Metabolism Chemical reactions of life forming bonds between molecules dehydration synthesis synthesis anabolic reactions breaking bonds between molecules hydrolysis digestion catabolic reactions. 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. ch. 12. The protein catalyst. Targets:. Describe the relationship between substrate and an active site in enzymatic reactions. Identify the role of coenzymes and enzymatic reactions. List factors that affect enzymatic activity. Reactions. Most reactions take place in a number of steps which need to be carefully controlled if the cell is to function properly. Enzymes are the most important controllers of cellular reactions. Catalysts. 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. Apoenzymes. , . Holoenzyme. , . Abzymes. , . Synzyme. , . Ribozyme. , . Extremozyme. , Historical Development in . Enzymology. , .
