What part of the body uses active transport to take up nutrients after concentration has reached equilibrium
jekas [21]

The villi of the small intestine use active transport to take up nutrients after concentration has reached equilibrium.

<h3>What is Active transport?</h3>

Active transport may be defined as the process that occurs against the concentration gradient and is mediated by carrier proteins. Metabolic energy is used to move ions or molecules against a concentration gradient.

During the process of digestion, the villi in the small intestine enthrall the soluble nutrients gradually. Over time, the concentration of nutrients in the villi acquires an equilibrium with the concentration in the gut. Until here, the nutrient uptake is carried by the process of passive diffusion.

But after attaining the equilibrium, the nutrient uptake is carried by the process of active transport.

The complete question is as follows:

What part of the body uses active transport to take up nutrients after concentration has reached equilibrium?

  • Lungs
  • Stomach
  • Small intestine
  • Liver

Therefore, the correct option for this question is C, i.e. small intestine.
