Enzyme Study Questions 1. Definitions/terminology: o enzyme: a protein molecule that catalyzes chemical reactions without itself being destroyed or altered o catalyst: a substance that increases the rate of a chemical reaction but is not consumed or changed by it. o substrate: a substance upon which the enzyme acts. o denaturation: the partial or total alteration of the structure of a protein without change in covalent structure by the action of certain

Experiment 2 Quantification of Proteins in Solution by Spectrophotometer Lab bench# 1 Introduction: Absorption spectroscopy is a common method for finding the concentration of proteins or protein complexes in a solution. Proteins absorb light at specific wavelengths and can be defined by the equation A = log (Io/I). This equation states that an absorbance at a specific wavelength‚ A is equal to the log of the ratio of incident light intensity (Io)‚ to transmitted light intensity (I). A

Student number: 1701974 Unit code: BHS004-1 Assessment number: 2/5 Word count: You were given five samples of patients’ urine and some Uristix® dipstick. Describe how you used the dipsticks to determine if urine sample contained amounts of protein and / or glucose. To test the given samples for glucose or protein‚ dipsticks were immersed into each of the urine samples for 60 seconds. The colour change was compared with the colour chart on the Uristix® bottle. The detection of glucose in urine

After 48h hours‚ i.e. on 10th day‚ an hour after test drug administration the animals were sacrificed and blood was collected from retro-orbital puncture. The blood was allowed to clot and the serum was separated for biochemical estimations. The kidney was dissected out‚ kept in 10% formalin and used for antioxidant and histological examination. Assessment of renal

present in serum or specific antisera. ■ Field serum samples are serially diluted in P.B.S & allowed to react with standard antigens (4 HA). ■ Half an hour is given to the reaction so that antigen and antibody may react. ■ 1% R.B.Cs are added to evaluate the Haemagglutination inhibition. ■ Serum samples containing specific antibodies against the antigen used will inhibit the haemagglutination activity of the virus. ■ Reciprocal of the last serum dilution causing

bubbles. After this was finished and the egg was decalcified‚ the egg felt soft. It also felt easier to hold because it could adjust its shape to my hand. The egg was left without a shell after the decalcifying process. The only thing left holding the albumin in place was the egg membrane‚ it is comparable to the plasma membrane found in eukaryotes. The egg membrane was also partly see-through; This allowed me to make out the nucleus of the egg. It took up most of the viewing point of the egg‚ but I was

Blood‚ cerebrospinal fluid (CSF) and brain tissue are all constituents of the cranium. The pressure within the cranium is known as intracranial pressure (ICP); it is the same as that found in the brain tissue and CSF. (2) The pressure-volume relationship between ICP‚ brain tissue‚ blood‚ volume of CSF‚ and cerebral perfusion pressure (CPP) is known as the Monro-Kellie hypothesis.(12) This hypothesis states that the cranial compartment is considered as an enclosed and inelastic container‚ which has

PURIFICATION OF LACTATE DEHYDROGENASE FROM CHICKEN MUSCLE TISSUE Abstract The enzyme lactate dehydrogenase (LDH) catalyzes the last step of anaerobic glycolysis that is important for the normal function of the body. Purification of LDH is essential to understand its structure and function. The purpose of this experiment was to extract and purify LDH enzyme from chicken muscle tissue using a variety of various. Analytical methods such as activity and protein assay were employed to determine

Physio-EX Blood Analysis: Computer Simulation Introduction In this lab five blood tests will be performed: hematocrit determination‚ erythrocyte sedimentation rate‚ hemoglobin determination‚ blood typing‚ and total cholesterol determination. A “hematocrit refers to the percentage of red blood cells (RBC’s) in a sample of whole blood. Since the function of red blood cells is the transport of oxygen to the cells of the body‚ the higher the hematocrit‚ the more red blood cells are available to carry
