Why are high energy phosphate bonds a good means of storing energy?
Homework Answers
High energy phosphate bonds, when they break provide a tremendous amount of release of energy which is used in cellular functions .
This energy comes from:
a) Increase of entropy after bond breakage
2) Solvation stabilisation of broken bonds
3) Electrostatic repulsion of negative charges prior to bond breakage
4) Resonance stabilisation of products formed

A rotating flywheel has been proposed as a means of temporarily storing mechanical energy in an automobile, providing an energy source for the car. The energy that can be stored in this way is limited by the size and weight of the flywheel and by the maximum angular velocity it can attain without flying apart. Suppose a solid cylindrical flywheel of radius 85.0 cm and mass 90.0 kg rotates at a maximum angular velocity of 270 rad/s. Find the maximum...

Very large capacitors have been considered as a means for storing electrical energy. If we constructed a very large parallel-plate capacitor of plate area 1.85m2 using paper (k = 3.7) of thickness 1.5 mm as a dielectric, how much electrical energy would it store at a plate voltage of 1500 V? (e0 = 8.85x10-12 C2/N.m2) A) 0.045 J B) 9.1 J C) 910 J D) 1800 J E) 3600 J

We have seen all term that cells use the hydrolysis of high energy phosphate from ATP to make metabolic reactions thermodynamically favorable. Whereas most enzymes that utilize ATP hydrolyze between the b and g phosphates (yielding ADP + Pi), some enzymes hydrolyze ATP between the a and b phosphates (yielding AMP and PPi). ∆G°’ of phosphate hydrolysis is -31 kJ/mol for ATP + H2O --> ADP + Pi, and ∆G°’ of phosphate hydrolysis is -46.5 kJ/mol for ATP + H2O...
