Cells lining the small intestine absorb glucose. which of the following is required to transport glucose molecules across the cell membranes of the intestine? . a: atp to bind the glucose molecules . b: atp to start the process . c: adp to break down the glucose molecules

Transporting molecules through a membrane against their concentration gradient is called active transport. It needs a transporter (protein) and energy (ATP). ATP doesn't bind to the glucose molecules, the transporter does. Also the glucose isn't broken down So the only correct answer is B :)

The correct answer is B. ATP to start the process. ATP or Adenosine triphosphate is energy that is needed by the cells in its processes.

ADP doesn't break down glucose molecules but is a product after energy (ATP) is consumed. ATP is energy needed and doesn't bind to the glucose molecules but instead the transporter protein does.
