Glucose Transporter (GLUT) How Does it Work

The video explains the glucose transporter system, focusing on facilitated diffusion. It introduces the GLUT transporters, which move glucose down its concentration gradient without energy input. The process involves glucose binding to a transporter protein, causing a conformational change that allows glucose to exit the cell. Different GLUT transporters serve various functions in different cell types, such as muscle and liver cells.

What is the abbreviation used for glucose transporters?

• GLU

• GTP

• GLUT

• GCT

How does glucose move across the cell membrane in the described transport process?

• Down its concentration gradient

• Through simple diffusion

• With the help of ATP

• Against its concentration gradient

What type of transport is involved in moving glucose into the cell?

• Active transport

• Facilitated diffusion

• Osmosis

• Simple diffusion

What happens to the glucose transporter protein when glucose binds to it?

• It becomes inactive

• It releases energy

• It changes conformation

• It breaks down

Which GLUT transporter is likely to be found in muscle cells?

• GLUT 1

• GLUT 2

• GLUT 3

• GLUT 4
