Bio Chapter 8

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?

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
