Cellular Respiration I
What are the steps of cellular respiration?
Glycolysis, Krebs cycle, and Electron Transport
What are the two reactants of cellular respiration?
Glucose and oxygen
What are the three products of cellular respiration?
Water, ATP, and carbon dioxide
About how many ATP molecules are produced per glucose if cellular respiration is successfully carried out?
About 32-36
What type of fermentation does the human body go through?
Lactic acid fermentation
Which step produces the MOST amount of ATP?
Oxidative Phosphorylation
What is the molecule called that glucose splits into after harvesting the energy from it?
Pyruvate
Which process of cellular respiration is anaerobic?
Glycolysis
Where does the Citric Acid Cycle occur?
In the mitochondrial matrix
The final electron/H+ acceptor at the end of the Electron Transport Chain
Oxygen (O2)
In what part of the cell does glycolysis occur?
Cytosol
These steps in the cellular respiration process require oxygen
Citric Acid Cycle and Oxidative Phosphorylation
This is the 2-carbon chain compound that is formed just before entering the Citric Acid cycle
Acetyl-CoA
The number of "turns" does the Citric Acid cycle do for each molecule of glucose
2
What is the main product of alcoholic fermentation?
Ethanol (alcohol)
The net number of ATP molecules produced in glycolysis
2
These are used throughout cellular respiration to speed up reactions by lowering activation energy.
Enzymes
What are the names of the two electron carriers in cellular respiration?
NADH and FADH2?
What compounds does fermentation makes?
Lactic acid and alcohol
This molecule is created when oxygen (O2), H+ ions, and electrons combine at the end of the Electron Transport Chain
Water (H2O)
The total amount of ATP produced in glycolysis.
4
H+ ions gets pumped from low concentration to high concentration in which step of cellular respiration
Electron Transport Chain
What kind of ions pass through ATP synthase to make ATP?
H+ (Hydrogen)
What organelle does cellular respiration take place in?
Mitochondria
What is the main enzyme at the end of Oxidative Phosphorylation? And what is its purpose?
ATP synthase
