Question

1. following the digestion of food:

a. glucose travels through helper proteins in the cell membrane.
b. identify this specific type of cell transport.
c. is this active or passive transport?
d. use an arrow to illustrate the movement of glucose molecules
where is the higher concentration of glucose - blood or cell?
△ = glucose molecule

Explanation:

a. Facilitated diffusion (since glucose moves through helper proteins in the cell membrane and down its concentration gradient).
b. Facilitated diffusion (a type of passive transport as it doesn't require energy input and uses specific membrane proteins).
c. Passive transport (because it is moving down the concentration gradient and doesn't need energy like ATP).
d. The arrow should point from the blood (higher glucose concentration) to the cell (lower glucose concentration) as glucose moves down its concentration gradient.

Answer:

a. Facilitated diffusion
b. Facilitated diffusion
c. Passive transport
d. Arrow from blood to cell.
