For polysaccharides to be fully hydrolysed, every glycosidic bond joining the monomers must be broken. Enzyme X hydrolyses only $\alpha$-1,4 glycosidic bonds. Which row indicates how far enzyme X is able to hydrolyse glycogen and amylose molecules?
- Aglycogen: +, amylose: ++
- Bglycogen: ++, amylose: +
- Cglycogen: ++, amylose: -
- Dglycogen: -, amylose: +
