Unit One Review: Biochemistry

Master biochemistry! Review water, macromolecules, and enzymes with our engaging worksheet.

Water Review Structure of Water Match the description of a specific part of the structure of water to its description Oxygen Has a negative charge; One Hydrogen Has a positive charge; Two Polar Water is considered this because the opposite ends have slightly opposite charges Hydrogen Bond Type of bond that holds multiple molecules of water together Put the property of water with its correct description Cohesion - Water's ability to stick to itselfAdhesion - Water's ability to stick to other substancesSpecific Heat- Water requires a lot of energy to raise or lower its temperatureUniversal Solvent- Water is able to dissolve many other substancesExpanding when freezing - The solid form of water is less dense than the liquid and therefore floats. Match the property of water to how it is beneficial for living things Cohesion Allows for capillary action (Ex: Water moving up a straw) Surface Tension Allows small insects to stand on water Expanding when freezing Ice is less dense than water which allows it to serve as an insulator High Heat Capacity Helps organisms maintain homeostasis because it prevents a drastic change in temperature If something has a pH between 0-6 it is considered Acidic Basic If something has a pH of 8-14 it is considered Acidic Basic Biochemistry Match the Macromolecule with its monomer Carbohydrates Monosaccharides Lipids Fatty Acids and Glycerol Nucleic Acids Nucleotides Proteins Amino Acids Match the macromolecule with their primary function Carbohydrate Immediate energy. Lipids Long term energy storage, insulation, and cell membrane Nucleic Acids Stores and transmits genetic information Proteins Builds muscles, makes up antibodies, and acts as a catalyst Fill in the blanks in the following passage in order to gain a better understanding of enzymes. Enzymes are special types of proteins that act as a catalyst in chemical reactions. Catalysts help speed upchemical reactions by lowering the activation energy of a reaction. If an enzyme is not in its ideal pH or temperature,it will change its shape. This is known as denaturing. When an enzyme looses it shape, it looses its function and can no longer speed up chemical reactions. Which letter represents a chemical reaction WITHan enzymepresent? A B A B Only proteins can be large molecules with thousands of subunits.If Enzyme 2 is denatured, the levels of which substance will increase? Lactose Galactose Galactose-1-phosphate Glucose-6-phosphate
