Enzymes

Learn about enzymes! Biology worksheet on function, factors, and graphs. Label parts & understand catalysts.

Activation energy is the energy required for the reaction to happen. In a reaction, an enzyme lowers the activation energy and increases the speed or rate of the reaction without being altered.This makes enzymes known as biological catylsts. Enzymes are which type of macromolecule? lipid nucleic acid protein carbohydrates Functions of Enzymes Watch the video and answer the questions below. Fill in the blanks based on the information in the video. Enzymes increase rateof reaction.Enzymes are not consumed ina reaction.Enzymes can breakmolecules apart, buildor addmolecules and even rearrange molecules.Enzymes loweractivation energy of a reaction. The change in energy remains the samebetween the start and the end of the chemical reaction.Enzymes cause a reaction rate to happen faster Enzyme graph Match the letters of the phrases describing each section of the graph. (The letters are lowercase) f b a e h g Parts of an enzyme Using your knowledge of enzymes and the lock and key model, label the picture below. Use the following word bank:Product, Enzyme, Enzyme, Substrate, Enzyme Complex, Enzyme complex Enzyme Enzyme Substrate Product Enzyme Graphing Match the graphs with their conclusion. Place the capitalized letter in the text box. D C A B Place the correct effect if the factors, pH and temperature change drastically. pH May change the shape of the enzyme or charge properties of the substrate. Temperature Increases rate of reaction but when this gets very high, it can cause denaturing.
