Cellular Respiration Flashcards
What are the steps of cellular respiration?
Glycolysis, Pyruvate Oxidation, Citric Acid Cycle, Electron Transport Chain
What is the formula for cellular respiration?
C6H12O6 + 6 O2 => 6 CO2 + 6 H2O + ATP
Where does glycolysis occur?
Cytosol
Where does Pyruvate Oxidation occur?
Mitochondrial Matrix
Where does the Citric Acid Cycle occur?
Mitochondrial Matrix
Where are the proteins of the electron transport chain?
Inner membrane
What powers ATP synthase?
Proton gradient
What drives the movement of electrons in the ETC?
Redox potential: electrons move from low to high
What stage of cellular respiration doesn’t require oxygen?
Glycolysis
What is the final electron acceptor?
Oxygen —> reduced to water
What is an anabolic reaction?
ADDing molecules
What is a catabolic reaction?
CUTing molecules
What is the delta G of an exergonic reaction?
Negative
What is the delta G of an endergonic reaction?
Positive
Does breaking bonds release or require energy?
Require
