THERMODYNAMICS Flashcards
(35 cards)
It is the study of energy changes and transfer and utilization of energy
Thermodynamics
Other term for bionergetics
Thermodynamics
Free energy is discovered by
Willard gibbs
Other names for free energy
Gibbs energy
Useful energy
Tells you the direction of the reaction
Free energy
Direction of reaction. Free energy
Exergonic
Equilibrium
Endergonic
Will occur spontaneously
No need to add energy
Forward reaction – EXERGONIC
‘G < 0
NEGATIVE
No reaction in the envt
Equilibrium
Non spontaneous
Needs an energy source to start
ENDERGONIC
G > 0
POSITIVE
Energy is not created nor destroyed
It is only transformed to another type
Or transported to other region
Law of conservation of energy
Law: randomness or disorderness of an envt
Entropy
Entropy: Measures heat contents of products and reactants
Enthalpy
Entropy: Heat release
Exothermic
Combination of degradation and synthesis
Break down or build up
Metabolism
Series of chemical reaction
OLIGH
Oxidation-reduction Ligation Isomerization Group transfer Hydrolysis
Series of chemical reactions
Step by step of chemical reactions
SUM of all biochemical rxn, but not at the same time
Metabolic pathway
Metabolic pathway occurs in the
Cell
3 types of reactions in metabolic pathway
Catabolism
Anabolism
Amphibolic
Breaking down large molecules
It provided energy or atp
Catabolism
Use of small molecules to build large ones
Requires energy
Anabolism
Can see both anabolism and catabolism
Amphibolic
Structural basis of high phosphoryl transfer potential
Atp
Above atp
High energy phosphate
Below atp
Low energy phosphate
