Studied by 4 people
Prosthetic groups
________ are atoms or non- amino acid molecules that are permanently attached to proteins.
Coenzymes
________ are organic molecules that reversibly interact with enzymes.
Active site binding
________ helps substrates to collide in a precise orientation so that particular bonds can break and new bonds can form to generate products.
Adenosine triphosphate
________ (ATP) is a ribonucleotide used for RNA synthesis, but it is more commonly known for its ability to make things happen in cells.
Cofactors
________ are inorganic ions, such as the metal ions Zn2+ (zinc), Mg2+ (magnesium), and Fe2+ (iron), that reversibly interact with enzymes.
phosphorylation
The addition of a phosphate group to a molecule is called ________.
Reduction
________ Is Gain of electrons.
transition state
The ________ is the intermediate point between breaking old bonds and forming new ones.
regulatory molecule
The ________ is similar in size and shape to the enzymes natural substrate and inhibits catalysis by binding to the enzymes active site which is a tactic called competitive inhibition.
Oxidation
________ Is Loss of electrons.
Enzymes
________ are catalysts- they bring substrates together in a precise orientation that makes reactions more likely to occur.
Gibbs
To determine whether a chemical reaction is spontaneous, its necessary to assess the amount of energy in the reaction available to do work- what chemists call ________ free energy.
Redox reactions
________ represent the energetic coupling of two half reactions, one exergonic and one endergonic.
chemical reaction
When reactants undergo a(n) ________ by binding to an enzyme, they are referred to as substrates.
higher potential energy
If heat is taken up during the reaction, generating products that have ________ than the reactants, the reaction is endothermic and change in H is positive.
regulatory molecule
The ________ binds at a location other than the active site and changes the shape of the enzyme.
First law of thermodynamics
the first law is that energy cannot be created or destroyed, it can only be transferred and transformed
Kinetic energy
Energy of motion
Potential energy
Energy that is stored in position or configuration
