Cellular Respiration I
This molecule is the final electron acceptor in the electron transport chain.
Oxygen
is a partial degradation of sugars that occurs without O2
fermentation
consumes organic molecules and O2 and yields ATP
aerobic respiration
What is the formula for Cellular Respiration?
C6H12O6 + 6 O2 --->6 CO2 + 6 H2O + energy
How many stages does harvesting energy from glucose have?
3
Where does NADH pass electrons?
electron transport chain
Does NAD+ accept or donate electrons?
accepts electrons
O2
the fuel (such as glucose)
What the last step to happen for citric acid cycle to begin?
pyruvate must be converted to acetyl CoA
This stage of cellular respiration breaks down glucose into two molecules of pyruvate:
glycolysis
This stage of cellular respiration completes the breakdown of glucose:
citric acid cycle
This stage of cellular respiration has an electron transport chain and chemiosmosis. It also accounts for most of the ATP synthesis
oxidative phosphorylation
Where is the electron transport chain located?
inner mitochondrial membrane
These two electron carriers deliver high‑energy electrons to the electron transport chain.
NADH and FADH₂
What is the name of the protein enzyme that has H+ moving back across the membrane?
ATP Synthase
What are the 2 processes of oxidative phosphorylation?
electron transport chain and chemiosmosis
How many ATP does oxidative phosphorylation make?
30-32 ATP
How many ATP, NADH, and FADH2 does the citric acid cycle produce per glucose molecule?
2 ATP, 6 NADH, and 2 FADH2
What is the net production of ATP, NADH, and Pyruvate in glycolysis?
2 ATP, 2 NADH, and 2 Pyruvate
This is the location where the citric acid cycle takes place.
Mitochondrial Matrix
This term describes the combined effect of the H⁺ gradient and membrane potential that drives ATP synthesis.
The proton motive force
This gas is released during pyruvate oxidation and the citric acid cycle.
CO2
This type of ATP production occurs when an enzyme transfers a phosphate group directly to ADP.
Substrate level phosphorylation
This is the only electron transport chain complex that does not pump protons across the membrane.
