substrate is brought into the catalase and broken apart into water and oxygen. This process may be able to happen naturally‚ but the enzyme‚ catalase‚ speeds up the process.
Premium Enzyme Catalysis Chemical reaction
proteins that catalyze metabolic reactions vital for the survival and functioning of cells [1]. Without enzymes‚ metabolic processes would occur at unfeasible rates. Catalase is a naturally occurring enzyme that breaks down hydrogen peroxide into water and oxygen; it is essential to cellular respiration. I asked if enzyme activity was affected when exposed to different conditions‚ such as temperature‚ substrate concentration‚ and pH levels. My first hypothesis is that higher temperatures amplify

(3). C. Freundii can be located in a wide variety of soils and water (3). Lastly‚ it is also the cause of many nosocomial infections due to its presence in water (1). Identifying C. Freundii holds importance in order to determine infection in gastrointestinal and urinary tracts and in the brain. These infections will often be noticed through pain in these areas. The main purpose of this laboratory experiment was to utilize microscopic and macroscopic observation‚ biochemical tests‚ and antibiotic

The human cardiovascular system consists of the heart‚ the blood‚ and a system of transporting vessels. A human heart has four chambers: a right and left atrium and a right and left ventricle. The fist-sized heart sits in its own sac (the pericardium) in the middle of the chest under the sternum. In most people‚ the apex of the heart points to the left. There are two circuits of simultaneous blood flow in humans: a pulmonary circuit and a systemic circuit. In the pulmonary circuit‚ the right

pressure of the blood. This function is carried out by the kidneys‚ that will filter blood and produces urine through three stages: ultrafiltration‚ reabsorption and secretion. The end product of the process will produce urine‚ which contains mainly water and a range of substances that such as inorganic salts‚ organic compounds and some metabolites. The quantity and composition of the urine reflects various biochemical processes that occur in the body. Thus‚ the composition of the urine of an individual

Wanni Lin Biology 110 March 2‚ 2015 DNA Lab BACKGROUND In this laboratory experiment‚ students were introduced to DNA electrophoresis. DNA electrophoresis is an instrument that many forensic scientists use to get a DNA fingerprint as an evidence for crimes. Not only can it be used for forensic science‚ people can use this for paternity test‚ as well as look for evolutionary relationships among organisms. Agarose is used to make the gel that the DNA fragments are going into. Since DNA particles are
