PPt.14: Enzymes & Chemical Reactions Unit 2 Flashcards
1
Q
Universal energy currency of cells
A
Adenosine Triphosphate ATP
2
Q
Delta G is:
A
Free energy
3
Q
Triggers reactions
A
Activation energy
4
Q
Since endergonic reactions are the only ones that can take place spontaneously, how can organisms carry out endergonic reactions, that is, synthesize the complex biological molecules necessary for life?
A
All endergonic reactions must be coupled to the exergonic reactions that release the energy Delta G necessary to drive these reactions
5
Q
Substances that speed up reactions but are unchanged
A
Catalysts
6
Q
Regulation of a protein by binding an effector molecule at a site other than the protein’s active site
A
Allosteric Regulation
7
Q
Some enzymes function only in conjunction with other organic substances
A
Coenzymes
