Cellular Respiration
Term | Definition |
---|---|
Four steps of cellular respiration- | glycolysis, pyruvate oxidation, citric acid cycle, oxidative phosphorylation |
Products of glycolysis- | 2 ATP, 2 NADH, 2 H2O, 2 pyruvates |
Energy investment phase of glycolysis- | the investment of 2 ATP to start the breakdown of glucose |
Energy payoff phase of glycolysis- | the production of 4 ATP and 2 NADH, resulting in 2 pyruvates and 2 water molecules |
Where does glycolysis take place?- | cytosol of mitochondria |
Pyruvate oxidation- | the pairing of a CoA enzyme to each pyruvate, resulting in Acetyl CoA and 2 NADH |
What is lost in pyruvate oxidation? | 2 CO2 |
Where does pyruvate oxidation take place? | mitochondria |
What are the products of the Citric acid cycle? | 6 NADH, 2 FADH2, 2 ATP |
For one glucose molecule to start, how many times does the citric acid run? | Twice |
What is the first molecule in the citric acid cycle? | citrate |
What is the last molecule produced in the citric acid cycle? | Oxaloacetate |
What is lost in the citric acid cycle? | CO2 |
Where does oxidative phosphorylation take place? | Mitochondrial membrane |
What is donated to oxidative phosphorylation by the citric acid cycle? | FADH2 and NADH |
How many electrons travel down the electron transport chain? | 2 electrons |
What happens to protons during oxidative phosphorylation? | energy released pumps protons across the electron transport chain to form a proton motive force in the intermembrane space |
What is the proton concentration like in the matrix of the mitochondria? | there is a low proton concentration |
What is the final acceptor of electrons on the electron transport chain? | oxygen |
What function of the ATP Synthase? | proton motive force is pumped through, creating about 26-28 ATP |
What is the making of ATP driven by? | the transfer of electrons from food to oxygen |
What is a product of the fourth major protein on the transport chain? | Water |
How do electrons move down the electron transport chain? | a series of redox reactions |
Chemiosmosis- | coupling of proton motive force with the creation of ATP |
1 NADH=? | 2 ½ ATP |
1 FADH2=? | 1 ½ ATP |
How many ATP are made in cellular respiration? | You didn't have an answer but I think its 38 |
What is the formula for cellular respiration? | C6H12O6 + 6O2 Right Arrow 6CO2 + 6H2O + Energy |
