This is one of the most important concepts in biochemistry and is worth taking notes. This video will cover Michaelis Menten vs Lineweaver Burk plots and did a good job in doing so

This video talks about the citric acid cycle i.e. the energy it produces through pyruvate entering the cycle. Some questions to focus on:-
1. What did pyruvate convert into?
2. How many NADH are produced in the citric acid cycle?
3. What is the net ATP produced by NADH and FADH respectively?
4. What does oxaloacetate convert into?

Add Enzymes
If required by your instructor, what is the name of each step process?
Any co-products? If so add them now.
How many NADH do 2 acetyl-coA form?
How many FADH2 do 2 acetyl-coA form?
How many GTP molecules do 2 acetyl-coA form?

This video goes over the steps of glycolysis and how much ATP is produced. Some questions to focus on:-
1. How many NADH are produced?
2. What many FADH are produced?
3. Net ATP produced in Glycolysis?
4. How many pyruvate are produced 1 or 2?

This video goes over the steps of gluconeogenesis and how glycolysis can be reversed. Some questions to focus on:-
1. How many NADH is used?
2. Net ATP used in Gluconeogenesis?
3. Is oxaloacetate produced in this reaction?

Equations
Equations
These are the equations that will be important for the beginning of Chem 150:
pH=-log[H+]/ [H+]= 10^-pH
pOH=-log[OH-]/ [OH-]= 10^-pOH
Kw=[H+][OH-] ; Kw= 1.0 x10 ^-14
pH+pOH=14
It's important you know what they find and what each variable represents.
A few questions to ask yourself:
What is pH? pOH? [H+]? [OH-]?
Are the values you are getting matching with what's to be expected? (i.e. Is a solution that is acidic yielding acidic values (pH 1-6)? Is a solution that is basic yielding basic values (pH 8-14)?
What is the pH of a solution with a concentration of 1.4 x10^-5? What about 7.95x10^-6?
Remember: Is the value you found within the given ranges listed above?
What is the pOH of a solution with a concentration of 3.1 x10^3? What about 5.4 x10^5?
Remember: Is the value you found within the given ranges listed above?
Watch this helpful video to solidify what you just learned above.
