PPT-Enzymes T he body is always looking for ways to save energy!

This is where enzymes come into play Help the body do this Enzymes What are they What properties do they have Why do we need them How do they work Enzymes What are they P. Understanding:. Enzymes have an active site to which specific substrates bind. Enzyme catalysis involves molecular motion and the collision of substrates with the active site. Temperature, pH and substrate concentration affect the rate of activity of enzymes. 1 $59.95 Save $30 $59.95 Save $30 $59.95 Save $30 $59.95 Save $30 $59.95 Save $30 $59.95 Save $30 $59.95 Save $30 $59.95 Save $30 $59.95 Save $30 $59.95 Save $30 $59.95 Save $30 $59.95 Save $30 3 BONU Presented by Fotios Patsalis .

Enzymes speed up chemical reactions.. Everything that happens in a cell. Growth. Reproduction. Interaction with the environment. Response to stimuli. Is the result of a chemical reaction.. A chemical reaction is a change in the arrangement. By: Viktoria, . Plamen. , Daniela, Alexander Popov. School for romance languages “. G.S.Rakovki”Burgas. 2016-2017. Content:. HISTORY. WAYS TO HELP THE ENVIRONMENT. SWITCH OFF ELECTRICAL DEVICES WHEN YOU ARE NOT USING THEM. IMPORTANCE. OF ENZYMES. Enzymes are biological catalysts that:. . I. ncrease. . reaction rates . by lowering the amount of energy needed for the reaction to occur. 100-1000x . faster. !!!. Activation Energy. 1. What are enzymes?. Each enzyme has only one specific reaction it can perform. . 2. How many different reactions can a single enzyme perform?. Yes, the same enzyme molecule can be used over and over. protein. !. Enzymes are . Biological . catalysts . that . increase. . the rate of metabolic reactions.. Since enzymes speed up chemical reaction rates, what are they called?. Catalyst- . A substance . . SYFTET. Göteborgs universitet ska skapa en modern, lättanvänd och . effektiv webbmiljö med fokus på användarnas förväntningar.. 1. ETT UNIVERSITET – EN GEMENSAM WEBB. Innehåll som är intressant för de prioriterade målgrupperna samlas på ett ställe till exempel:. Restriction enzymes. Polymerase enzyme. Strand-displacing polymerases. Helicase enzymes. Discovery and Obtainability:. Most enzymes are proteins discovered in cells.. But . DNAzymes. were . descovered. To the penny placed on your desk.. Observe the penny but don’t touch it. What happens?. Explain why. 2. Give the penny a . little . push. What happened?. Why did the penny move the second time and not the first time?. You would have to eat. your body weight if you needed to completely regenerate the ATP for your body. BUT. Enzymes. Chemical Reactions are represented by chemical equations. During chemical reactions, valence electrons of atoms or compounds are rearranged to form a new substance with new properties.. In order for chemical reactions to take place, . enzymes . must be present to help . speed up . the reaction.. Chemical bonds connect atoms. to make . molecules. .. Chemical . reactions. can do two things:. Today’s Objectives. Describe a general enzyme-catalyzed reaction. Discuss the relation of temperature and pH to rate of reaction in an enzyme-catalyzed reaction. Explain how chemical reactions are affected by enzymes.
