C) active transport
D) bulk flow

Question

Quizplus · Accepted Answer

Most nutrients are absorbed through active transport, which requires energy and carrier proteins to move molecules from an area of low concentration to an area of high concentration. This mechanism allows the body to selectively absorb nutrients, such as glucose and amino acids, from the intestinal lumen to the bloodstream. Simple diffusion and facilitated diffusion may also play a role in nutrient absorption for certain molecules, but they are not the main mechanisms. Bulk flow is a mechanism for moving fluids and particles through large vessels, such as blood vessels or lymphatic vessels, but it is not directly involved in nutrient absorption by the intestinal mucosa.
