Multiple Choice

How are glucose and amino acids transported back into the capillaries during tubular reabsorption in the kidneys?

By osmosis following the movement of water

Through passive diffusion across the tubular membrane

Through filtration driven by blood pressure

Via active transport using specific carrier proteins

Verified step by step guidance

Understand that tubular reabsorption in the kidneys involves the movement of substances from the renal tubules back into the blood in the capillaries.

Recognize that glucose and amino acids are reabsorbed from the filtrate in the renal tubules back into the bloodstream.

Identify that active transport is a process that requires energy, usually in the form of ATP, to move substances against their concentration gradient.

Learn that specific carrier proteins in the tubular cell membranes facilitate the active transport of glucose and amino acids.

Acknowledge that these carrier proteins bind to glucose and amino acids, allowing them to be transported across the tubular membrane and into the capillaries.
