Compare the blood component (in the blood sample) of a normal person and that of a person suffering from leukemia disease (eg: size, shape, number etc)

Low red blood cell count, platelets and neutrophils. In the case of normal cells they show the different stages of development, while in leukemia the cells stop during the initial stages of development. However, both the shape of the cells in the case of healthy people against people with leukemia are similar.

Explanation:

Leukemia appears as a result of mutations in the DNA of a cell in the bone marrow in full development. When the bone marrow cell mutates in a leukemic cell, it begins to multiply many times. These mutated cells are known as leukemic blasts, and they don't work well. Its presence precludes the production of normal cells. As a result, the amount of healthy cells, such as red blood cells, white blood cells and platelets, is much smaller than normal.

In healthy people the nuclei of the cells are circular in shape and others in the shape of a horseshoe, showing the different stages in cell development. However, in people with leukemia, leukemic blasts stop their development in the early stages. But, these cells have an almost equal appearance in contrast to normal cells.

enzyme active site and substrate specificity

enzymes bind with chemical reactants called substrates. there may be one or more substrates for each type of enzyme, depending on the particular chemical reaction. in some reactions, a single-reactant substrate is broken down into multiple products
