Which of the following is/are converted to simple carbohydrates during digestion?

Complex carbohydrates are formed from three or more sugar molecules but the sugar molecules are strung together to form longer, more complex chains. Complex carbohydrates include fibre and starch. Foods rich in complex carbohydrates include vegetables, whole grains, peas and beans. They are loaded with fibre, vitamins, minerals and micronutrients. During digestion, these complex carbohydrates are cleaved into single 6 carbon molecular units. Then they are absorbed and transported to the cells in the blood. These sugar molecules are either metabolized immediately to provide energy for the cell or stored in liver and muscle cells as glycogen to be used for future energy needs.
