Flashcards in Bioenergetics Deck (11):
What is bioenergetics?
How cells produce and use energy
Roles of bioenergetics
General manager - thermodynamics
Process engineer - biochemistry - maya olive pathways and networks
Control engineer - enzyme kinetics - regulation and signalling
First law of thermodynamics
Energy can neither be created or destroyed, it is simply conserved
Second law of thermodynamics
Every energy transfer increases the entropy of the universe - an organism loses some of its energy to the environment
What is the free energy of the system?
Is the portion of the system's energy that can perform work
In an exergonic reaction, is energy released or required?
In an endergonic reaction, is energy released or required?
Energy is required
What does ATP stand for?
Where is the chemical energy in ATP stored?
The last phosphate group
What are the two steps of ATP formation?
1) substrate level phosphorylation
2) oxidative phosphorylation
