Introduction to Metabolism, Mitochondria & Chloroplasts


 explain the concepts of free energy and entropy
Free energy: the energy that is available to do work
(not all forms of energy can be converted into biologically relevant
work)


Entropy: disorder of a system
“disorder”: the number of states that a system can take on




 describe the role of ATP in coupling processes that release
energy to those that require energy
Exergonic reaction: energy is released
Endergonic reaction: energy is
required


ATP (Adenosine triphosphate) is used as an energy currency
- energy is stored in the last phosphate group.

- Hydrolysis of ATP:
