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.

Question 1 
Students found questions 01.1 and 01.2 accessible, with the majority scoring the marks. 
Answering question 01.3 should have involved only simple recall, however only 28% of students 
scored two marks. When describing the role of DNA helicase, many used very simple language, 
such as ‘unwinds’ or ‘unzips’. Such terms were not accepted at GCE level. When describing the 
role of DNA polymerase, the most common mistake was stating that it forms hydrogen bonds 
between bases. The...

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 covers 
the students’ responses to quest...
