Blank | Term |
1 | Complement proteins |
2 | Interferons |
3 | Lymphocytes |
4 | Antibody |
5 | B cells |
6 | Helper T cells |
7 | Cytotoxic T cells |
8 | Memory cells |
9 | Immunization |
Explanation of Solution
Complement proteins are responsible for enhancing phagocytosis and binding better to the pathogens. IT activates the phagocytes by binding and results in the destruction of pathogen external membrane.
Interferons are the proteins secreted by the infected cells that bind to cell nearby it and stimulates the cells to release antiviral proteins.
Lymphocytes are a type of white blood cell, which is involved in the immunity and are matured in bone marrow.
Antibodies are the proteins that specifically reacts to the pathogens. The B cells are chief producers of the antibodies.
The T Helper cells aids in the killing of microbes and activate the B Cells for the secretion of antibiotics.
Cytotoxic T cells are responsible for destruction of the pathogens and they also release cytokines.
Memory cells are lymphocytes that are long living. They are formed after the primary infection of a pathogen and attacks the pathogen when the body encounters ssame pathogen again.
Immunization is a process, in which an antigen is inserted in the body in order to elicit a primary immune response. This primary response result in formation of memory cells, so, when the pathogen encountered again, the secondary response kills the pathogen more effectively.

- A sample of blood was taken from the above individual and prepared for haemoglobin analysis. However, when water was added the cells did not lyse and looked normal in size and shape. The technician suspected that they had may have made an error in the protocol – what is the most likely explanation? The cell membranes are more resistant than normal. An isotonic solution had been added instead of water. A solution of 0.1 M NaCl had been added instead of water. Not enough water had been added to the red blood cell pellet. The man had sickle-cell anaemia.arrow_forwardA sample of blood was taken from the above individual and prepared for haemoglobin analysis.

The difference in the spectra is due to a pH change in the deoxy-haemoglobin due to uptake of CO2- 2. There is more oxygen-carrying plasma in the oxy-haemoglobin sample. 3. The change in Mr due to oxygen binding causes the oxy haemoglobin to have a higher absorbance peak. 4. Oxy-haemoglobin is contaminated by carbaminohemoglobin, and therefore has a higher absorbance peak 5. Oxy-haemoglobin absorbs more light of blue wavelengths and less of red wavelengths than deoxy-haemoglobinarrow_forward

It has two alpha subunits and two beta subunits. The subunits are joined by disulphide bonds. Each subunit covalently binds a haem group. Conformational change in one subunit can be transmitted to another. There are many variant ("mutant") forms of haemoglobin that are not harmful.arrow_forwardWhich ONE of the following is FALSE regarding haemoglobin? It has two alpha subunits and two beta subunits.
