Glycolysis
What is being oxidized in glycolysis
Glucose
What is the main input for Pyruvate breakdown
Pyruvate ( if they said another input give em the points)
What molecule do we “put into the CAC”?
AcetylCoA
What is the final electron acceptor?
Oxygen
Where does glycolysis occur?
Glycolysis occurs in the cytosol
What molecule is required in order for Pyruvate to breakdown into AcetylCoA?
Coenzyme A
Why is the CAC considered a cycle?
Because it produces the same molecule to start the cycle again
What type of gradient is produced by thr ETC?
A proton (H+) gradient
What phase in glycolysis causes us to only produce Net ATP?
The energy investment phase
What process occurs when there is an absence of oxygen? What product does it make in humans? What does it make in yeast?
Fermentation occurs. Lactic acid. Ethanol
What two types of negative feedback does the CAC have?
Allosteric and Competitive
What product is primarily produced by oxidative phosphorylation and not the etc?
ATP
What is glycolysis regulated by? What happens when what it's regulated is high? What happens when what is regulated is low?
The concentration of ATP, it will down regulate, it will up regulate
What is the negative and positive feedback for Pyruvate breakdown?
Positive: High NAD+ and coenzyme A
negative: High AcetylCoA and NADH
What molecule does AcetylCoA ultimately become in order to continue the CAC
Oxaloacetate
What is the purpose of ATP synthase and how does it work?
It is used to create ATP. It does this by creating a electrochemical gradient produced by the H ions and funneling them into it’s F0 subunit to cycle 4 H ions to create 1 ATP
What is the overall reaction equation for glycolysis?
Glucose + 2 ATP + 2ADP + 2NAD+ -> 2 pyruvate + 2NADH + 2 H+ + 4ATP
What is the overall reaction for pyruvate breakdown?
2 Pyruvate + 2 NAD+ + 2 coenzyme A -> 2AcetylCoA + 2CO2 + 2NADH + 2H+
What is the overall equation for the CAC?
2 acetylCoA + 2 FAD+ + 6NAD+ -> 4CO2 + 6NADH + 2FADH2 + 2 ATP + 6H+
What is the overall equation for the ETC?
