Question

Glucose enters cell through specific transport proteins .which specific transport proteins they are? Name them also.

Answer 1

Secondary Active Transport

Secondary active transport is another method by which cells import glucose. In this method, a transmembrane protein known as a symporter imports two sodium ions for every glucose molecule it imports. The method doesn't use ATP, but instead relies on the higher concentration gradient of sodium outside the cell relative to the cell interior. The positively charged sodium ions provide electrochemical energy to import glucose with or against the glucose concentration gradient. Secondary active transport is used by cells in the small intestine, heart, brain, kidneys and certain other organs.
