Sonia St James Investigation: Factors that affect the outcome of enzyme activity Introduction In this project I will monitor the rate of activity of Catalase. Catalase is an Enzyme which in the right conditions catalyses the decomposition of Hydrogen Peroxide into water and oxygen; 2H2O2 + Catalase >>> 2H2O + O2 Catalase is found in all cells and protects them from Hydrogen Peroxide which is a dangerous waste product that needs to be eliminated. Without Catalase living things could not survive

Biology Coursework: Preliminary Work 8/12/2013 Intro I am going to investigate a factor that affects the rate of enzyme activity What are enzymes and how do they work? Enzymes are biological catalysts - catalysts are substances that increase the rate of chemical reactions without being used up. Enzymes are also proteins and thus have a specific shape. They are therefore specific in the reactions that they catalyse - one enzyme will react with molecules

Describe how igneous activity can affect the landscape Igneous intrusions form when cooling‚ crystallization and loss of gases cause a once fluid magma to solidify. Most rocks that form intrusions originate as either granitic or basaltic magma. Granitic magmas are low density and small quantities‚ just a few kilometers wide‚ rise slowly through the earth’s upper crust‚ pushing existing country rock aside. However‚ very large granite masses‚ which can be up to 1‚000 times larger‚ are formed when magma

Testing and assessment is the process of determining the extent to which students achieve instructional objectives. It is a scheme for collecting evidence of what learners accomplish through process of teaching and judge the direction and extent of changes. Testing is a continuous process and forms an integral part of the total system of education and in vary closely related to educational objectives. The purpose of this evaluation is to make provisions for guiding the growth of the learners to

children deal with learning problems which are first noticed by parents and teachers at home or school. A learning disability or a learning disorder is a neurological disorder that can interfere with the use of listening‚ speaking reading‚ writing‚ spelling‚ reasoning‚ or mathematical skills. Researchers believe that learning disabilities are caused by a difference in the way a person’s brain works and processes information. The wiring of the brain is affected in children with learning disabilities where

Week 7 Learning Activity 1. Was the relationship among Grace and her sons a partnership for a term or a partnership at will? Grace Tengalhat and her sons‚ Manny and Jason verbally agreed to share the business for five years. “Partnership for a term is a partnership that exists for a specified duration or until a specified event occurs‚” (uslegal.com)‚ since they agreed for five years‚ this is a partnership for term. A partnership at will is when a partnership is made with no fixed term. 2. Did

Enzymes are catalytic proteins that selectively speed up chemical reactions without by consumed by the reaction itself (1). Enzyme activity is significantly affected by factors such as temperature‚ substrate concentration‚ enzyme concentration and pH. Enzymes are highly specific and only catalyse one specific chemical reaction‚ speeding up the reaction by lowering the activation energy‚ the energy required to start a chemical reaction (2). At high temperatures and with various mechanical forces or
