Chapter 6 Flashcards
Kinetic energy
Energy of motion
Potential energy
Stored energy
Thermodynamics
Energy changes, heat is created
Law of conservation
Energy cannot be created or destroyed
Second law of thermodynamics
Energy transactions arenβt always 100% efficient
Free energy
Energy that is able to do work in and system
Endergonic
Reaction that requires input of energy
Exergonic
Reaction that releases excess energy as heat
Activation energy
Extra energy needed to be destabilize existing chemical bonds and initiate chemical bond
ATP
A nucleotide with 3 phosphate groups
Catalysts
Lowers the activation energy needed to initiate a reaction that generate heat
Energy
Capacity to do work
Entropy
Disorder of energy
Spontaneous energy
No energy needed to be added
Catabolism
Breakdown of molecules to transfer energy
Reaction coupling
When reaction with common intermediate is transferred from one side to another
Anabolism
Putting molecules back together to store it
Ribozyme
RNA molecules that have enzymatic properties
Enzyme
Protein molecule
Substrate
Binds to enzyme to create enzyme-substrate complex
Competitive inhibitors
Competes with substrate for same active site
Non competitive inhibitors
Binds to enzymes in other location
Allosteric site
Where most noncompetitive inhibitor bind to
Coenzymes
Organic molecule and unchanged
