glycogen for animals as compared to either amylose or amylopectin?

Glycogen is more highly branched than amylopectin and amylose. The advantage of glycogen’s highly branched structure is that the multiple ends are where enzymes start to cleave off glucose molecules....

Complex carbohydrates, like starch and cellulose, are natural polymers where simple sugar molecules are the monomers. Both starch and cellulose consist of long chains of what simple sugar molecule?

Polysaccharides A long chain of monosaccharides linked by glycosidic bonds is known as a polysaccharide. The chain may be branched or unbranched, and it may contain different types of monosaccharides....
