Biology 105 chapter 3
with 100% correct
answers (graded A+)
a backbone of 5 or 6 carbon atoms - answer what do common
monosaccharides have?
A central carbon atom (C)
An amine group (—NH2)
A hydrogen group (—H)
A carboxyl group (—COOH, the acid)
An "R group", or functional group, that defines the amino acid - answer what
is the generalized structure of an amino acid?
All three are a chain of glucose monomers but each has different chemical
properties due to different patterns of covalent bonds that link glucose
monomers - answer what are the similarities and differences in those
common polysaccharides?
amine group; carboxyl group - answer Each peptide bond joins the _______
______ of one amino acid and the _______ _______of another in a protein
amino acids - answer are small organic compounds that are the subunits of
proteins
by structure - answer how are proteins functions determined?
, carbohydrates - answer are the most plentiful biological molecules and are
used by cells for energy and as structural materials; is an organic compound
that consists of carbon, hydrogen, and oxygen in a 1:2:1 ratio
carbohydrates, lipids, proteins, and nucleic acids - answer what are the 4
things that make up the molecules of life?
carboxyl group - answer
cellulose - answer the main structural component of plants. chains of glucose
monomers stretched side by side and stabilized into bundles by hydrogen
bonds. A tough and insoluble fiber
cellulose, starch, glycogen, and chiten - answer what are common
polysaccharides?
changes in pH, temperature, and ion concentration - answer why might a
protein denature?
chitin - answer is a durable, translucent, and flexible structural material in
animals and fungi. similar to cellulose, having long, unbranching chains of
nitrogen-containing monomers linked by hydrogen bonds.
cholesterol - answer the most common steroid in animal tissue that cells
remodel to produce many other steroids with an assortment of functions
condensation (dehydration synthesis) - answer a chemical reaction in which
an enzyme builds a large molecule (polymer) from smaller subunits
(monomers). covalent bond formed between 2 molecules.
condensation reactions - answer build polymers
