The competitive inhibitor that was added was lactose. We predicted this because competitive inhibitors block and bind to the active site so it will slow down the binding of the desired substrate. An alternative hypothesis that came up was that the reaction of substrate would stay consistent as if no inhibitor was added. The enzyme could reject the inhibitor if it does not fit in the active site, causing the substrate to bind as it normally would. Our results showed that with the addition of lactose, the reaction did slow down a considerably
Arsenate wastes energy by the uncoupling phosphotransfer reaction so its very POISONOUS. However, glycolysis still proceeds. Arsenate can then also inhibit the conversion of pyruvate into acetyl-CoA, blocking the Krebs cycle and therefore resulting in further loss of ATP.
Proton pump inhibitors (PPIs) are a group of medicines, such as lansoprazole and omeprazole, that work on the cells that line the stomach, reducing the production of acid. The stomach normally produces acid to help with the digestion of food and to kill germs (bacteria). This acid is corrosive so the body produces a natural mucous barrier which protects the lining of the stomach from being eroded. In some people this barrier may break down and allow the acid to damage the stomach, causing an ulcer. In others, a problem may occur with the muscular band at the top of the stomach (the sphincter) that keeps the stomach tightly closed.
The effect of pH on the speed of enzyme interaction with substrate chemicals Hypothesis: About pH: If the pH level is less than 5, then the speed of the enzyme reaction will be slower. About temperature: If the temperature stays the same, then the speed of the enzyme reaction will not be completely affected. Background information: The function of enzymes is to speed up the biochemical reaction by lowering the activation energy, they do this by colliding with the substrate. All enzymes are under the class of protein biomolecule. Amino acids are the basic units that are combined to make up an enzyme.
Your stomach is a hollow organ that holds food whilst it is being broken down by the enzymes. There is also strong acid released by the glands in the lining of the stomach which helps break down food into a more useable form and also aids in the destruction of most ingested bacteria. After the contents have successfully been broken down they are released into the small intestine. The small intestine is a 22 foot long tube that helps to break down the food with enzymes released from the pancreas and bile released form the liver. In this organ the process of Peristalsis is at work, pushing the food further and further through the small intestine towards the colon.
Glucagon also causes the liver to undergo gluconeogenesis, a process that allows it to absorb non-carbohydrates substrate, amino acids, from the blood and convert them into glucose. When the body isn 't provided with the enough nutrients or carbohydrates, body cells turn to fat the storage as a last resort. Glucagon provokes the process of ketogenesis which breaks down fatty acids to release energy and produce ketone bodies as by-product. These ketones are then used by the heart and brain for
Temperatures that are too high denature the enzyme and halt the enzyme’s activity (2). Catalase denatures starts to denature at fifty five degrees Celsius (2). Reactions in the human body produce hydrogen peroxide as a product (1). Since hydrogen peroxide is poisonous to the human body, catalase catalyzes hydrogen peroxide into water and oxygen (2 H2O2 → 2 H2O + O2) (1). According to the collision theory, a reaction can only occur if particles collide with sufficient energy to overcome the activation energy and with correct geometrical orientation (3).
Important Side Effects of Fat Blockers In some cases, people report diarrhea, gas, cramps among other mild to moderate side effects while using a particular fat blocker. Be aware that long-term use of fat blockers could lead to a vitamin deficiency. While taking fat blockers, you also run the risk of preventing good fat from entering the body as well. Early on, the FDA found it necessary to remove carb blockers from the shelves as the side effects caused vomiting and nausea in many users. The makers, of course, replied that it was a result of the supplement doing its job.
Lab Report -- Relationship on Enzyme activity and substrate concentration Research Question: Is the more concentrated the substrate of hydrogen peroxide is, the shorter the time taken for the paper disc to rise from the bottom of the beaker? Aim: The opposite of hull hypothesis Background Information: This experiment aimed to investigate on the relationship of the substrate concentration and enzyme activity. Enzymes are proteins produced by a cell that acts as catalysts to increase the rate of a specific chemical reaction without changing the reaction itself. Under some conditions, substrate will bind to the active site of an enzyme and form an enzyme-substrate complex. The enzyme would fasten the chemical reaction and the substrate will
