Osmosis Lab Report

The movement of water down its osmotic gradient across a selectively permeable membrane is known as osmosis. The difference in the concentrations of solutes on either side of the membrane results in the establishment of an osmotic pressure. Water follows the direction of solutes, this means that in the event where there are more solutes outside the cell than there are inside the cell, water will move from the inside of the cell to the outside in order to establish water balance. When a cell is placed in a solution containing more solutes than present in the cell, the solution is referred to as a hypertonic solution. In a hypotonic solution however, the water moves into the cell as a result of more solutes being present in the cell than outside
To guarantee satisfactory tissue oxygenation, an adequate haemoglobin level must be maintained. The measure of haemoglobin in blood is communicated in grams per decilitre (g/dl). Haemoglobin additionally helps in the transportation of carbon dioxide and hydrogen particles back to the lungs. Haemoglobin has the ability to bind to vaporous nitric oxide (NO) and in addition oxygen. As RBCs go through the slim beds of the lungs or other respiratory organs, oxygen is diffused into the erythrocytes and haemoglobin binds oxygen and NO. Haemoglobin at that point dumps its load in the vessels. There oxygen can diffuse into the body cells. The NO unwinds the dividers of the vessels, enabling them to grow which helps the conveyance of oxygen to the cells. Haemoglobin comprises of four subunits, each with a cofactor called a heme group that has an iron atom centre. The iron is the fundamental part that actually binds to oxygen, in this manner every haemoglobin atom can convey four particles of oxygen. Collaboration among the four subunits of the haemoglobin particle is vital for the productive transportation of O2. The four subunits of haemoglobin bind to oxygen agreeably, the binding of oxygen to one site of the four subunits will improve the probability of the rest of the locales to bind with oxygen as well.
