... The fibrous proteins are the proteins that hold many of the living structures together. Examples of fibrous proteins are elastin, collagen, keratin, actin and myosin. All fibrous proteins have different structural properties, which suit it to the role it plays ...

... oncolytic virotherapy by describing the main strategies used, and why this technique would be advantageous compared to the existent treatments for cancer. The idea that a virus could help in killing cancer cells began in 1912, when an Italian ...

... and more complicating viruses as spider shaped. Viruses are not like cells or bacteria as they do not contain " Chemical Machinery " enzymes but only have one or sometimes two enzymes which simply decode their genetic instructions. This means the ...

... obtain a value for the size of a single polymer molecule in solution and to therefore deduce its conformation. 2) To show and measure the dependence of polymer solution viscosity on concentration. Viscosity is the property of a fluid that causes a ...

... down glucose into alcohol, producing carbon dioxide as shown in this simplified equation: C6H12O6 2C2H5OH + 2CO2 + energy This reaction is exothermic as energy is given out. It takes place in the cytosol of the cytoplasm within the yeast cell. The ...

... a fruit juice can be estimated using a blue chemical die called DCPIP (common name 2,6-dichlorophenolindolephenol). It is reduced by an equal amount of vitamin C to a colourless, or sometimes pink, compound solution. This experiment will aim to find ...

... stress; a substrate for ascorbate peroxidase; and an enzyme cofactor for the biosynthesis of many important biochemicals. Vitamin C acts as an electron donor for eight different enzymes: The vast majority of animals and plants are able to synthesize their ...

... oxygen produced as the catalase reacts with the hydrogen peroxide. Variables The only variable that there is going to be in this experiment is going to be the concentration of the liquidised celery; this will be changed in proportion to ...

... that osmosis occurs through the partially permeable membrane. Explanation -Particles can only react when they collide. -Heating a substance causes the particles to gain more kinetic energy. -This causes the substrates to bind and collide more frequently with the active site of the ...

... a more accurate estimate at what exact temperature the cell wall melts. My graph shows a decrease of transparency in the water between the points of 60?C and 70?C. From this I can make the prediction that between these two ...

... very much energy. Molecules need to interact with enough energy in order to react. When the temperature is low there is not enough energy for the molecules to react. As a result the rate of reaction is reduced. B. At this ...

... enzyme has a small section called the 'active site', which is the exact shape to fit around the substrate molecule; this is called 'the lock and key hypothesis'. The substrate fits into the active site to temporarily form an 'enzyme-substrate ...
