Glucose provides energy for cells. different cells have different mechanisms for glucose intake. intestinal cells contain proteins that transport glucose against its concentration gradient. these proteins couple the movement of glucose to the movement of sodium down its concentration gradient. red blood cells have transporter proteins embedded in their membranes. when bound by a glucose molecule, these proteins change shape and allow glucose to move down its concentration gradient into the cell.

based on this information, what type of transport is used for glucose in blood and intestinal cells?

From the given information, the transport of glucose in blood across the red blood cells takes place by facilitated diffusion, that involves the spontaneous passive-transport with the help of trans-membrane proteins or transporter proteins to move the ions or molecules down the concentration gradient.

While the transport of glucose in intestines take place via active transport mechanism. It takes place from gut into intestines. It occurs against the concentration gradient with the help of energy molecules like proteins.

after a the power stroke, adp is released, but the cross-bridge formed is still in place. atp then binds to myosin, moving the myosin to its high-energy state, releasing the myosin head from the actin active site.
