(a(i))[1]
State the names of the products formed when sucrose is hydrolysed.
(a(ii))[4]
With reference to Fig. 3.1, describe the mechanism by which the enzyme converts the substrate into products.
(a(iii))[1]
Copper ions ($\text{Cu}^{2+}$) inhibit the enzyme sucrase. State which type of inhibition occurs.
(b(i))[2]
Suggest the role played by sucrose in the unloading of sucrose at sinks.
(b(ii))[3]
Plant sink organs convert excess products of sucrose hydrolysis into storage molecules, such as starch. Explain why these hydrolysis products themselves cannot be stored in plant tissue.
