Answer:
break them down to monosaccharides
Explanation:
The covalent bonds between Carbon and Hydrogen atoms in polysaccharides and their monomers contain high energy that is tapped by cells to make ATPs (the energy currency of cell) in cellular respiration. Carbohydrates, such as amylose, glycogen, and starch, therefore, need to be broken down to smaller units like glucose that can be utilized by cells metabolic pathways. Carbohydrates are easily hydrolysed to provide energy when the body requires it.
