Biochem+Exam+Review

Multiple choice

 * Ionic vs covalent bond
 * What actually reacts when a chemical reaction occurs
 * 6 elements making up protein
 * the 4 organic compounds (categories) and their monomers
 * pH scale
 * adhesion and cohesion allows what things to happen
 * saturated vs unsaturated fat: differences
 * function of enzymes
 * ways to affect how enzyme works
 * enzymes in relationship to digestion
 * examples of use of extracellular digestion
 * Van der waal forces

Matching

 * Organic groups w/ common molecules (examples) &/or monomers

True/false

 * Cold vs warm water ability to hold oxygen
 * Ulcers and heartburn cause
 * Saturated vs unsaturated fats in regards to source and /or health effects
 * Use of steroids effects
 * HDL’s vs LDL’s- which is best and why
 * What do amylase and maltase and galactase break down

Short answer/ Identification

 * Given an elements and its atomic number and mass, diagram where the electrons are in each shell and how many protons and neutrons are in the nucleus
 * know the equation: acid + base ---> salt + water
 * Water properties explain what mean and importance to life
 * Blood buffers do what?
 * Diagram a condensation or hydrolysis reaction
 * Recognize a peptide bond, hydrophobic/hydrophilic parts of lipids
 * Recognize organic molecules and their monomers by picture and carboxyl/amino groups
 * Why we die from high temperatures
 * Lock and key of enzyme/substrate complex- what does that mean
 * Know the enzyme graphs

Lab applications
(note: in all the following, you will be asked to justify your reasoning/ explain the logic behind your answers and use given data to support it) understand the idea that the pH can effect the enzyme function and that in the stomach, acid (HCl) is NOT there to digest the food- it is the create the right pH for enzymes to work
 * From discussions and the lab about enzymes, what affects them and their role in digestion-
