Unit 1 Topic 1: Lifestyle, Health and Risks
Revision questions
Define the term(s):
1. correlation and causation
1. how monosaccharides join to form disaccharides (sucrose, lactose and
maltose) and polysaccharides (glycogen and amylose) through condensation
reactions forming glycosidic bonds, and how these can be split through
hydrolysis reactions.
2. The differences between saturated and unsaturated lipids.
1. The structure of glycogen and starch – amylose and amylopectin and their role
in providing and storing energy
2. Describe the synthesis of a triglyceride by the formation of ester bonds during
condensation reactions between glycerol and three fatty acids
3. the cardiac cycle (atrial systole, ventricular sytole and diastole)
4. the blood clotting process (thromboplastin release, conversion of prothrombin
to thrombin and fibrinogen to fibrin)
5. the role of the clotting process in cardiovascular disease (CVD).
6. the factors that increase the risk of CVD (genetic, diet, age, gender, high
blood pressure, smoking and inactivity).
7. the benefits and risks of treatments for CVD (antihypertensives, plant statins,
anticoagulants and platelet inhibitory drugs).
1. The dipole nature of water and the importance of this for water acting as a
solvent in transport
2. why many animals have a heart and circulation (mass transport to overcome
limitations of diffusion in meeting the requirements of organisms).
3. how the structures of blood vessels (capillaries, arteries and veins) relate to
their functions.
4. the course of events that leads to atherosclerosis (endothelial damage,
inflammatory response, plaque formation, raised blood pressure).
1. the possible significance for health of blood cholesterol levels and levels of
high-density lipoproteins (HDLs) and low-density lipoproteins (LDLs).
2. how people use scientific knowledge about he effects of diet (including
obesity indicators), exercise and smoking to reduce their risk of coronary heart
3. the consequences of energy imbalance, including weight loss, weight gain,
and development of obesity.
4. The designs of studies used to determine health risk factors (including sample
selection and sample size used to collect data that is both valid and reliable).
5. why people’s perceptions of risks are often different from the actual risks
(including estimating and overestimating the risks due to diet and other
lifestyle factors in the development of heart disease).
