Biology Accuplacer Exam with Questions
Solved 100% Correct| Verified Answers
hydrolysis - ANSWER chemical reaction where a water molecule breaks one or more bonds -->
substitution, elimination, and solvation
functional groups in carbohydrates - ANSWER hydroxyl and carbonyl (C=O and OH)
monosaccharides --> polysaccharides - ANSWER long chain of monosaccharides linked
by glycosidic bonds becomes a polysaccharide --> starch, glycogen, cellulose, onitin
Process of glucose --> starch, glycogen, cellulose - ANSWER dehydration synthesis b/c a water
molecule is released as each simple sugar molecule of glucose is added to the starch molecule
carbohydrates function in the cell - ANSWER supply energy to all cells but many cells prefer
glucose than fatty acids
lipid - ANSWER non polar molecule composed of carbon, hydrogen, and oxygen; includes fats
and oils
Types of fatty acids - ANSWER saturated: lack double bonds between individual carbon atoms
unsaturated: at least one double bond in fatty acid chain
triglycerides - ANSWER type of fat in blood from extra calories that are needed right
away; provide energy between meals
phosphoglycerides - ANSWER Phospholipids with a glycerol backbone
, amino acids and proteins - ANSWER joined together by peptide bonds (carboxyl group of
one molecule reacts with the amino group of the other molecules :: N,C,H,O)
Peptide bond structure - ANSWER 4 parts - 1: linear, 2: recurring amino acid, 3: way a protein is
formed, 4: subunits held by H+
functions of protein - ANSWER Enzymes: read DNA, Structural: support, allow body to move,
Motility: allow cell migration
nucleic acids examples - ANSWER Ribose (sugar), Nucleotides (basic structure for DNA), ATP,
DNA, RNA, NAD+ and FAD (electron carriers)
metabolism: active and allosteric site - ANSWER act: substrate molecules bind and under
chemical reaction; all: allows activator or inhibitor molecules that bind to enzyme that
regulate activity
Competitive and noncompetitive inhibitors - ANSWER -Passive transport can be blocked
-competitive: attaches to active site so things can't get in
-noncompetitive: binds with a non active site
feedback inhibition - ANSWER end product in a metabolic pathway binds to an enzyme at
the start of the pathway
anabolism and catabolism - ANSWER building up and breaking down (give out energy)
endergonic and exergonic reactions - ANSWER energetically uphill and energetically downhill
Parts of eukaroytic cells and functions - ANSWER nucleus, ribosomes, ER, GA,
lysosomes, vacuoles, mitochondria, cytoskeleton
