What is the primary function of co-transport of glucose in the ileum?
to secrete glucose into the lumen from the bloodstream
to absorb glucose from the lumen into the bloodstream
to store glucose in the ileum for later use
to break down glucose into simpler molecules
|
Which protein uses active transport in the co-transport of glucose?
|
Which of the following proteins use facilitated diffusion in the co-transport of glucose?
(Select all that apply)
sodium-potassium pumps
glucose protein channels
sodium-glucose co-transporter proteins
|
What happens to the concentration of glucose in the lumen during co-transport in the ileum?
it fluctuates
it decreases
it increases
it remains the same
|
What is the role of ATP in the co-transport of glucose in the ileum?
it is not involved in co-transport of glucose in the ileum
it is used to maintain the concentration gradient of sodium ions between the lumen and the epithelial cells of the ileum
it is used to transport glucose from the lumen of the ileum to the epithelial cells
it is used to transport sodium ions from the epithelial cells to the lumen of the ileum
|
What happens to glucose after it is transported into the epithelial cells in the ileum?
it is stored in the epithelial cells for later use
it diffuses from the epithelial cells into the bloodstream
it is broken down into smaller molecules in the epithelial cells
it is converted to glycogen in the epithelial cells
|
Which protein uses active transport in the co-transport of glucose?
sodium-potassium pump
none of the proteins use active transport
glucose channels
glucose co-transporter
