Enzyme Questions Essay Example

Experiment #1
1. At substrate concentration, the enzyme is working at “maximum efficiency.” With a concentration at 40, it produced 2,339 products.
2. The maximum velocity of a reaction is reached when the active sites are almost continuously filled. Increased substrate concentration after this point will not increase the rate. The reaction rate increases as substrate concentration is increased. It will soon level off though.
3. When the concentration is at low substrate, most of the enzyme molecules are not filled since there are low concentrations of substrate. As the result, the substrate is filling in the enzyme molecules which cause it to rise in a straight line.
Experiment #2
1. No enzyme activity is present at low temperature. This is because at low temperatures, the enzymes do not function. The only time they will function is at suitable temperatures, or they become denatured.
2. Enzyme activity is present from 10 degrees Celsius and 20 degrees Celsius. This levels off when it reaches around 30 degrees Celsius because the temperatures are becoming too high. When the temperature becomes too high, it becomes denatured.
3. At low temperatures such as 0 degrees Celsius, there is no enzyme activity since there is no energy to promote activity. Yet, there is an increase of activity when the temperatures are from 10-20 degrees Celsius. However, at high temperatures, there is no enzyme activity. The temperatures cannot be too high or too low for activity.
4. At very high and very low temperatures, there are no products produced. This is because there is no energy at low temperature to catalyze activity. Inversely, at high temperatures, the temperatures are too high which cause an enzyme deformity.
5. For this enzyme, the optimum temperature is between 10-20 degrees Celsius. This is where enzyme activity exists.
6. For human temperatures, an optimum temperature is between 35-40 degrees Celsius.
7. Non-enzyme catalyst will not produce products

    DIGESTIVE ENZYMES AND THEIR FUNCTIONS Mouth -the oral cavity or the mouth contains salivary glands that secrete a wide range of enzymes to aid the first step of metabolism of food. The salivary gland secretes the enzyme lysozyme which has an antibacterial action. The enzymes secreted by the mouth mainly provide protection against bacteria. Betaine helps to maintain a fluid balance inside the mouth. The lists of digestive enzymes secreted by the oral cavity are mentioned in the table. Enzymes | Function…

    Enzymes Enzymes are the sparks that start the essential chemical reactions our bodies need to live. They are necessary for digesting food, for stimulating the brain, for providing cellular energy, and for repairing all tissues, organs, and cells. There are three types of enzymes: metabolic enzymes, digestive enzymes, and food enzymes. Metabolic enzymes catalyse, or spark, the reactions within the cells. The body's organs, tissues and cells are run by metabolic enzymes. Without them our bodies…

    Jennifer Anatomy and Physiology Enzyme Lab Report Introduction The chemical reaction that is being studied is the hydrolysis of starch. The enzyme that is being studied is amylase. This experiment is looking at the effect of temperature on the rate of the enzymatic hydrolysis of starch. My hypothesis is that the higher the temperature the faster the hydrolysis of the starch would occur. The rationale behind this is that heat…

    Laboratory 2: Scientific Methodology & Enzyme Activity Objective: The purpose of this experiment was to simply measure oxygen production rates released from decomposed hydrogen peroxide under different conditions (concentration of enzymes, temperature, and PH level). Hypothesis: Part a: If different amounts of enzyme solution are added to the hydrogen peroxide, then the highest amount of enzymes will have the greatest reaction rate because enzymes catalyze reactions, meaning more oxygen…

    What is Enzyme? Enzymes are protein that acts as speed up reactions and break down molecules in our body. However, different enzymes only work on certain types of molecules. Enzymes can accelerate the reactions by more than one million times.(3) In our human body, there are a total about forty thousand types of enzymes and each catalyzes different kind of molecule.(3) The molecules that enzymes help to accelerate is called substrates, and when enzyme is combined together with the substrate, it…

    reaction involves enzymes. So to understand how bleach works, we first understand how enzymes work. Enzymes Enzymes are the most important thing in our lives, it makes the world go ‘round! Enzymes are proteins that acts as catalysts and help combine or break down hydrogen peroxide. Imagine a pen with ink inside it, when you write, ink comes out, right? You can draw, you can write, then when you finish and get your pen off of the paper, the ink stops coming out. Enzymes are like that, they…
