Homework Answers
3). Both glucose and amino acid are taken up by the cell through the facilitated diffusion, which needs a transport molecule. Facilitated diffusion involves the transport of transport of molecules using the membrane-bound proteins. For example, ion channels allow the transport of ions into and out of the cell, which are otherwise, cannot pass through cell membrane. Glucose binds to the carrier molecule present on the cell membrane, and enter into the cell; this process is facilitated by insulin. The binding of glucose to tits carrier molecule is specific similarly, the binding of amino acid to tits carrier molecule is also specific.
