Transport of D- and L- glucose proceeds at the same rate down an electrochemical gradietn by which ofhte following processes? a. simple diffusion.
b. facilitated diffusion.
c. primary active transport.
d. cotransport.
e. counter transport.

Explanation:

Active transport is the movement of molecules or substance from a region of lower concentration to a region of higher concentration across a cell membrane against the concentration gradient.

Active transport requires cellular energy and are of two types:

primary active transport that uses adenosine triphosphate (ATP), and secondary active transport that uses an electrochemical gradient.

Active transport helps in the uptake of glucose in the intestines.

Cotransport or secondary active transport is the movement of molecules across a membrane it uses electrochemical potential difference that is created by pumping ions in or out of the cell.

Cotransport helps in the transport of glucose across the cell membrane.

im not in connections yet but i might can you some questions. what grade are you in?
