CHEM 210 Final Exam

Questions and Answers

  • True or False: Nitrogen is called the superglue of the chemical world.: FALSE
  • True or False: Large elements, such as strontium, are common in biomole- cules.: FALSE
  • True or False: The time it takes for a compound to flow through a metabolic pathway is called the payoff phase.: FALSE
  • True or False: Proteins, carbohydrates, and fats all get broken down into acetyl-CoA.: TRUE
  • True or False: A fat is a lipid molecule that is a solid at room temperature.- : TRUE
  • In DNA, guanine always pairs with .: Cytosine
  • Which of the following is the structure of ADP?: 2 DOUBLE O
  • The H+ concentration of a solution is 7.9 x 10- 13 M. What is the pH?: 12.1 [ [H+]=7.9 x 10-13; pH=-log[7.9 x 10-13]= 12.1]
  • Which of the following is the enthalpy change of a reaction?: ”H
  • nti-parallel
  • The following is what type of protein secondary structure?: A beta sheet
  • A globular protein is an example of a protein
  • A lipid is .: A molecule that dissolves in a non-polar solvent
  • Lipids are catabolized by the pathway.: B- oxidation
  • FADH2 provides energy by donating electron and hydrogens to the .: ETC
  • The direct production of ATP occurs as H+ ions flow through
  • The following processes result in either the "Production of ATP" or in the "Consumption of ATP". Put each of the following into the appropriate cate- gory.: 1. Fructose-6-phosphate forms Fructose-1,6-bisphosphate = Consumption of ATP
  • Oxidative phosphorylation = Production of ATP
  • Glucose forms two pyruvates = Production of ATP
  • Pyruvate forms acetyl-CoA = Production of ATP
  • NH4+ is made into urea = Consumption of ATP
  1. In human cells, amino acids are degraded to ammonium NH4+ and carbon skeletons. How is the nitrogen then further processed and excreted from these cells.: 1. Nitrogen is processed separately from carbon and oxygen, in the urea cycle. The urea cycle is a four-step cyclic process that converts NH4+ to urea, which is then excreted from the body.
  • Once the NH4+ is removed, it is acted upon in the mitochondria by an enzyme, carbamoyl phosphate synthetase 1, that synthesizes carbamoyl-phosphate.
  • The carbamoyl phosphate enters the cytosol and continue through the three further steps of the urea cycle producing urea. The urea, containing two atoms of nitrogen, is then excreted.
  1. Describe at least three properties of carbon that permit it to be the basis of life.: 1. Carbon can form stable covalent bonds with a variety of different elements.
  • carbon can form double and triple bonds with other carbon atoms and other elements (N and O).
  • Carbon can form long chains by forming numerous carbon-carbon bonds called polymers.
  • Lastly, carbon can form cyclic structures, which are

fats all get broken down into NADH and FADH2 in energy production.: TRUE

  • True or False: A fat is a lipid molecule that is liquid at room temperature.- : FALSE
  • In RNA, guanine always pairs with : Cytosine
  • In RNA, Adenine pairs with: Uracil
  • In DNA, Adenine pairs with: Thymine
  • Which of the following is the structure of ATP?: 3 DOUBLE O BONDS
  • Which attribute contributes to water's unusual properties?: All of the an- swers are correct
  • Which of the following is the free- energy change of a reaction?: ”G
  • Parallel beta
  • The following is what type of protein secondary structure?: sheet
  • A fibrous protein is an example of a protein.: Conformation
  • In a particular cell, molecule X binds to an enzyme causing it to stop catalyzing reactions. Molecules X is called what?: Inhibitor
  • The following are all example of a lipid's

function in cells except Catalysis

  • cid
  • The following is an example of a biomolecule.: Nucleic A
  • A particular lipid is a solid at room temperature, so it's called a(n).: Fat
  • The primary sequence of proteins is written : 5' to 3'
  • Proteins are catabolized by the pathway: Urea cycle
