- How much fat (in grams) would the body have to burn to produce the daily minimum requirement of 40 kg ATP from ADP and phosphate? Assume that: 1. The fat is metabolized completely to water and carbon dioxide. 2. The energy that is released can be used entirely for ATP production. 3. Complete oxidation of 1 g of fat to water and CO2 releases 9 kcal or 37 kJ. 4. The Delta G for ATP hydrolysis is -30.5 kJ/mol.

- In complex III in the electron transport chain electrons from NADH + H+ are transferred to coenzyme Q. True or Falsearrow_forwardFADH2 is a less powerful reducing agent (electron donor) than NADH. What is the consequence of this in oxidative phosphorylation? FADH, requires more steps than NADH does in electron transport to become oxidized. The electrons from FADH2 enter electron transport at a higher energy level than the electrons from NADH. A molecule of FADH, is only capable of producing 2 molecules of ATP, while a molecule of NADH is capable of producing 3 molecules of ATP. Oxidation of FADH, occurs in the cytoplasm of the cell, while oxidation of NADH occurs in the mitochondria. FADH, can only donate 1 phosphate group to ATP, while NADH can donate 2 phosphate groups to ATP.arrow_forwardExplain how NADH carry electrons by explaining what a hydride is.

What is post-translational processing of proteins and list 3 things that can happen to the proteins synthesized at this stage:arrow_forwardFor the theoretical maximum yield of ATP per glucose molecule oxidized by aerobic respiration, we will assume that for each pair of electrons transferred to the electron transport chain by NADH, 3 ATP will be generated; for each electron pair transferred by FADH2, 2 ATP will be generated. If NADH is produced in the cytoplasm, it will only generate 2 ATP but NADH produced in the mitochondria will release 3 ATP. 1.
