Question

Is GLUT4 Active Transport?

Answer 1

In cellular biology, transport is the movement of molecules across a cell wall from a neighborhood of lower concentration to a neighborhood of upper concentration—against the concentration gradient. transport requires cellular energy to realize this movement.

Complete answer:
No, GLUT4 may be a passive transporter of glucose down the concentration gradient. It's a glucose transporter present within the adipose tissues, skeletal and cardiac muscles. It facilitates diffusion of glucose across the cell wall into muscle and fat cells.
Examples of transport include the transportation of sodium out of the cell and potassium into the cell by the sodium-potassium pump. transport often takes place within the internal lining of the tiny intestine.
There are two sorts of glucose transport. Facilitated diffusion doesn't require ATP as glucose is transported down the concentration gradient, e.g. GLUT. Glucose is additionally transported by secondary transport by SGLTs (sodium-glucose linked transporters). They do not utilise ATP on to transport glucose against the concentration gradient, instead, believe the sodium gradient generated by $Na^+$/$K^+$-ATPase. E.g. reabsorption of glucose within the kidneys.

Note:
Glucose transporter type 4 (GLUT-4), also referred to as solute carrier family 2, facilitated glucose transporter member 4, may be a protein encoded, in humans, by the SLC2A4 gene. GLUT4 is an insulin-regulated glucose transporter found primarily in adipose tissues and skeletal muscle (skeletal and cardiac).
