What are the most used pieces of equipment in these laboratories? The lecture portion was fine if you have a basic grasp of the science before enrolling, but it is not great for those who are behind the curve in the science they are studying it is hard to ask a question and receive a timely answer. The laboratory segment, on the other hand, was horrible. It was too easy, and did not require that I learn proper laboratory procedure.
Positive;yellow precipitate appeared III. Discussion Diffusion of the molecules in a solvent also depends in the molecular weight. In the experiment,the Prussian blue moved slowly with This is because basically of the fact that the smaller the object, the bigger or larger is its inherent kinetic energy.
The Prussian blue has the molecular weight of The blood cells were not derformed or experienced any change brought about by the solution. This is because the concentration of the solute and solvent is equal in amount, so there is no net movement in the cell thus there is change in the pysiological appearance of the blood cells.
The solution with 0. In cases like this wherein the solute is far less than the solvent inside the cell, it is pushed outside in which the space occupied by the solute previously will be replaced by water molecules thus the cell bulges.
This is basically dangerous to the cells because this may lead to the explosion of the cells. The 1. In this solution the cell will experience "collapse" or will shrink because water will be driven out of the cell because the solute will occupy the space inside.
This is also detrimental to the cell because it may loose the very equlibrium of the cell structure.
WELCOME TO THE BIOCHEMISTRY LABORATORY! This Biochemistry laboratory seeks to model work performed in a biochemical research laboratory. The course will guide you through basic lab techniques, investigations into DNA and enzyme kinetics, an intensive purification and characterization of an unreported protein. welcome to bio chem technology laboratory, inc. p.o. box yonkers, ny May 21, · This experiment is carried on in order to evaluate one of several triglycerides to determine the saponification number. This experiment also been carried out to make soap by the same process called the saponification, using the modern ingredient. The experiment to determine the saponification had been carried out in the fume hood.
Dialysis is made possible by membranes which are semipermeable. In this kind of membrane, it is not totally close because some particles or compounds are allowed to pass through and reach the other side.
But we have to understand that cell membranes are composed of a lipid bilayer, which limits or restricts the diffusion of larger molecules such as the glucose. But nature is witty, proteins and sugars are able to pass through integral membrane proteins known as transporters.
Conclusions Diffusion is the tendency of the solute to spread throughout the solution until the composition is homogenous. One type of diffusion is the passive transport. Passive transport is the diffusion of molecules across a biological membrane that requires no work or energy.
It is through passive transport that oxygen enters the red blood cells in the lungs and carbon dioxide passes them out.
Water crosses membrane also by passive transport. Osmosis is the diffusion of water molecules across a selectively permeable membrane. Dialysis is a biochemical separation that works by selective passage of small molecules through a semi-permeable membrane.
Rate of dialysis depends on area of dialyzers, size of the pores, temperature, electric charges and concentration of solution. Cells in isotonic solution remain normal. In hypotonic, solution it will swell and may lyse. In hypertonic, cells will shrivel.Nov 30, · In the experiment the % NaCl solution was an isotonic.
The blood cells were not derformed or experienced any change brought about by the solution. This is because the concentration of the solute and solvent is equal in amount, so there is no net movement in the cell thus there is change in the pysiological appearance of the blood cells.

Clinical chemistry (also known as chemical pathology, clinical biochemistry or medical biochemistry) is the area of chemistry that is generally concerned with analysis of bodily fluids for diagnostic and therapeutic purposes.
It is an applied form of biochemistry (not to be confused with medicinal chemistry, which involves basic research for drug development).
