    bacterial infections. They work by either killing the bacteria or by stopping them dividing and growing. Some work by interfering with enzymes that are essential in the replication of genetic material (either DNA or RNA) in the bacterial cells or in protein synthesis. Some work just by blocking the sites where enzymes usually join to the substrate‚ so they can’t join on and catalyse the reaction. The parent DNA molecule unravels itself and becomes 2 individual strands that stand on either end. The two

    transmission decreases at a steady rate‚ until it reaches pH 8 where there is a steep increase from 30% to 39% as the enzyme has reached its optimum pH at 8. During the experiment in the boiling tube this pH had the deepest red colour as the most protein gelatine was broken up. This meant that in the colorimeter when testing to see what the light transmission‚ this pH let the least light through. For this enzyme as the pH increases the percentage of light transmission decreases until it gets to pH

Blood travels round the body faster‚ delivering nutrients faster‚ so the animals have a higher metabolic rate. 1.1.2 Arteries and veins contain collagen: a tough‚ fibrous protein to make them tough and durable. The artery wall stretches as blood is pumped in and then recoils as the heart relaxes. Blood flow is continual and there is a pulse. Contracting muscles and low pressure in the chest when breathing in assist

    are present in a protein‚ in this case gluten. Introduction: Proteins are large biological molecules that are made up of amino acids. They serve as building blocks that form organic structures such as tendons‚ muscle‚ and cartilage. Enzymes - biological catalysts that allow important chemical reactions to occur in our body - are also made up of proteins. Thus‚ proteins play a fundamental role in the processes of life. [1] Protein purification is basically isolating a protein from complex mixtures
