What is the first law of thermodynamics?
Entropy increases in the universe as energy is transferred
Spontaneous reactions occur based on the speed of a reaction
Energy cannot be created or destroyed
Biological disorder and order are dependent on amino acid chains
Which of the following graphs indicate a positive indication of delta G?
0%

What type of molecule is this? What specific molecule provides energy? Which bond is most like to break?
What is the correct formula for Gibbs' Free energy?
ΔG= G initial state + G final state
ΔG= G final state - G initial state
ΔG= G initial state - G final state
ΔG= G final state + G initial state
Reactions that have a lower activation energy will result in free energy change.
ΔG= G initial state + G final state
ΔG= G final state - G initial state
ΔG= G initial state - G final state
ΔG= G final state + G initial state
Most cells cannot harness heat to perform work because...
Heat is not a form of energy
Cells do not have much heat; they are relatively cool
Temperature is usually uniform throughout a cell
Heat can never be used to do work
Heat must remain constant during work
A noncompetitive inhibitor binds to an enzyme
The action will alter the enzyme shape causing it to be less effective
The action will cause competitive inhibition
The substrate will not be able to bind with the active site
The co enzyme will not function properly
Energy of activation is equivalent to the difficulty of breaking the bonds.
The action will alter the enzyme shape causing it to be less effective
The action will cause competitive inhibition
The substrate will not be able to bind with the active site
The co enzyme will not function properly
Cooperativity allows
More substrates to bind to an active site
Less energy to be used
Substrates to bind faster
Allosteric enzyme to change shape
