Catalyse Guides d'étude, Notes de cours & Résumés

What is dogma in enzymology? - One reaction only has one enzyme to catalyse it What happens during a chemical reaction? - Activation energy provides enough energy for the process to happen where the reactants break or form bonds and create a new product What is transition state? - A less stable state that the products have to go through to get to the final product What is activation energy? - Energy needed to reach transition state and the rate of the reaction depends on how many reaction ...

What type of reactions do organisms need to carry out to survive? - Answer Metabloic Reactions What is a catalyst? - Answer A chemical that speeds up the rate of reaction and remains unchanged and reusable at the end of the reaction What are biological catalysts for metabolic reactions? - Answer enzymes any molecule that can have a reaction catalaysed by an enzyme is called a ... - Answer Substrate What is an enzymes turn-over number? - Answer The number of substrates an en...

What is blebbing correct answers Membrane looses integrity and enzymes are released into peripheral blood Reversible cell damage (mild or large enzyme serum increase) correct answers Mild serum enzyme increase what Is a transferase reaction correct answers Transfers a functional group What is a ligase reation correct answers Joins two molecules What do the proteins in enzymes determine correct answers They determine how the enzymes forms What is the active site correct answers An ...

GCSE AQA BIOLOGY ORGANISATION cell organisation ️similar cells are organised into tissues that perform a function, such as: -muscle -glandular -epithelial different tissues are organised together to make organs that perform a specific function, such as -stomach is made from all of the above organs are organised into organ systems that perform a range of functions -digestive system enzymes ️biological catalysts that control reactions within the body. they are large proteins (long ch...

How are enzymes classified? correct answers Specificity, Classification (By type of reaction) and Composition How does enzyme specificity work? correct answers It is controlled by structural and conformational complementarity (essentially how well it fits) between enzyme and substrate. Name three enzyme classifications based on type of reactions. correct answers Oxidoreductase, Ligase, Transferase. What is a holo-enzyme? correct answers A holo-enzyme is a complex enzyme composed of prot...

Define Enzymes Enzyme is a biological catalyst, which is protein in nature, and can speed up the rate of a chemical reaction, without it being chemically changed at the end of the reaction. How do enzymes work? Enzymes work by lowering the activation energy of a reaction. Activation energy is the minimum amount of energy that reactants must absorb to become activated to start a chemical reaction Properties of an enzyme (7) - Most enzymes are made up of protein - Enzymes alter ...

AQA AS BIOLOGY REVIEW QUESTIONS AND ANSWERS The graph below shows the results of an osmosis experiment investigating the effect of changing the concentration of sodium chloride (NaCl) on mass of potatoes. - ANSWER C - 0.42 mold-3 The reaction between carbon dioxide and water forms carbonic acid. This reaction is catalysed by the enzyme carbonic anhydrase. To catalyse this reaction, carbonic anhydrase needs a cofactor that attaches to its active site as a prosthetic group. What is ...
