Anatomy & Physiology Dr. Benyo: MWF 1:00 – 1:50 EXAM 1: Study Guide Chapters 1-4 EXAM 1: Friday September 23, 2016 Answers are at the end of the review but it is in your best interest to do the review first and take it like a test then see what you missed and what you need to study. Chapter 2 Review Questions Part 1 Multiple Choice: Circle the best answer 1) The simplest form of matter that can’t be broken down by chemical means is known as what? a) Neutrons b) Element c) Nucleus d) Protons e) None of the above 2) In-class Dr. Benyo went over the major elements, which are those major elements? a) Na, Cl, K b) I, F, 10 others c) O, H, C, N, Ca, P d) All of the above 3) Particles that have no charge and have a mass of 1 AMU is known as what? a) Electrons b) Protons c) Trace elements d) Neutrons 4) Which are classified as trace elements? a) O, H, C b) I, F, and 10 others c) Na, Cl, K, Mg d) None of the above 5) An element is composed of what? a) Neutrons b) Protons c) Atoms d) All atoms 6) The proton is made up of what type of particle? a) Negative b) Positive c) No charge d) None of the above 7) The electron is made up of what type of particle? a) Positive charge b) No charge c) Negative charge d) All the above 8) The nucleus is made up of two components. Which two are the correct components that make up the nucleus? a) Protons and Neutrons b) Protons and Electrons, c) Electrons and Neutrons d) None of the above 9) What is the outer energy levels made of? a) Protons b) Neutrons c) Electrons d) None of the above 10) Atoms are identified by which term below? a) Atomic Mass b) Radioisotopes c) Atomic Number d) None of the above 11) If you are not given the Atomic Mass, how do you calculate it? a) Neutrons + Protons b) Protons + Electrons c) Electrons d) Neutrons 12) When an atom has a different atomic mass, this results in different amount of neutrons. What is the term called for this? a) Nonpolar b) Isotopes c) Cation d) Anion 13) How many electrons can occupy the first energy level (electron shell)? a) 3 b) 4 c) 2 d) 8 14) How many electrons occupy the second and third energy levels (electron shell)? a) 2 b) 4 c) 12 d) 8 15) When two or more atoms combine together, it forms what? a) Compound b) Atom c) Element d) Molecule Part 2 True and False: If the statement is true, write a T by the statement. If the statement is false, write a F and correct the statement to make it true. 1) When a nucleus is unstable it is called a radioisotope. 2) Covalent bonds are the most common bond in the body and the weakest. 3) If electron pairs are shared equally it is called a Non -Polar Covalent bond. 4) If electrons are attracted to one nucleus of an atom more than the other, it is not called a Polar Covalent Bond. 5) An ionic bond is when atoms either accept or get rid of electrons to another atom to reach complete outer energy level. 6) A water molecule is non -polar because electrons are not shared between O and H atoms equally. 7) A cation is when an atom loses an electron in which the atom becomes positive. 8) An anion is negative because it gains an electron. 9) Molecules that are formed by an ionic bond cannot easily pull apart (dissociate) when placed in water. 10) In a hydrogen bond, molecules have a weak attraction to each other. Part 3 Fill in the blank: A word bank is provided for you and write the correct term in the blank spot. Dissolve H+ Accept Buffer Cling 10x pH 7.35 Blood Acidosis 1) Solvency is the ability to ______________________ other chemicals. 2) Adhesion is the tendency of molecules to _____________ to each other. 3) In a base, molecules ____________ H+ ions. 4) In an acid, molecules release _______ ion in water solution. 5) A compound that releases or combines with H+ ions to stabilize the pH of a solution pH scale from 0 to 14 is known as _____________. 6) The blood pH level is ____________ to pH of 7.45. 7) If the blood pH becomes less than the range from question 6, it is known as _______________________. 8) Each level of pH scale differs by _______ concentration H+. Part 4 Define the following terms: 1) Macromolecules – 2) Chemical Reactivity - 3) DNA – 4) Nucleic Acids – 5) Enzymes – 6) Primary Structure – 7) Secondary structure – 8) Tertiary structure – 9) Quaternary structure – 10) Functions of Proteins – Part 5 Match the terms to the definition that correctly describes the term . Some numbers may be use more than once for multiple terms: Anabolism 1. Water is lost from the molecule then joins together Synthesis 2. Breakdown of large molecules into small subunits Catabolism 3. Joining of small molecules to form larger ones Hydrolysis 4. Organic molecules Nucleotide 5. Breaking something apart into separate subunits in which water is being added Carbohydrates 6.

Sucrose, Lactose, and Glycogen c. Starch, Lactose, and Cellulose d. None of the above 4) Which definition below is the definition for a conjugated carbohydrate? a. Multiple linked chains b. Covalently linked to proteins or lipids c. Complex, structural plant d. None of the above 5) ATP is considered what for a cell? a. Proteins b. Fats c. Energy Molecule d. Steroids 6) What makes up DNA (DeoxyriboNucleic Acid)? a. Double strands of Nucleic Acids b. PO 4 ribose + Nitrogenous Base c. 2 strands interact by hydrogen bonds d.

Glyceride Chapter 2 Review Questions Answer Key Multiple Choice: 1.) b 6.) b 11.) a 2.) c 7.) c 12.) b 3.) d 8.) a 13.) c 4.) b 9.) c 14.) d 5.) c 10.) c 15.) d True and False: 1) T 2) F, are the strongest bond 3) T 4) F, it is a Polar Covalent Bond 5) F, Ionic bonds do accept electrons but they also donate not get rid of the electrons 6) F, water is Polar because electrons are shared b/w O and H atoms unequally 7) T 8) T 9) F, molecules formed by Ionic Bond can easily pull apart when placed in water 10) T Fill in the blank: 1) Dissolve 2) Cling 3) Accept 4) H+ 5) Buffer 6) pH 7.35 7) Blood Acidosis 8) 10x Define the following terms: Definitions listed in notes. Matching the terms: Anabolism - #3 Synthesis - #1 Catabolism - #2 Hydrolysis - #5 Nucleotide - #6 Carbohydrates - #4 Lipids - #4 Proteins - #4 Nucleic Acids - #4 Multiple Choice: 1) b 2) b 3) a 4) b 5) c 6) d 7) b All these answers are mentioned in the notes I posted. So if you don’t have those notes, they’re very detailed and will help you for the first exam. This review is very extensive based on the material that was covered in just Chapter 2 alone. If you haven’t already, I posted Chapter 1 Review Questions as the first part of this Exam study guide. If you have any questions please feel free to contact me at my student email firstname.lastname@example.org and I will respond back as soon as I can. Thank you!
