Which absorptive process in the small intestine requires a carrier and energy to transport nutrients into absorptive cells?

Question

Quizplus · Accepted Answer

Active absorption requires a carrier and energy to transport nutrients across the cell membrane and into the absorptive cells of the small intestine. This process is necessary for the absorption of certain nutrients such as glucose, amino acids, and some vitamins. Phagocytosis is a process by which cells engulf and digest large particles such as bacteria or other cells, but it is not involved in nutrient absorption. Facilitated diffusion is a passive process that requires a carrier protein to move nutrients across the cell membrane, but it does not require energy. Passive diffusion is a passive process that does not require a carrier protein or energy, but it is limited in its ability to transport certain nutrients.
