BIOLOGY ACTUAL EXAM 2026 QUESTIONS
WITH COMPLETE SOLUTIONS GRADED A+
⩥ What do carbohydrates do? Answer: provide energy, in the form of
sugars like glucose and fructose, but they also make up structures like
cellulose, which form the cell wall of plant cells
⩥ What type of carbohydrate is the most important source of energy?
Answer: mono-, di- and poly-saccharides
⩥ What are mono and disaccharides? Answer: polar and soluble in water
⩥ What are polysaccharides? Answer: Macromolecules resulting from
polymerisation (condensation) of sugars and are not soluble in water
⩥ Examples of monosaccharides Answer: ribose, glucose, fructose,
galactose
⩥ What forms a disaccharide? Answer: two monosaccharides linked
together by condensation reactions with glycosidic bonds releasing one
H2O molecule
,⩥ Alpha glucose structure Answer:
⩥ Beta glucose structure Answer:
⩥ Examples of Polysaccharides Answer: cellulose, glycogen and starch
⩥ Monomer of Sucrose Answer: glucose and fructose
⩥ monomer of maltose Answer: glucose and glucose
⩥ monomer of lactose Answer: glucose and galactose
⩥ monomer of starch Answer: glucose
⩥ monomer of glycogen Answer: glucose
⩥ monomer of cellulose Answer: glucose
⩥ In animals, what carbohydrate stores energy? Answer: glycogen
⩥ What jobs do carbohydrates have other than storing energy? Answer:
structural components
, ⩥ What differs the polysaccharides all made up of glucose? Answer:
they differ in the arrangement of glucose molecules and position of the
glycosidic bonds
⩥ Starch arrangement Answer: amylopectin branched, amylose linear
⩥ What is galactose? Answer: a sugar in milk
⩥ What is fructose? Answer: a sugar found in fruit and honey
⩥ Main characteristic of lipids? Answer: little to no affinity to water,
mostly hydrophobic
⩥ What are the simple forms of lipids? Answer: fat, oil and wax
⩥ What are lipids characteristics in different solvents? Answer: they are
non-polar and insoluble in water, but soluble in organic solvents
⩥ What are triglycerides? Answer: the main group of lipids. They are
formed by condensation reactions between one glycerol and three fatty
acids, creating ester bonds
