AP BIOLOGY – Ch 9 Exam: Respiration…………Things to Know for the Test







Catabolic pathway
Endergonic/Exergonic
Phosphorylation (how does it affect chemical reactivity?)
Oxidation Reaction, Reduction Reaction, REDOX Reaction
 C6H12O6 + 6O2  6CO2 + 6H2O + energy (ATP)

Electronegativity (releasing energy, atom gaining e- is reduced)

Electrons = energy! (Transported in H atom)

Where each stage of cell resp. takes place

Substrate-level phosphorylation
o Where takes place?
o Which ATP come from this?

Where do e- go at end of E.T.C.? What is produced?

Anaerobic vs. Aerobic (How does this relate to glycolysis?)

KNOW YOUR DIAGRAMS! (See diagram sheet)

Formation of AcetylCoA from pyruvate
o What is happening?
o What is produced?

Electron path of aerobic respiration


Oxidative phosphorylation  ATP synthase
vs.
Substrate-level phosphorylation  Pi comes from substrate

Each NADH transfers a pair of e-

Proton-motive force, Chemiosmosis

NADH = _____ ATP, FADH2 = _____ ATP

What pulls e- down ETC?

How each part of the formula plays a role in cellular resp. (Where do they come from? How are they produced?)

40% of energy from glucose is transferred to ATP – a car is only 25%!


Fermentation (substrate-level phophorylation)
o WHY?
o WHEN?
o WHERE?
o TYPES?
Muscles and fermentation

Evolutionary significance of glycolysis

What other macromolecules are broken down by glycolysis and krebs?
