Which statement describes how the molecular structure of starch is suited to its function?
AAmylose has a branched structure and amylopectin is coiled to give a compact molecule for transport.
BIn the breakdown of amylose and amylopectin, many hydrolysis reactions release stored energy.
CIn the formation of amylose and amylopectin, many condensation reactions allow the release of stored energy.
DThe final amylose / amylopectin complex is insoluble and does not affect the osmotic properties of the cell.
✓ Correct answer
D: The final amylose / amylopectin complex is insoluble and does not affect the osmotic properties of the cell.
