Bio 191 Exam (Depaul 2024) 2025
Questions and Answers 100% Pass
What are the functional groups (hint: there are 7 you need to know) - ✔✔-Hydroxyl
-Carboxyl
-Carbonyl
-Amino
-Sulfhydryl
-Phosphate
-Methyl
What is ATP? What are the components? What are some traits? - ✔✔Adenosine
Triphosphate
An adonine has three phosphate groups attached to it
Stores the potential to react with water
Rxn releases energy that the cell can use
How many bonds can carbon make? - ✔✔4
What type of bond does carbon form? Why? - ✔✔Covalent because they e- are shared
What are carbons 3 most frequent partners? - ✔✔Hydrogen, Oxygen, Nitrogen
Hydrocarbons consist of what two elements? - ✔✔Hydrogens and Carbons

, True or False: many organic molecules have hydrocarbon components. - ✔✔True
True or False: hydrocarbons undergo reactions that release a large amount of energy. -
✔✔True
_______ are compounds with the same molecular formula but different structures and
properties. - ✔✔Isomers
____________________ have different covalent arrangements of their atoms. -
✔✔Structural Isomer
_______________________ have the same covalent bonds but differ in spatial
arrangements. - ✔✔Cis-Trans Isomer
__________________ are isomers that are mirror images of each other. - ✔✔Enantiomers
saturated chains are - ✔✔all possible bonds with H (no double)
unsaturated chains are - ✔✔not all carbon chains are bonded with hydrogen (double
bonds)
What are the 4 main biological molecules? - ✔✔Carbohydrates, Lipids, Proteins, Nucleic
Acids
True or false: Monomers are the smaller units that then come together to make a
polymer - ✔✔True
What is hydrolysis? Explain how it is different from dehydration synthesis. (hint: use
the word lyse) - ✔✔Hydrolysis is the breakdown of a polymer. Water is added to
separate/ lyse the bonds between the molecules in the chain. In dehydration synthesis,
water is a product of the reaction. It is formed when two bonds are formed (bonds
between to OH- groups) and an oxygen is also left behind.
Explain Dehydration synthesis in a few words. - ✔✔Water is removed where bond is
formed (hence dehydration)
