BSC 1010C Chapter 3 Questions With Complete Solutions
a protein's overall folded shape Correct Answers is essential to
its function.
a protein's primary structure Correct Answers or sequence of
amino acids, is responsible for most of its chemical properties.
active conformation Correct Answers Many proteins must first
bind to other molecules or ions before they can adopt this
active site Correct Answers The location in an enzyme
molecule where substrates (reactant molecules) bind and react.
alpha-helix (α-helix) Correct Answers A secondary structure in
proteins is formed when the polypeptide backbone coils into a
spiral shape stabilized by hydrogen bonding.
amino acid Correct Answers A small organic molecule with a
central carbon atom bonded to an amino group (-NH3), a
carboxyl group (-COOH), a hydrogen atom, and a side chain.
When these are linked together to form proteins, they are
referred to as residues.
amino acids Correct Answers have a central carbon bonded to
an amino group, a hydrogen atom, a carboxyl group, and an R-
group.
an amino group and a carboxyl group Correct Answers What
two functional groups are bound to the central carbon of every
free amino acid monomer?
, beta-pleated sheet (β-pleated sheet) Correct Answers A
secondary structure in proteins formed when the polypeptide
backbone folds into a sheetlike shape stabilized by hydrogen
bonding.
catalysis Correct Answers Acceleration of the rate of a chemical
reaction due to a decrease in the free energy of the transition
state, called the activation energy.
complete protein Correct Answers In many cases, a ________
_______consists of several different polypeptides, bonded
together. The combination of polypeptides represents the
quaternary structure.
condensation reaction Correct Answers A chemical reaction in
which two molecules are joined covalently with the removal of
an -OH from one and an -H from another to form water. In
biology, most of these involve the joining of monomers into
polymers. Also called a dehydration reaction.
dehydration reaction Correct Answers Another name for a
condensation reaction.
denaturation Correct Answers For a macromolecule, loss of its
three-dimensional structure due to breakage of chemical bonds
and interactions, usually caused by exposure to heat, certain
chemicals, or extreme pH conditions.
disulfide bond Correct Answers A covalent bond between two
sulfur atoms, typically in the side chains of certain amino acids
