Products of cellular respiration:
CO2, H2O, ATP
O2, glucose, ATP
CO2, H2O, ATP, Heat
ADP, H2O, Heat
Goal of cellular respiration:
covert kinetic energy in food to kinetic energy stored in ATP
covert chem energy in food to chem energy stored in ATP
covert mechanical energy in food to chem energy stored in ATP
covert chem energy in food to kinetic energy stored in ATP
If there is no available oxygen, what do your cells do after glycolysis?
catabolism
die
krebs cycle
fermentation
Are pyruvic acid and pyruvate interchangeable in glycolysis?
Most of the time
Yes
No
Sometimes
The Citric Acid Cycle has its products...
exit as excess waste
fuel a new cycle
replenish the original substrate
replenish a different substrate
Fill in the appropriate metabolic process based on its location in the mitochondria
Glycolysis
Citric Acid Cycle/Krebs
Electron Transport Chain
Cellular respiration requires (a) & (b)
Cellular respiration includes what reactions?
Aerobic rxns
Anaerobic & Aerobic rxns
Anaerobic rxns
Only glycolysis is aerobic
Glycolysis is a series of (a) rxns that breaks down (b) carbon into (c) pyruvate acid (3 carbon) molecules.
Match the following
1st phase of glycolysis
Glucose Phosphorylation
2nd phase of glycolysis
Splitting of 6 carbon into 2 molecules
3rd phase of glycolysis
Production of NADH, ATP, 2 pyruvic acid
O2 acts as the ___ in aerobic reactions because it allows NADH and H+ to deilver electrons to the ETC.
neutron acceptor
first proton acceptor
electron sender
final electron acceptor
What results when NADH and H+ deliver H+/electrons back to pyruvate-no O2?
Decreased ATP than aerobic
Lactic acid buildup inhibits glycolysis
Net gain of 2 ATP per glucose molecule broken
Net gain of up to 36 ATP per glucose molecule broken
Pyruvic acid is used to produce (a) in aerobic rxns.
Synthesis of Acetyle Coenzyme A
Citric Acid Cycle
ETC
Glycolysis
Fermentation
End products of aerobic rxns:
Up to 2 ATP per glucose molecule
CO2
H2O
Up to 36 ATP per glucose molecule
For each citric acid molecule 1 (a) is produced, 8 (b) are transferred to NAD+ & FAD, and 2 (c) are produced.
(a) & (b) carry O2 and high energy electrons to the ETC.
The ETC is a series of __ or electron carriers in the mitochondria's inner membrane.
molecules
atoms
enzyme complexes
fat complexes
ETC: Energy from electrons is transferred to the (a) that then uses energy to catalyze (b) of ADP -->ATP. O2 is then the final electron carrier to result in the formation of (c) .
