Flashcards in Chapter 3 Deck (34):
Collective term for all biochemical reactions in a living organism
Whenever chemical bonds form/break
Breaks molecules into smaller subunits
Decomposition reaction using water
Assembles large molecules from smaller subunits
Formation of complex molecules by removing water
All decomposition reactions in the body
All synthesis reactions in the body
Parts of the reacting molecules are moved around to create new products
What type of reactions are endergonic?
What type of reactions are exergonic?
Reactants become products at an equal rate of products becoming reactants
Reactants are converted into products
Proteins that catalyze by lowering activation energy
Energy required to start a reaction
Reactants in enzymatic reactions
Region in enzyme with a specific shape
What are the steps in facilitating reactions?
Substrates bind to active site, enzyme substrate complex forms, temporary shape change occurs, product leaves active site
Organic molecules made of adenine and ribose
Where does glycolysis take place?
No oxygen required
Glucose is broken down into 2 pyruvate
How many ATP's are made in glycolysis per glucose?
Pyruvate loses a carbon and binds with coenzyme A
Where does the intermediate stage take place?
Where does the citric acid cycle take place?
How much ATP is formed in the citric acid cycle per glucose?
Sequence of proteins in the inner mitochondrial membrane, use hydrogen ions and electrons from previous steps to create H+ gradient; as hydrogen ions pass through ATP synthase ATP is formed
Electron transport system
How many ATP's are produced per glucose in the ETC per glucose?
How much water is produced in the ETC?
