Final answer:
Active transport is the type of carbohydrate absorption that requires energy, transporting glucose and galactose into cells against their concentration gradient.
Step-by-step explanation:
When talking about the absorption of carbohydrates, the type of absorption that requires energy is known as active transport. This process involves the transportation of glucose and galactose into the epithelial cells by common protein carriers via secondary active transport, which is co-transport with sodium ions. Unlike simple diffusion or facilitated diffusion, active transport requires the use of energy because it moves substances against their concentration gradient.
