ENT Job Interview Questions Table of Contents:
1 :: Explain What is meant by substrates of enzymatic reactions?
Substrates are reagent molecules upon which enzymes act.
The enzyme has spatial binding sites for the attachment of its substrate. These sites are called activation centers of the enzyme. Substrates bind to theses centers forming the enzyme-substrate complex.
Enzyme Activity: enzyme-substrate complex

2 :: Explain What are the main theoretical models that try to explain the formation of the enzyme-substrate complex?
There are two main models that explain the formation of the enzyme-substrate complex the lock and key model and the induced fit model.
In the lock and key model, the enzyme has a region with specific spatial conformation for the binding of the substrate. In the induced fit model, the binding of the substrate induces a change in the spatial configuration of the enzyme for the substrate to fit.

3 :: Explain Which equation gives the relation between specific rate (k) and Temperature?
Arrhenius equation K = Ae-E a / R T
Read More4 :: Explain What is the difference between essential and natural amino acids?
Essential amino acids are those that the organism is not able to synthesize and that need to be ingested by the individual. Natural amino acids are those that are produced by the organism.
There are living species that produce every amino acid they need, for example, the bacteria Escherichia coli that does not have essential amino acids. Other species, like humans, need to obtain essential amino acids from the diet. Among the twenty different known amino acids that form proteins, humans can make twelve of them and the remaining eight needs to be taken from the proteins they ingest with food.
The essential amino acids for humans are phenylalanine, histidine, isoleucine, lysine, methionine, threonine, tryptophane and valine.

5 :: Explain How does the formation of the enzyme-substrate complex explain the reduction of the activation energy of chemical reactions?
The enzyme possibly works as a test tube within which reagents meet to form products. With the facilitation of the meeting provided by enzymes it is easier for collisions between reagents to occur and thus the activation energy of the chemical reaction is reduced. This is one of the explanatory hypotheses.
Read More8 :: Explain What amount of catalyst is consumed in the reaction it catalyzes?
Catalysts are not consumed in the reactions they catalyze.
Read More9 :: Explain Dolomite is the ore of which element?
Dolomite is an ore an element magnesium (mg)
Formula (MgCO3 CaCO3)
Read MoreFormula (MgCO3 CaCO3)
10 :: Explain What are respectively some remarkable functions of myosin, CD4, albumin, keratin, immunoglobulin, reverse transcriptase, hemoglobin, and insulin?
Myosin is a protein that associated to actin produces the muscular contraction. CD4 is a membrane protein of some lymphocytes, the cells that are infected by HIV. Albumin is an energy storage protein and an important regulator of the blood osmolarity. Keratin is a protein with structural function present in the epidermis and skin appendages of vertebrates. Immunoglobulins are the antibodies, specific proteins that attack and inactivate strange agents that enter the body. Reverse transcriptase is the enzyme responsible for the transcription of RNA and formation of DNA in the life cycle of retroviruses. Hemoglobin is the protein that carries oxygen from the lungs to the cells. Insulin is a hormone secreted by the pancreas that participates in the metabolism of glucose.
