ABPI Practice Test Question Flashcards
Endotoxins and exotoxins are produced by bacteria and are responsible for many of the symptoms of bacterial infection.
Which row A to D correctly shows the characteristics of one of these two toxin types?
A. Exotoxin - lipopolysaccharide - Specific effects such as cell breakdown
B. Exotoxin - soluble protein - General symptoms such as fever and vomiting
C. Endotoxin - lipopolysaccharide - General symptoms such as fever and vomiting.
D. Endotoxin - soluble protein - Specific effects such as cell breakdown
Row D.
Exotoxins are usually soluble proteins which are produced and release into the body by bacteria as they metabolise and reproduce. Some damage cell membranes causing cell breakdown or internal bleeding and other act as competitive inhibitors to neurotransmitters and other directly poison cells.
Endotoxins are lipopolysaccharies, part of the outer layer of gram negative bacteria. tend to cause symptoms such as fever, vomiting and diarrhoea.
Which cell structure is found in both yeast and bacteria?
Select one: A. Vacuole B. Cell wall C. Nucleus D. Capsule
B. Cell wall.
The graph below shows how the activity of an enzyme is affected by temperature.
Use this information to decide which statement below is the best explanation of the cause of hypothermia.
Hypothermia is caused by:
Select one:
A. metabolic enzymes becoming overactive at low temperatures
B. deactivation of metabolic enzymes at temperatures below 20 degrees Celsius
C. low temperatures decreasing the activity of metabolic enzymes.
D. heat destroying the enzymes which carry out cellular reactions
C. low temperatures decreasing the activity of metabolic enzymes.
Schizophrenia is an example of a disease caused by …
Select one: A. mental illness B. genetic factors C. environmental factors D. genetic and environmental factors
D. genetic and environmental factors.
The use of recreational drugs such as cannabis can sometimes trigger mental illness in people who have a genetic tendency to diseases such as schizophrenia.
The symptoms of hay fever are caused by:
Select one:
A. changes in cell membrane permeability due to the release of histamine
B. an immune response resulting in antibody formation
C. mast cells releasing large quantities of mucus
D. antibody release in the nasal mucosa
A. changes in cell membrane permeability due to the release of histamine
Why does a B cell carry out endocytosis?
Select one: A. To extract antigens B. To form a digestive vesicle C. To trigger T helper cells D. To clear away dead pathogens
C. To trigger T helper Cells.
When a B-cell detects and engulfs the same pathogen/antigen it becomes another type of antigen presenting cell.
A T-helper cell from the actice clone produced earlier recognises the antigen presented by the B cell and binds to it.
This triggers the release of cytokines from the T helper cell.

Hormone replacement therapy (HRT) can be used to alleviate many of the symptoms of menopause, including palpitations. In a randomised controlled double-blind study 10 menopausal women experiencing palpitations were randomly assigned to receive either active HRT (n=5) or placebo (n=5). They were then asked to keep a record of the number of palpitation events for a period of two months.
Their results are as follows:
What are the standard deviation values for each group (HRT and placebo)?
Select one: A. HRT = 4.32; placebo = 6.06 B. HRT = 4.32; placebo = 5.42 C. HRT = 4.83; placebo = 5.42 D. HRT = 4.83; placebo = 6.06
Calculating the standard deviation (SD)
- Find the mean value of the data
- Find the difference between each value in the list from the mean
- Square the differences
- Calculate the mean vlaue of the squared differences.
- Take the square root of this mean. This is the SD of the sample.
When Standard Deviations (SD) are calculated, the value of one SD on either side of the mean will include between 60% and 70% of the data. What is the most likely SD for the 15 items in the data shown below? (You are not expected to do a full calculation to find the SD in this question, although that may be required in other questions.)
