Question
Chapter 15, Problem 5P
Interpretation Introduction
Interpretation:
The three major stages that take place during the extraction of energy from the food are to be stated.
Concept introduction:
The molecule which helps in the migration of energy produced during the breakdown of food to the other processes of cells is known adenosine triphosphate or ATP. ATP contains adenine as nitrogenous base, a ribose sugar and three phosphate groups.

Modified TRUE or FALSE. Write the word TRUE if the statement is correct. If the statement is false, write the incorrect underlined word/s and indicate the correct word/s to make the statement true.
Catabolic pathways synthesize complex end products from simple substrates and require energy use.
Answer for the number 2 question. Thank you. No need for long explanation.
Fo-F1 ATPase. The energy for ATP synthesis from ADP and Pi is provided by the downhill transport of protons through the rotary FoF1 ATP synthase (lecture 22). The enzyme has 3 a-b and 12 ‘c’ subunits. The mitochondrion maintains Df=180 mV (negative inside), pHin = 8, pHout=7, [Pi] = 3 mM and ADP is present as well.
How much energy is available (from the proton electrochemical gradient) for ATP synthesis under these conditions (in kJ/mol)?
What [ATP]/[ADP] ratio will be established at steady-state under these conditions?
What would be the [ATP]/[ADP] ratio if the enzyme had only 9 ‘c’ subunits? Remember that full revolution of the crank (gamma subunit) produces 3 ATP.
