PPT-3.6: ENZYMES

Enzymes a globular protein that functions as a biological catalyst of chemical reactions digestion respiration They remain unchanged at the end of the process Proteins with long polypeptide chains folded in 3D shapes. Chapter 2: Section 2.5. 1. Objectives. SWBAT explain the effect of a catalyst on activation energy. . SWBAT describe how enzymes regulate chemical reactions. . and maintain homeostasis.. 2. Starter: How can this be possible. 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. Essential idea: Enzymes control the metabolism of the cell.. Above is just a small part of the IUBMB-. Sigma-Nicholson Metabolic Pathways Chart . aims to show all the metabolic pathways found in eukaryote cells. The chart in it's entirety shows how complex the chemicals reactions needed to support life in a single cell unit. This was mentioned earlier in 2.1, but in addition to the complexity now add to that . Warm up. Grab warm up and complete. We will be putting this into your . journal. When you are done with your warm up look over your Vocab 1-1, you have a . quiz today. Biomolecule review. Cellulose, a structural component of the cell wall of plants and some forms of algae, is mainly used to produce paper and cardboard products. Cellulose would be an example of which type of biomolecule. 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. 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. 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 . Enzyme & Substrate. An enzyme is a globular protein which acts as a biological catalyst by speeding up the rate of chemical reactions. . Enzymes are . NOT. changed or consumed by the reactions they catalyze and thus can be reused. . Restriction enzymes. Polymerase enzyme. Strand-displacing polymerases. Helicase enzymes. Discovery and Obtainability:. Most enzymes are proteins discovered in cells.. But . DNAzymes. were . descovered. Enzymes. Back when we discussed proteins, we learned that one critical function of protein was to speed up chemical reactions.. Enzymes. are the proteins that increase the rate of chemical reactions.
