What role do NADH and FADH2 (produced during Glycolysis and Kreb's Cycle) play in cellular respiration
they are energy carriers (hydrogen)that use that energy to produce massive amounts of ATP
They are waste products and are pushed out of the cell
They are necessary for long-term energy storage
They don't play any role in cellular respiration
What happens in the electron transport chain?
NADH and FADH2 drop off hydrogens to form massive amounts of ATP
pyruvic acid is formed from breaking down glucose
CO2 is released and H2O and ATP
glucose is broken down and ATP is formed
What happens to the carbon atoms in glucose during cellular respiration?
They are exhaled as CO2
They disappear
They are broken down and dissolve
They stay in the mitochondria forever

The Electron Transport Chain is a series of chemical reactions in which energy is transferred to form a large amount of what molecule?
glucose
oxygen
pyruvic acid
ATP
The electron transport chain above is used to .
directly create ATP from NAPH and FADH2
use energy from electron carriers to create a H+ gradient
convert pyruvate into NADH and FADH2
store energy from electron carriers into glucose
Why ETC must occur first before chemiosmosis?
to produce H2O
to produce ATP
to create proton-motive force
Describe the process of chemiosmosis in cellular respiration.
Proton gradient is used to generate ATP in the inner mitochondrial membrane through the action of ATP synthase.
Proton gradient is used to oxidize glucose in the inner mitochondrial membrane through the action of ATP synthase.
Chemiosmosis is the process of converting Oxygen into carbon dioxide during cellular respiration.
Chemiosmosis is the process of breaking down ATP to release energy for cellular activities.
How is the proton gradient formed in the electron transport chain?
Pumping of protons across the inner mitochondrial membrane
Diffusion of protons through the inner mitochondrial membrane
Release of protons from the electron carriers
Transport of protons by ATP synthase
H+ moves through ATP Synthase from ___________ concentration in the intermembrane space to ___________ concentration in the mitochondrial matrix.
high; low
low; high
neutral; charged
charged; neutral
What would happen in the electron transport chain if there was no O2?
The cell would dehydrate because no water would be produced.
There would be nowhere for electrons to go after passing through the ETC proteins.
There would be an increase in ATP synthesis.
The cell would produce more electron chain proteins.
True or False: Water is produced as a byproduct at the end of the electron transport chain.
True
False

Fermentation = 2; Aerobic Respiration = 36
Fermentation = 4; Aerobic Respiration = 32
Fermentation = 36; Aerobic Respiration = 2
Fermentation = 2; Aerobic Respiration = 32
