7.3 SG Flashcards
Study guide for 7.3 quiz
What is metabolism?
all chemical reactions of life
What is an anabolic reaction?
making larger molecules out of smaller ones. Examples: dehydration synthesis and endergonic
What is a catabolic reaction?
breaking down larger molecules into smaller ones. Examples hydrolysis and exergonic
What are exergonic reactions?
chemical reactions that release more energy than they require. Examples: hydrolysis exergonic
What are endergonic reactions?
chemical reactions that require more energy than they release. Examples: Anabolic and Dehydration synthesis
What is hydrolysis?
The addition of water breaks a polypeptide bond
What is dehydration synthesis?
The addition of water connects a polypeptide bond.
What is the ATP cycle?
ATP is broken down by the human body into ADP, then through cellular respiration it converts to ATP.
What would a graph of an exergonic reaction look like?
A graph of exergonic would start going up at first then rapidly go down.
What would a graph of an endergonic reaction look like?
A graph of endergonic would start going up rapidly then hit a peak and go down halfway.
What words link with dehydration synthesis?
Anabolic and endergonic reactions
What words link with hydrolysis?
Catabolic and exergonic reactions.
Would an exergonic or an endergonic occur first and why?
An exergonic reaction would start first because endergonic reactions require energy.
