Is the OH above or below in a alpha-glucose?
Below.
1 of 12
Is the OH above or below in a beta-glucose?
Above.
2 of 12
What is the general chemical formula of glucose?
C6H10O6
3 of 12
What 3 characteristics do monosaccharides share?
Sweet tasting, soluble and form crystals.
4 of 12
Is maltose a monosaccharide, disaccharide or polysaccharide?
It is a disaccharide sugar.
5 of 12
Which form of glucose is not respired by animals and why not?
Beta-glucose because of it's structure, the enzymes within the body are not complementary to beta-glucose.
6 of 12
What is the bond between glucose molecules in amylose called?
Glycosidic bonds.
7 of 12
Why are starch and glycogen useful storage molecules?
Why are starch and glycogen useful storage molecules?
8 of 12
How is the energy stored in glycogen accessed when it is needed?
Through hydrolysis reactions catalysed by enzymes to produce glucose.
9 of 12
Describe the arrangement of glucose chains in cellulose.
About 60-70 cellulose molecules become cross-linked by hydrogen bonds to from bundles called microfibrils. These, will also form hydrogen bonds to form even bigger bundles called macrofibrils.
10 of 12
How does the arrangement of cellulose provide structural stability?
Macrofibrils run in all directions criss-crossing the wall for extra strength.
11 of 12
Name 2 further structural polysaccarides.
Chitin; which forms the exoskeleton of insects. And peptidoglycan which is the basis of the cell walls found around most bacterial cells.
