Degradation Reactions( breakdown )
Metabolism
I am the name given to a substance that
increases the rate of a chemical reaction but
remains unchanged at the end
Competitive Inhibitor
I am the word used to describe what
happens to an enzyme at temperatures
above 40°c
Enzyme
I am the reason why a competitive Inhibitor
slows down the rate of reaction
Enzyme-Substrate Complex
I am the type of enzyme that controls a
chemical process inside cells
Substrate
I am the name given to reactions where
enzymes are used to build up complex
molecules from smaller ones
Protein
I am the word used to describe the fact that
only one enzyme fits one substrate
I am the type of protein that most enzymes
are made from although some may be
conjugated protein
Cyanide and Heavy Metals like Copper,
Mercury and Lead
I am the word used to describe the best set
of conditions that an enzyme works at
Denatured
Synthesis Reactions(Building Up)
I am what affects the degree of inhibition of
an enzyme by a competitive inhibitor
Specific
I am the name given to reactions where
enzymes are used to break down complex
molecules to smaller ones
Catalyst
I am the name given to the complex that
forms when an enzyme locks with its
substrate at the active site
Intracellular Enzyme
I am the name given to a biological catalyst
which speeds up the rate of biochemical
reactions
Neutral pH (pH7)
I am the type of enzyme that controls
reactions outside the cell
I am the enzyme that works best in acidic
conditions (pH2.5) in the stomach to
breakdown protein
Globular Protein
Rate of Reaction Increases
I am what happens to the rate of reaction if
the concentration of substrate is limited
Pepsin
I am what happens to the rate of reaction if
the concentration of enzyme increases
Active Site
I am the name given to the area on an
enzyme whose shape is determined by the
type of bonding between amino acids in the
polypeptide chain that make up the enzyme
Optimum
I am the pH at which most enzymes operate
Extracellular Enzyme
I am the name given to the substance that
an enzyme acts on
Competitive Inhibitor and Non-Competitive
Inhibitor
I am the inhibitor that competes with the
substrate for the active sites on an enzyme
as it has a molecular structure similar to the
substrate
Water and Oxygen
I am the test for oxygen gas
Inhibitor
I am the two types of inhibitor
Non-Competitive Inhibitor
I am four examples of non-competitive
inhibitors
I am the substance that enzymes are made
from
The Rate of Reaction Decreases
I am an enzyme made in living cells to
breakdown hydrogen peroxide
Relights a Glowing Splint
I am the name given to a substance which
decreases the rate of an enzyme-controlled
reaction and may even bring it to a halt
Catalase
I am the two products formed from the
breakdown of hydrogen peroxide
The Active Sites Become Blocked by the
Competitive Inhibitor and the Substrate can
no longer fill these spaces
Concentration of Inhibitor Only
I am the type of inhibitor that combines with
an area away from the active site and
indirectly alters the active site so it no longer
fits the usual substrate
Co-factor
I am the name of an inhibitor that can affect
the action of catalase enzyme on its
substrate hydrogen peroxide
Copper Nitrate
I am the name given to co-factors that
contain vitamins as the main part of their
molecular structure
Concentration of Inhibitor and Substrate
I am the name given to a non-protein
substance like zinc, iron, copper or
magnesium that must be present to activate
an enzyme
Enzyme Activators
I am what affects the degree of inhibition of
an enzyme by a non-competitive inhibitor
I am the name given to a group of chemical
processes that occur in the human body to
keep it alive
I am the name given to substances that
convert an inactive enzyme to an active form
e.g. trypsin converts inactive
chymotrypsinogen to active chymotrypsin to
digest protein in the small intestine
