The graph shows how the free‑energy change for the hydrolysis of ATP varies as a function of Mg2+ concentration. Note that pMg = –log[Mg2+]. What does the graph tell you about the relationship between Mg2+ concentration and ATP hydrolysis? What is the mechanism that explains the relationship between Mg2+ concentration and ATP hydrolysis?

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. You will have to look up one more value online to answer this question, but you do not need to know anything about lipid metabolism. A) approx. 16 to 17 g of fat B) approx. 65 to 66 g of fat C) approx 22 to 23 kg of fat D) approx. 267 to 268 g of fat E) approx. 5 to 6 kg of fat
