Concept explainers
(a)
Interpretation:
The reaction for conversion of creatine phosphate to creatine has to be written.
Concept Introduction:
1. Nitrogen-containing base
2. Pentose sugar
3. Phosphate group
Examples of nucleosides are GTP and ATP. Nucleotide on hydrolysis releases energy by cleavage of phosphoanhydride bond. The reaction of hydrolysis of ATP is as follows:
(b)
Interpretation:
Whether energy is released or absorbed in formation of creatine by creatine phosphate has to be determined.

- Running a mile in ten minutes burns between 100 and 120 calories for a 150-pound person. For the same run, a 200-pound person needs about 135-155 calories. In grams, how much ATP is required for this workout? ATP has a molecular mass of 507 g/mol. ATP's g-phosphate group hydrolysis has a free energy of -32 kJ/mol. One calorie is equal to 1000 calories, and one calorie is equal to 4.184 kilojoules (kJ). How much glucose do you need to fuel this run, both aerobically and anaerobically? Assume that one glucose molecule yields 30 ATP when processed aerobically. Molality of glucose is 180g/mol.arrow_forwardO2g) 2 CH;OH) +3 O2G) → 2 CO2) + 4 H,O0 + 347 kcal Calculate the amount of heat in kcal & kJ released when 25.4 g of CH,OH, reacts.arrow_forwardYou decide to go on a diet to lose 5 lbs (1 lb = 454 g).

The heat of reaction for the combustion of cyclobutane, C4H8, is 650.3 kcal/mol. What is the heat of combustion for cyclobutane in kcal/gram? kcal/gram How much heat will be given off if molar quantities of cyclobutane react according to the following equation? C4H8 +602 → 4CO2 + 4H₂O kcalarrow_forward
- When CH4(g) reacts with H2O(g) to form H2(g) and CO(g) , 49.2 kcal of energy are absorbed for each mole of CH,(g) that reacts.
