Protein Denaturation

Protein denaturation When a solution of a protein is boiled, the protein often becomes insoluble, that is, denatured, and remains insoluble even when the solution is cooled. Heat denaturation of egg white proteins, such as when boiling an egg, is an example of irreversible denaturation. The denatured protein has the same primary structure as the … Read more

Positive and Negative Feedback

Feedback is defined as information obtained about a reaction to a product, which will allow modification of the product. Feedback loops are thus the process by which a change in the system results in an alarm that will trigger a certain outcome. This result will increase the change in the system or reduce it so … Read more

Exchanging Oxygen and Carbon Dioxide

Summary The binding and buffering of O2 and CO2 in the blood influence their exchange in the lungs and tissues and their transport through the circulation. To investigate binding and buffering effects, a model of gas exchange between blood and tissue is used. The model of exchanging Oxygen and Carbon Dioxide explains haemoglobin saturation, the … Read more
