reactions without undergoing a permanent change themselves. These proteins are able to do this by lowering the activation energy of a reaction. To add on‚ enzymes require specific conditions under which they can work best. Reactions occur at faster rates when the temperature is higher. However‚ the rate of an enzyme-catalyzed reaction is reduced or can be stopped if the temperature becomes too high. This is due to the fact that enzymes become denatured at high temperatures. Denaturation occurs when the shape

From his stance on climate change to a rise in xenophobia after his inauguration‚ the effects of Donald Trump and his current presidency of the United States has the power to change the future. The impacts Donald Trump’s decisions have over the next four years during his presidency can have great effects on not only the United States but the future of the world. Firstly‚ one effect Trump’s candidacy has had in the United States is a rise in xenophobia and hate crimes. The news site newyorker.com

The Civil Right Movement is working but not fast enough. There is a lot of violence as a result of the change that is trying to be made. African Americans try to use a non-violent approach but whites just turn it around and make it violent. Its not working fast enough to help anyone. First they tried to use a bus boycott to try and gain themselves more respect and rights. This didn’t work as well as they hoped because blacks didn’t really come out with everything they wanted. The boycott ended up

reaction than the other test tube. Which simply contained 10 mL of 3% hydrogen peroxide. The factor that affected the reaction rate was that the manganese was seen as a catalyst. The reason collision theory relates to this experiment is due to the fact that the catalyst creates a higher activation energy and this causes more collisions‚ which increases the reaction rate. In the second experiment‚ the Alka Seltzer tablet was

To investigate how does the concentration of Hydrochloric acid affect the rate of reaction? Outline I aim to discover how different concentrations of Hydrochloric acid influence the rates of reaction. In order to carry out this investigation I have decided to use marble chips‚ which I will vary the sizes as powder‚ small chips and large chips. I will also be changing the concentration‚ the different concentrations are as follows 0.2m‚ 0.5m‚ 1m‚ 1.5‚ 2m. I have chosen these concentrations as they

On the Kelvin scale‚ 0 degrees is absolute zero‚ the coldest possible temperature. Absolute zero is equal to -273.15 °C or -459.67 °F) A. How does the change in temperature affect the speed of the molecules? __If the temperature is colder the molecules move slower and if the temperature is hotter the molecules move faster.

Science investigation Aim: To try to see if the temperature affects the rate in which Amylase breaks down starch into maltose. In this reaction starch is the substrate and maltose is the product. Amylase is an enzyme‚ Enzymes‚ also called catalysts‚ are in living things and there are thousand of them. Enzymes break down food by the active site on the Enzyme forming a chemical bond with a substrate and then water attacks the substrate until it is hydrolysed (split in 2). Equipment: Boiling

Exploring Rates‚ Equilibrium‚ and Organic Chemistry Brandon Sher SCH 4U For: Ms. Merhai Due date: June 1st‚2013 Introduction: Organic chemistry. Two quantities one could measure with the presence of organic chemicals are chemical equilibrium and rate of reaction. Chemical equilibrium is the ratio between the forward and reverse process of a reaction. This is represented by the equation: K = products / reactants. When a reaction has reached equilibrium‚ the

Is There A Relationship Between Body Temperature and Heart Rate? Statement of Research Question: This study sets out to determine whether there exists a difference in the average body temperature between males and females. Furthermore‚ the study aims to determine whether an increase in heart rate corresponds with an increase in body temperature. Data Collection: The data was obtained from the article “What’s Normal? -- Temperature‚ Gender‚ and Heart Rate” (Shoemaker‚ Allen 1996) as found in
