BSC 108 -test 1 - YATES UA-Questions
with Complete Answers.
Base - Answer a substance that decreases the hydrogen ion concentration in a solution. PH
greater than 7.
base examples - Answer sodium and hydroxide
acid examp - Answer hydrochloric acid and stomach acid
hydrolysis reaction - Answer adds the equivalent of a water molecule to break apart
macromolecules, examp. breakdown of lactose into its monomers by the enzyme lactose
dehydration reaction - Answer removes equivalent of a water molecule to link molecular units,
builds macromolecules from smaller subunits, dehydration is the opposite of hydrolysis
the 4 macromolecules of life - Answer 1. carbohydrates
2.lipids
3.proteins
4. nucleic acids
carbohydrates - Answer includes sugars and polymers of sugars, small sugar molecules
dissolved into energy drinks
lipids - Answer do not mix with water, oil
proteins - Answer polymer of amino acid monomers
nucleic acids - Answer store info and provide the insturctions for building proteins, DNA and
RNA are nucleic acids
cells make macromolecules by - Answer linking monomers and polymers
what is high frutose corn syrup - Answer a disaccharide that is converting natural glucose in
corn syrup into fructose
, why are trans fats unhealthy - Answer a double bond is created unnaturally
organic molecule - Answer the study of carbon based molecules
difference bw simple and complex molecules - Answer simple carbs=monosaccharids that cant
be broken down
complex= polysaccharids that are long chains of monosaccharids
monosaccharides - Answer glucose and fructose, fruit and honey
disaccarides - Answer lactose and maltose , table sugar and hyfrutose corn syrup
glycogen - Answer how animals store excess sugar in form of polysaccharide
starch - Answer how plants store energy
diff bw sat. and unsat lipids - Answer unsat= has fewer than max number of hydrogens at a
double bond, bended shape
sat=contain max hydrogens, have straight shape
phospholipids - Answer similar to neutral fats, composite molecules, part associates with
water half doesnt
peptide bond - Answer bond bw adjacent amino acids
what effects protein folding - Answer unfavorable temp and PH changes, high fever
Roles of proteins - Answer instrumental in almost all cell functions, when a cell forms an
polypeptide the chain folds for the protein which allows certain functions to be acheivable
James Watson - Answer won nobel prize for describing the double helix
diff bw DNA and RNA - Answer DNA- double helix and uses thyamine
RNA- single stranded, uses sugar ribose and uracil
DNA bases - Answer adenine, cytosine, guanine, thymine
