Biology A Level 2020 Exam Question

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.

Hi, they are here - https://www.aqa.org.uk/subjects/science/as-and-a-level/biology-7401-7402/assessment-resources.

They are near the bottom as word documents.

Did anyone figure out where to actually draw the carrier protein in question 01.4? Im so confused like do I draw on the diagram(I don't know where that would fit tho) or beside the diagram?? 😩

Hey! you can access all the questions on the aqa website. Its part of the 2021 assessment materials that was released
lol does anyone have the markscheme for the aqa bio paper ?
Does anyone know the answer for the q on biological molecules/cells aqa a level bio about Na+ moving out of cell by absorption ?
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
