Hi, does anyone have the following question:

Draw phospholipids on figure 2 to show how the carrier protein, SGLT1, would fit into the cell surface membrane.

I think it is from the 2020 A Level paper, it is in the assessment material released today, but I don't have figure 2.

Can’t find it either. I’m guessing we just draw a carrier protein in a phospholipid bilayer.

Not sure if it's 100% right but:Na moving out of cell creates a concentration gradient as the concentration of Na ions inside the cell is now lower than the concentration outside the cell. This allows Na ions from outside the cell to move in via co-transport along with glucose.*not sure how much detail you have to go into*

You have to draw the phospholipids onto a diagram of the protein
