In which of these forms is carbohydrate stored in yam?

Answer Details

Carbohydrates in yam are primarily stored in the form of starch. Starch is a complex carbohydrate that is made up of long chains of glucose molecules. When yams photosynthesize, they convert the energy from sunlight into glucose, which they then store as starch in their underground tubers. Starch is an excellent storage molecule because it can be broken down into glucose when energy is needed. This allows yams to survive periods of low sunlight and water by using their stored starch for energy. The other carbohydrate options listed - glucose, maltose, glycogen, and cellulose - are not typically stored in yams. Glucose is a simple sugar that is used for energy production in cells. Maltose is a disaccharide made up of two glucose molecules and is found in grains and some vegetables, but not typically in yams. Glycogen is a complex carbohydrate that is similar to starch, but it is primarily stored in animals rather than plants. Finally, cellulose is a structural carbohydrate found in plant cell walls, and it is not typically used for energy storage.
