Enzymes are biological highly selective catalyst, greatly accelerating both the rate and specificity of metabolic chemical reactions, from the digestion of food to the synthesis of DNA. Enzymes catalyze chemical reactions involving the substrate. Substrate is a molecule that attach to the active site of the enzyme protein which an enzyme acts. Active site is a small port in an enzyme that helps enzyme to bind with substrates and undergo a chemical reaction. During this binding of substrates with active site it creates enzyme substrate complex, which is the complex where the reaction occurs. A small amount of enzyme can alter enormous amount of substrate. But there are lots of factors that could affect the function of enzymes, which are pH, temperature, activators, and cofactors. Also there are inhibitors that inhibits enzymes from doing its job. These inhibitors can be categorized as competitive inhibitor and non-competitive inhibitor. Competitive inhibitor are enzymes that inhibits the molecule from binding to the active site of the enzyme, these inhibitors …show more content…
As you can see according to the figure 4.7, tube 4 that was in a temperature of 4°C took the longest time for the starch to disappear (10 mins 30 seconds). This means that at the temperature of 4°C amylase activity are the slowest, it takes longer for the starch to get digested. On the other hand when amylase was in the temperature of 80°C in tube one, starch disappeared much quicker (1min). This means that amylase acts quicker in a higher temperature. The body temperature for human is between 36°C to 37°C, which means it utilizes digestion of starch rate in a way that's not too fast or too slow. In a molecular perspective the higher the temperature the greater the digestion rate of starch. This experiment well supports the

    Aim: This is an investigation to establish the effect of different temperatures (from 0°C -100°C) on the production of oxygen gas in a potato catalase reaction, using hydrogen peroxide as a substrate. The oxygen gas produced will be measured using a gas pressure sensor. Introduction: Enzymes are proteins, known as biological catalysts that increase the rate of reaction in a biochemical reaction without being chemically altered.…

    A chemical reaction’s rate is described by the amount of product formed. Substances that increase that rate are called catalysts. Catalysts are often proteins called enzymes. Enzymes change the pathway of the reaction between the products and the product. However, enzymes don’t alter the starting or ending points.…

    The temperature is too low inside many living things, which makes it hard for biochemical reactions to happen at a faster rate. Enzymes help biochemical reactions speed up. An enzyme works by lowering the amount of activation energy needed to start a chemical reaction. Activation energy is the minimum amount of energy needed for the reactants to begin a chemical reaction. Normally, biochemical reactions would take many days, but with enzymes doing their job correctly, the same reaction is able to happen in seconds.…

    Enzymes are proteins that act as catalysts and help chemical reactions occur everywhere in life and throughout body. A catalyst is a specific type of protein that increases the rate of a chemical reaction. In an enzyme reaction, the substance that the enzyme acts upon is called the substrate. The enzyme has a special area called the active site, which is a particular point in the substrate at which a reaction occurs. The active site has specific shapes that match up with the enzymes to cause the reactions.…

    Enzymes Two major factors influence how effective an enzyme is by promoting the rate of reaction. Each enzyme has a specific temperature that allows it to perform the most work. If an enzyme is placed in an environment under its optimal functioning temperature, the speed of the reaction will slow. Reason being, the molecules of the reactants reduce in energy from the low temperature, less movement means less reactions with the enzymes. At higher temperatures, molecules within an enzyme increase in rate.…

    The goal of this experiment was to determine the Michaelis constant (Km) and also the maximal velocity (Vmax) and the inhibition of alkaline phosphate. In order to accomplish these goals, 5 samples were used. Each sample contained different volumes of 0.2 m MPNPP (p-nitrophenylphosphate) and 0.2 M Tris-Hcl at a pH of 8.0. To each sample 0.2 mL of the enzyme studied (Alkaline Phosphatase) were added upon insertion on the spectrophotometer apparatus. With intervals of 20 seconds their absorbance at a wavelength of 410 nm was recorded at time frame of 2 minutes for each solution.…

    A major area where enzymes are present a lot in is the food industry. A lot of the food we eat contain enzymes. Lactase is an enzyme that a lot of people know about. It cuts lactose into its smaller sugars: galactose and glucose. When the small intestine of a human does not produce a sufficient amount of this enzyme, this condition is known as the lactose intolerant, which is when a human has discomfort in the form of cramps, gas and diarrhea when they eat/drink milk products.…

    Chemical reactions are vital to living cells. Many chemical reactions take long periods of time to transpire. Enzymes serve as catalysts to speed up biochemical reactions in other substances. Each enzyme interacts with only one specific substrate (molecule) in an organism or a family of related molecules. Enzymes are not changed or used up by the reactions they catalyze, but their effectiveness can be influenced by environmental factors such as the pH level of an environment.…

    For pH, it was hypothesized that the optimal pH would be 7. As temperature was increased, the enzyme activity also increased. Because temperature is the measure of kinetic energy, an increase in temperature would cause an increase in kinetic energy. This means that particles are moving quickly with high entropy, which causes more collisions to happen. Due to this, there is a higher probability of substrates colliding with enzymes, thus making the reaction occur.…

    Abstract: Catalase is an iron porphyrin enzyme present in high concentrations in humans and animals liver tissues. It is a peroxisomal enzyme that is responsible for destruction of toxic H2O2 released during certain metabolic processes. The activity of catalase can be determined by measuring the decrease in H2O2 concentration which is the substrate. Introduction: An enzyme is a large protein that acts as a biological catalyst which changes the rate of a reaction. It provides an active site which is an environment where a reaction can take place this is made up of amino acids.…
