The initial input of energy in chemical reactions is - Activation energy
The second law of thermodynamics states that energy can be - - lost as heat
The energy in a system that is unable to do work— - Potential energy
Non-protein molecules that permanently assist in enzymatic functions are - - Prosthetic
groups
A reaction with a negative ∆G is - - Exergonic
When covalent bonds in organic molecules are broken the energy is not used immediately.
Instead the released energy is stored in — - NAD+
The removal of electrons from an atom or a molecule is reduction. T or F - False
Proteases are enzymes that break the bonds between amino acids. T or F - True
All of the proteins that a given cell can make is the genome. T or F - False
The reactant molecules in enzymatic reactions are the — - Substrate
If inhibition is to be competitive, which of the following must be true? - the substrate
and the inhibitor must be similar
Which of the following is an example of kinetic energy? - A contracting muscle
Increasing the temperature increases the rate of an enzyme-catalyzed reaction. Once a critical
temperature is reached, the reaction stops. Why does this happen? - The polypeptide
chains in the enzyme denature
What is the benefit of mRNA being degraded? - The cell can conserve energy
