Practise IB Biology SL B1.1.4 by comparing ribose and glucose, explaining glucose's transport and respiratory role, and relating carbon 1 to alpha/beta forms.
Insect pollinators are vital to maintaining the biodiversity of ecosystems, but they are threatened by some human actions. Some pollinators, such as honey bees (Apis mellifera), produce honey, which is rich in glucose.
Outline how the properties of glucose are linked to their uses in organisms.
a. soluble (in water/blood) SO it is easily transported;
b. glucose is (easily) oxidised/used to produce ATP in (cell) respiration;
c. has high energy bonds/energy rich / is a source of (chemical) energy;
d. energy/ATP is used in muscle contraction/active transport/any correct biological answer;
e. can be polymerized (by condensation) SO can be stored;
f. can be converted into glycogen/starch/cellulose;
g. polymers easily broken down so energy/glucose can be released;
For b. do not accept Glucose "produces" energy alone
For e. accept descriptions of polymerization
