why glucose is converted to starch for storage, rather than being stored as it is?

Answer 1

Starch (Glycogen) is a polymer of glucose (polysaccharide). It is easier to store it in polymer form. It is also easier for the organisms to then control the usage of the starch through hormones and avoid waste. Insulin stimulates glycogenesis (formation of starch) and glucagon stimulated glycogenolysis (breakdown of starch)

Answer 2

This is a complex question- and 'Why' questions are particularly tough...

Glucose is as basic as it gets for a sugar. Small and dissolves in water. Not ideal for storage. Starch is a big ol' molecule that is not water soluble... and can be built out of glucose. Better for storing in wet environments, like the insides of animals.

The word 'converted' is also a difficult definition to follow closely. Think of all of the molecules like already built lego cars. They are torn apart (through various processes) into blocks, then rebuilt into other cars, or houses, or that really cool pirate ship. Direct conversion may or may not be precisely what is happening.

Through a complex process, glucose molecules _are_ included in the production of starches (so partial credit only to CommonSense), then, when needed, the starch is broken down into glucose for use by the cells.

Answer 3

Starch is converted to Glucose..
Not Glucose to Starch..
