Enzymes All enzymes are globular proteins and round in shape They have the suffix "-ase" Intracellular enzymes are found inside the cell Extracellular enzymes act outside the cell (e.g. digestive enzymes) Enzymes are catalysts → speed up chemical reactions Reduce activation energy required to start a reaction between molecules Substrates (reactants) are converted into products Reaction may not take place in absence of enzymes (each enzyme has a specific catalytic action) Enzymes catalyse

This case study is focused on a company called Vigor Skin Care. Initially known as the “sleeping dog‚” Vigor was barely raking in a profit during its initial years of development. However four years ago‚ Peter Markles‚ the current head of Vigor‚ accepted the challenge of reviving the company. Markles first step in solving this problem was forming a team whose members were committed towards achieving a common goal; bringing success to Vigor. In addition to Markles‚ Sandy Fryda‚ Vigor’s marketing director

Enzyme Lab Report Introduction: Enzymes are proteins that enable chemical reactions. In the enzyme lab‚ the effects of concentration‚ temperature and pH on the functionality of the enzyme catalase. The enzyme lab was also about measuring reactions by capturing the oxygen that was generated by the reaction. Materials and Methods: Experiment 1‚ 2‚ & 3 Experiment 1 examined the effects of concentration on catalase activity. Experiment 2 examined the effects of concentration in temperature

“School can get busy and crazy hectic at times‚ however‚ you must always remember to take a moment‚ breathe deep‚ and remember to take care of yourself. It is easy to forget your persona needs when you have the deadline and that quiz or test coming up to study for‚ you just have to make a little time for you! Also remember‚ there are a lot of great people on this campus that are available to help you. Reach out if there are problems‚ concerns needs or questions. We can not read minds‚ but we

Enzymes are globular proteins that are synthesized by the ribosomes in a cell. They act as catalysts during biological reactions; therefore‚ enzymes are able to speed up these 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

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

Abstract Enzyme catalysis was observed in order to analyze how changes in temperature‚ pH‚ enzyme concentration‚ and substrate concentration affected an enzyme-catalyzed reaction. This experiment analyzed the rate of enzyme-catalyzed reactions and observed the correlation between catalase activity and products formed. It was found out that the rate of an enzyme-catalyzed reaction starts off rapidly‚ decreases‚ and levels off or completely stops‚ and can be further affected by environmental factors
