AQA A-level BIOLOGY 7402/1 Paper 1 Mark scheme June 2022 Version: 1.0 Final. MARK SCHEME – A-LEVEL BIOLOGY – 7402/1 2 Mark schemes are prepared by the Lead Assessment Writer and considered, together with the relevant questions, by a panel of subject teachers. This mark scheme includes any amendments made at the standardisation events which all associates participate in and is the scheme which was used by them in this examination. The standardisation process ensures that the mark scheme...

0 1 Figure 1 shows a cell from the lining of the ileum specialised for absorption of products of digestion. SGLT1 is a carrier protein found in the cell-surface membrane of this cell, it transports glucose and sodium ions (Na+) into the cell. Figure 1 . The action of the carrier protein X in Figure 1 is linked to a membrane-bound ATP hydrolase enzyme. Explain the function of this ATP hydrolase. [2 marks] . The movement of Na+ out of the ce...
