1. The four primary organic macromolecules
Carbohydrates are used to store energy and as structural components of cells
Animal cells store energy in the complex carbohydrate gylgogen
Plant cells store energy in complex carbohydrates called starches
Complex carbohydrates can be broken down into individual sugar molecules, which store energy in their chemical bonds
Digestion of carbohydrates starts in the mouth with the enzyme amylase which breaks the bonds between individual sugar molecules
Carbohydrates that cannot be digested are called dietary fiber (roughage)
glucose

2. The four primary organic macromolecules
Carbohydrates (sugars, starches) are used to store energy and as structural components of cells
Glycosidic bonds link together sugar molecules
