Which statement accurately describes the absorption of nutrients via facilitated transport? a. It takes place in the large intestine. b. It requires a specific carrier. c. This process is also known as endocytosis. d. This process requires a concentration gradient.

Facilitated transport is a fascinating process where specific carrier proteins help move nutrients across cell membranes without needing energy. This mechanism ensures that essential nutrients, like glucose and amino acids, can efficiently enter cells even against concentration gradients, but only at times when such gradients exist. Unlike some transportation processes, facilitated transport doesn’t involve the engulfing of materials like endocytosis does, making it a more streamlined and efficient means of nutrient absorption. It’s particularly vital in cells lining the intestines, ensuring nutrients are picked up promptly and efficiently!
