Enzyme Activity How does temperature affect enzyme activity? In this practical investigation‚ my aim is to discover how temperature will affect enzyme activity‚ by looking at the rate of reaction. I predict that the higher the temperature will be‚ the faster the reactions take place. However‚ I also think that there will be an optimum temperature‚ at which the reaction will work at its fastest; if the temperature goes beyond that‚ the reactions will stop altogether as the enzymes would have

Technology has utterly changed the way of America’s society is and how people interact with others. Since the ever thriving technology was invented‚ cyber bullying has regularly occurred as a consequence of technology which can recurrently result in suicide or suicidal attempts. Today‚ people argue whether if technology truly affects the suicide rate for college students. Essentially‚ everyone who is in college has some type of technology and/ or have at least gone on a social media website previously

affecting reaction ratesProcedure A: Effect of ConcentrationAim: To investigate how the concentration of a reactant affects the rate of reaction. Hypothesis: The more concentrated the reactant‚ the faster the rate of reaction. Materials: 2M hydrochloric acid solution‚ magnesium wire‚ distilled water‚ 4 test-tubes‚ measuringcylinder. Procedure:1)10mL 2M hydrochloric acid solution is poured into a test-tube using a measuring cylinder. 2)A 3cm length of magnesium wire is added to the acid‚ and the

For known amounts of reactants‚ theoretical amounts of product can be calculated in a chemical process. These calculated products are determined using the limiting reagent‚ (the substance that runs out first which stops the reaction) and are called the theoretical yield. The theoretical yield is the amount of product that should be acquired during the experiment if all aspects go perfectly. However‚ due to experimental errors‚ very few labs do so. These results are called actual yield. The percent

individual will also determine how alcohol affects your body. If someone is super skinny and doesn’t eat much‚ but exercises excessively‚ they will more than likely have a very low tolerance for alcohol. They will not be able to drink very much before they are considered drunk. If there is an overweight teenager‚ he may be able to drink more than his friends do before his blood alcohol content goes up high. However‚ just because his body can physically handle more‚ that does not mean that his brain and

Coursework Planning Aim: To find the effect of concentration of thiosulphate on the rate of reaction between sodium thiosulphate and hydrochloric acid. Introduction: Word Equation for the reaction: Balanced Symbol Equation for the reaction: Observations during the reaction: • A yellow precipitate of Sulphur starts to form and the reaction mixture goes cloudy. • A colourless‚ poisonous gas of sulphur dioxide is given off. • Sodium Chloride (salt) and Water also form.

The overall health of the plants that received treatment appeared marginally more deteriorated: stems appear a diminutive in proportion to the control plant. The petioles of the higher concentrations seem shorter. Each plant was removed from its soil and root structure was observed. Upon observation of the roots we noticed a substantial difference in the health as well as the fact that the roots of the plants receiving caffeine. The caffeinated

Group 4 Internal Assessment Partners: Bhavya and Katherine Research question: Does the concentration (mol dm3) of sulphur dioxide in wine rise or fall when exposed to air for different time periods (0‚ 75‚150‚225‚ 300 minutes)? Purpose: Many adults enjoy the consumption of wine but are not aware of the different preservatives and chemicals that are added to the drink. Sulphur Dioxide‚ which is added to many food products including wine because it acts as a reductant‚ is ‘well known as a poisonous

significant physiological effects on your body--one being its direct effect on your heart rate. Features Once consumed‚ caffeine enters your blood from the stomach and small intestine and begins to stimulate your central nervous system. Caffeine stimulates receptors located in cells within your heart to increase your heart rate. Effects of this stimulation speed up your blood flow because of an increase in heart rate‚ as well as an increase in blood sugar‚ urine production and body temperature. Function

Does the PH level of acids in our stomach affect the digestion proteins? Yes‚ if the acidity in my/a stomach is high in terms of the PH balance then the proteins in our stomach will be digested faster because acids are known to breakdown and eat away at many objects. The purpose of this project was to observe how the digestion of protein varies at different pH levels. This project in my eyes helps society by finding the best types of food (i.e. ones with higher/ lower acidity and pH balance)
