energy is stored where?
in chemical bonds
what happens when chemical bonds are released?
they are released when the bonds are broken
reactions in which energy is needed to form a bond
reactions in which energy is released from bonds broken
energy possesed by all atoms, ions and molecules
is the constant motion atoms and molecules echibit as a resuly possessing kinetic energy.
- Due to the constant motion molecules collide with on another
Energy of Activation
amount of energy needed for a particular chemical reaction to take place.
moves molecules faster therefore causing more poweful and more frequent collisions reducing the energy of activation and speeding up the Rate of Reaction
as before causes the molecules to move faster, therefore causing more powerful and frequent collisions, also reducing the ENergy of activation and speeding up the rate of reaction
a substance which probides a convoluted surface on which the reactans may meet
Catalyst forms what?
a temporary union with the reactants brining them together (like a singles bar)
Catalyst uses what?
are catalysts. Are composed of proteins made by the cell.
it decreases the energy of activation and accelerates the rate of reaction.
All enzymes are composed of what?
proteins that also hace co - enzymes (vitamins ) and a metal ion
a protein that provides Specificity fue to the unique surface shape of protein.
is a vitamine. Serves to transport a chemical group removed from one molecule to another molecule
CoA (pantothenic acid)
trnsports acetyl CH3COO
serves as a bridge between the enzyme and the substratr
converts a substance into its isomeric form
digests a cellulose
transports a substance into the cell
what affects the activity of an Enzyme?
Mechanism of action of an ENzyme called Lock and Key mechanism
the surface shape of the enzyme is a close mirror image match to the substrate
binfs to the enzymes forming a shoey lived enzymes substrate complex.
