AP Biology Midterm Review; Questions & Answers 100%
Solved
Dehydration Correct answer-connecting monomers together by the removal of water
Hydrolysis Correct answer-disassembling polymers by the addition of water
Disaccharides Correct answer-glucose + glucose = maltose / glucose + fructose = sucrose
/ glucose + galactose = lactose
Polysaccharides Correct answer-Plants: starch (energy) and cellulose (structure)
Animals: glycogen (energy) and chitin (structure)
*Lipids Correct answer-hydrophobic (very non-polar), consist of long hydrocarbon chains
Fats Correct answer-consist of glycerol and 3 fatty acids, store long term energy,
saturated = no double bond in hydrocarbon tails (no kink), unsaturated = double bond (kink)
Phospholipids Correct answer-consist of phosphate head, glycerol, and 2 fatty acid tails,
tail is hydrophobic, head is hydrophillic
Protein structure and organization Correct answer-composed of an amino group, a
carboxyl group, hydrogen, and an R group, joined by peptide bonds and folded numerous times;
1) Primary (linear sequence) 2) Secondary (helix or pleat) 3) Tertiary 4) Quaternary (globular)

Solved
Protein functions (8) Correct answer-1) enzymes 2) antibodies 3) storage proteins 4)
transport proteins 5) hormones 6) receptor proteins 7) motor proteins 8) structural proteins
*Nucleic Acids Correct answer-DNA (A+T, G+C) carries genetic info, RNA (A+U, G+C)
manufactures proteins
Nuclear Envelope Correct answer-double membrane enclosing the nucleus (where
genetic info is stored) perforated with pores, continuous with ER
Chromatin Correct answer-uncondensed DNA that forms chromosomes during cell
division
Nucleolus Correct answer-nonmembranous structure involved in production of
ribosomes, a nucleus has one or more of these
Rough ER Correct answer-covered in ribosomes, secretes and transports proteins
produced by ribosomes
Smooth ER Correct answer-metabollic processes (synthesis of lipids, metabolism of carbs,
detoxification of drugs and poisons)
Golgi Correct answer-stores, transports, and secretes cell products
