Question

The GLUT transporter moves glucose through a transport protein in the same direction as its concentration gradient. The action of the glucose transporter is an example of _____________. The SGLT transporter uses the sodium concentration gradient created by the sodium potassium ATPase to move glucose against its concentration gradient. The action of the SGLT transporter is an example of _______________.

Answer 1

Answer:

The correct answer is - facilitated transport and secondary active transport.

Explanation:

GLUT transporter is a glucose transporter that helps in moving the glucose to its concentration gradient through the cell membrane. It is a transport protein that uses passive transport of facilitated transport that moves down their concentration gradient and therefore does not require chemical energy from ATP hydrolysis in the transport step.

Sodium-based GLUT or SGLT is also a glucose transport protein that exhibits secondary active transport as it develops electrochemical potential difference by moving ions out of the cell membrane, this gradient allows the movement of ions and molecules.
