FACTOID #53: If you thought Antarctica was inhospitable, think again - its land area is only ninety-eight percent ice. Reassuringly, the other 2% is categorised as "barren rock".
The smooth endoplasmic reticulum is responsible for some carbohydrate metabolism. In the liver, for example, the cell breaks down the polysacharide glycogen. Eventually, the glycogen will be turned into glucose, and released into the blood, but first it is broken into glucose phosphate, an ion that, if released would harm our blood cells. So to remedy this, an enzyme found in the membrane of the smooth endoplasmic reticulum can remove the phosphate, allowing pure glucose to be released.
Typically, fruits are high in carbohydrates, although a large range is possible—between 2 and 40 percent, depending on the type of fruit and its maturity.
Carbohydrates are absorbed as monosaccharides (simple sugars such as glucose, fructose, and galactose that cannot be further broken down by hydrolysis) or as disaccharides (carbohydrates such as...
Carbohydrates are ingested primarily in the form of larger molecules, such as starch (the chief storage form of carbohydrates in plants), from which the smaller sugars eventually are produced by the...
