UF-BSC2010 Final Exam 1 Questions
and All Correct Answers 2025-2026
Edition.
Unsaturated Fatty Acids - Answer -not saturated with hydrogen bonds
-double bonds/kinks in carbon chain
-liquid at room temp
Fat's major function - Answer storing energy
Phospholipids - Answer -hydrophilic phosphate head and two hydrophobic fatty acid tails
-major components of cell membranes
-form phospholipid bilayer (hydrophilic heads facing extracellular fluid and cytosol, hydrophobic
tails inward)
Anabolic reactions - Answer -construction of complex molecules from simpler ones
-require/absorb energy
-endergonic reactions, free energy of products > reactants
Catabolic reactions - Answer -breakdown of complex molecules to simpler ones
-release energy
-exergonic reactions, free energy of products < reactants
Nucleic Acids made of - Answer -polymers of nucleotide monomers
Nucleic acids function - Answer -store, transmit, and use hereditary information in the form of
genes
Types of nucleic acids (major) - Answer Deoxyribonucleic acid (DNA)
Ribonucleic acid (RNA)
, Nucleotide - Answer -5-carbon sugar
-phosphate group
-nitrogenous base
Nucleoside - Answer -pentose sugar
-nitrogenous base
Phosphodiester bond - Answer -bind nucleotides (condensation rxn)
-hydroxyl group on 3' carbon and phosphate group on 5' carbon of subsequent nucleotide
-forms polynucleotide backbone
Pyrimidines - Answer -nucleotides with one ring structure
-Cytosine
-Thymine/Uracil (in RNA)
Purines - Answer -nucleotides with two ring structures
-Adenine
-Guanine
RNA structure - Answer -Single stranded
-H-bonds can make it fold back on itself
DNA structure - Answer -two strands (double helix)
-H-bonds form between pyrimidines on one strand and purines on the other
-always three rings b/w carbon backbones of each antiparallel strand
Complementary base pairing rules - Answer DNA: Cytosine and Guanine, Thymine and
Adenine
RNA: Cytosine and Guanine, Uracil and Adenine
C-G stronger than A-T
