Essays GRADE A+ SOLUTIONS
The structure and function of carbohydrates
1) Monosaccharides: glucose, fructose, galactose
2) Disaccharides: condensation / hydrolysis / glycosidic bonds
3) Energy source (e.g. glucose, fructose, galactose released via
respiration)
4) Respiration - use of carbs

6) Polysaccharides
7) Starch
8) Glycogen
9) Structural e.g. cellulose
10) Transport e.g. sucrose in phloem
11) Food store e.g. lactose in milk, starch in plants, glycogen in
animals.
12) Glycoproteins, glycolipids
13) Homeostasis
14) DNA/RNA (pentose)
The importance of shapes fitting together in cells and organisms
1) Enzyme properties and digestion
2) Protein structure
3) Plasma membrane structure and cell transport
4) Antigens, antibodies, B cells & T cells
5) Vaccines
6) Structure of DNA
7) DNA Replication (not PCR)
8) Transcription & translation

10) Restriction enzymes
11) Haemoglobin
12) Action potentials & synaptic transmission
13) Muscle contraction
14) Control of blood glucose
concentration
Describe how the structures of different polymers are related to
their functions
1) Biological molecules - carbs/proteins
2) release of energy from carbs
3) control of blood glucose
, 4) enzymes
5) DNA - structure
6) principles of immunology
7) transport of respiratory gases
The importance of hydrogen bonds in living organisms
1) passage of water through a plant - cohesion-tension mechanism
2) structure of proteins/starch/carbs
3) enzymes
4) DNA

inorganic sources
6) DNA
7) fertilisers and plant growth
8) hydrogen ions affect pH
9) factors which affect enzyme action
