ETS & Oxidative Phosphorylation

Redox Energy Calculation:

 

Consider the relative reduction pattern of the ETS in the presence of NADH (highly reduced) oxygen (highly oxidized) and low [ADP].

What would a plot of reduction vs. ETS components (e.g. NADH, FADH2, CoQH2, cyt C, etc.) look like? KEY

Calculations of P/O ratios

Calculate the P/O ratio (ATPs produced for each oxygen atom consumed) for the aerobic catabolism of glucose in mammalian fast twitch muscle. Show all work in a table such as we have used in class. KEY

Do this calculation again for glucose in insect flight muscle. KEY

Fatty Acid Oxidation

Calculate the P/O ratio for the aerobic catabolism of stearate (C=18). Show all work in a table such as we have used in class. KEY
