What is the difference between the processes of nutrient absorption by simple diffusion versus active transport?
A) ?Nutrients absorbed by active transport cross freely into intestinal cells, while nutrients absorbed by simple diffusion move against their concentration gradient, which requires energy. B) ?Nutrients absorbed by simple diffusion cross freely into intestinal cells, while nutrients absorbed by active transport move against their concentration gradient, which requires energy. C) ?Nutrients absorbed by simple diffusion need a specific carrier molecule to transport them into intestinal cells, while nutrients absorbed by active transport move against their concentration gradient, which does not require energy. D) ?Nutrients absorbed by simple diffusion cross freely into intestinal cells, while nutrients absorbed by active transport need a specific carrier molecule to transport them into intestinal cells, which does not require energy.
