CAIE A-Level Biology A2 12.2.8 Oxidative Phosphorylation Questions

1 D = ATP synthase / ATP synthetase ;
R ATPase

2 A, B and C= ETC / electron transport chain / electron carriers / electron acceptors ;

plus any five from:

role of, ETC proteins / A, B and C

3 electrons travel along ETC ;

4 energy released ;

5 (use energy released) to pump / actively transport, $\mathrm{H}^{+}$/ protons, into intermembrane space ;

6 increases concentration of $\mathrm{H}^{+}$/ protons (in intermembrane space)/ creates proton gradient ;

role of D

$7 \mathrm{H}^{+}$/ protons, diffuse through, ATP synthase / D ;

8 (from intermembrane space) to matrix ;

9 synthesis of ATP from ADP and Pi ;

10 chemiosmosis;
