In tubular reabsorptiion, glucose and amino acids are reabsorbed by the process of (A) active transport (B) passive transport (C) osmosis (D) pinocytosis

In tubular reabsorption, glucose and amino acids are reabsorbed primarily through active transport. This process requires energy in the form of ATP, allowing the kidneys to reclaim valuable nutrients from the urine and return them to the bloodstream, ensuring that these essential molecules are not wasted. A common mistake in understanding this process is thinking it’s solely dependent on passive processes. While passive transport does play a role in other aspects of kidney function, the active transport of glucose and amino acids is vital to maintaining energy balance and overall health.
