How do the mitochondria in brown fat offset ATP production in favor of heat generation? O They prevent the formation of the proton gradient across the inner membrane. O They quickly pump protons across the inner membrane. O They prevent the formation of the proton gradient across the outer membrane. O They supply more oxygen to serve as a terminal electron acceptor during respiration.

About 30 ATP are produced per glucose molecule oxidized. What would happen to the yield of ATP per glucose if the mitochondrial inner membrane suddenly became leakier?  Why? What protein makes the inner-membrane leakier?

Throughout the electron transport chain many reactions occur. What happens to NADH eventually? NADH is reduced NADH is not used in ETC. ONADH remains unchanged in ETC but is used later. ONADH is oxidized

We covered in lecture that the complete oxidation of glucose (all the way to CO2 and H₂O and "cashed in" via the ETC) could yield up to 32 ATP. However, a molecule does not always need to start at glucose to be broken down. Answer the following questions if you started with a single molecule of 1,3- bisphosphoglycerate. 2 3 Starting at a single molecule of 1,3-bisphosphoglycerate, how much ATP would be made in glycolysis alone? How much FADH₂ would be produced in the PDC reaction? Dal How much total NADH would be produced from the complete oxidation of 1,3- bPG (re-read the prompt if necessary to consider what complete oxidation means)? Using the appropriate ATP equivalents for NADH and FADH2, how much total ATP (and/or ATP equivalents) would the complete oxidation of 1,3- bisphosphoglycerate yield? --DO
