Enzymes (not complete) Flashcards
are proteins that help speed up
metabolism, or the chemical reactions in
our bodies.
Enzymes
They build some substances
and break others down.
Enzymes
All living things
have _______.
enzymes
Our bodies naturally produce_______ .
enzymes
are also in manufactured
products and food.
Enzymes
One of the most important roles of
_______ is to aid in digestion.
enzymes
there are enzymes in our_______, _______, ____ and ______.
saliva, pancreas, intestines and
stomach.
They break down fats,
proteins and carbohydrates.
enzymes
Enzymes are essential for?
digestion, liver function and much
more.
Enzymes also help with?
Breathing.
Building muscle.
Nerve function.
Ridding our
bodies of toxins
______ or ______ of a certain enzyme can cause health
problems
Too much, too little
Enzymes in our______
can also help healthcare providers
check for injuries and diseases.
blood
A reactant in a chemical reaction
is called a substrate when acted
upon by an enzyme
Substrate
is the part of an
enzyme to which substrates bind
and where a reaction is
catalyzed
Active site
The active site of an enzyme is
precisely shaped to hold specific
substrates
lock-and-key
model
The active site and substrate don’t fit perfectly together;
instead, they both alter their shape to connect
induced-fit model
a substrate binds to an enzyme (via the
active site) to form an enzyme-substrate complex
Normal Enzyme Reaction
enzyme + substrate =
enzyme-substrate complex
involves a molecule, other than the substrate, binding to the enzymes active site
Competitive innibition
Competitive innibition involves a molecule, other than the substrate, binding to the enzymes___
active site
the molecule (inhibitors) structurally and chemically similar to the substrate hence able to bing to the active site
Competitive Inhibitor
blocks the active site and thus prevents substrate binding
competitive inhibitor
As the Inhibitors is in competition with the substrate. Its effects can be reduced by?
increasing the substrate concentration
enzyme + inhibitor
enzyme- inhibitor complex
involves a molecule binding to a site other than the active site (an allosteric site)
Non-competitive Inhibition
Non competitive Inhibition involves a molecule binding to a site other than the active site __
an allosteric site
Reversible
Competitive Inhibitor
irreversible
Non-competitive inhibitor
at what temperature enzyme will denatured
45 and 50
what best temperature for enzyme
40 and 50
best ph for enzyme
optimum ph
factors affecting enzyme
Concentration of enzyme
Concentration of substrate
Temperature
Hydrogen Ion Concentration (pH)
