Angiotensin-converting enzyme

Temperatures have a great effect on microorganisms. In the most general sense, bacteria can grow at any temperature between freezing point of water (32°C) and the point where proteins coagulate. Between these two high and low temperatures, each bacteria type has an optimum growth temperature. An optimal growth temperature is the point at which an organism grows best, with optimal cell metabolism. If temperatures creep past the maximum, bacteria are killed. If the temperature drops below the…

nutrients from starch not meat, it states that starch may have played a vital role in human evolution and how humans have more copies of amylase now, which further perceives that amylase may have adapted to changes in evolution overtime. Amylase a vital enzyme, and it plays many significant roles within the body. Professor Alicia, date (…....) discussed that the lower levels of concentration of amylase will have more competition for binding sites, suggesting that higher levels of amylase will…

energy required. An enzyme is a substance produced by a living organism that acts as a catalyst to bring about a specific biochemical reaction. Enzymes carry out the thousands of chemical reactions that occur on cells, or the basic units of structure and function of an organism. Usually, they are polymers of thousands of amino acids. Enzymes are not used up as it carries out the reaction but are recycled over and over. In this experiment, peroxidase from horseradish was the enzyme used to test…

that are the sources of the enzyme catalase. Although the hydrogen peroxide solutions were at the desired temperatures, it was uncertain whether their paired liver cubes had the same temperatures. This places concern on whether the froth height was close to being accurate, hence reliable. If the temperature of a liver were lower than the desired temperature, the enzymes would be less likely to collide to their substrates because according to Sam Adam-Day 2014, enzymes and substrate collide…

Introduction : Enterotube II is used to identify multiple tests in one tube. twelve different conventional media plus a self-contained inoculating wire. The twelve test are for glucose and gas, then lysine, ornithine, H2S and indole, adonitol, lactose, arabinose, sorbitol, dulcitol, phenylalanine (amino acid), urea, and citrate (No VP test require). These medias performs 15 different biochemical tests that will determine the genus and the species of gram negative bacteria. This test will help…

An enzyme is a biological catalyst; they accelerate most reactions within cells (Cooper, 2000). Enzymes have three constitutional characteristics: they assist chemical reactions without becoming exhausted or altered themselves, they do not change the balance between the reactants and products and they are highly specific as to what reactions they are able to catalyse (Cooper, 2000). The active sites of enzymes are where chemical reactions occur. The active sites are dimples or grooves in the…

Experimental Method: Extracting LDH. The LDH used was extracted from bovine skeletal muscle tissue. In the cold room, a mass of 20 grams of muscle tissue was obtained. It was placed in a blender along with ice cold buffer, 50 mM sodium phosphate and 10 mM EDTA at pH 7.5. The mixture was then blended and homogenized in order to break open the cells; during this time the temperature was checked periodically to make sure it stays below 20 C. This was done until the solution was homogeneous. The…

The experiment that the Scientists, listed above, will be performing is about the curdling of milk and how it is affected by pineapple juice, and pineapple enzymes. The Scientists’ problem is whether or not pineapple juice will affect the coagulation (or curdling) of milk. The independent variable in the experiment will be what is added to regular milk (nothing, pineapple juice, or bromelain), the dependent variable will be the speed of the milk curdling. The constant of their experiment will be…

The second test tube 11 was identified as a gram negative bacteria. The biochemical tests that I performed that were positive were catalase, glucose, SIM, indole, citrate, and urea. First, the catalase test has the presence of an enzyme in the test isolated detected using hydrogen peroxide. Bacteria possess catalase with a small number of bacteria; isolation is added to hydrogen peroxide when bubbles occur. When the bubbles occurred on gram positive bacterium it was a conformation of being…

Enzymes are found in all living organisms. They are present to speed up or accelerate a chemical reaction; referred to as a catalyst in a chemical reaction. They are essential to obtain rates to sustain life as without enzymes rates would be too slow to provide for life. Molecules at the start of the process are called substrates, the enzyme will then convert these into changed molecules which are called products, after this process the enzymes maintains the same shape. (Berg et al. 2002).…
