n individual is waiting for a bus at the bus-stop. Suddenly he hears the big sound of a collision and sees that a car has lost control and is angerously approaching towards him. He runs for his life away from the bus stop holding his breath, generating a velocity of 10 eters/second. Calculate the amount (grams) of glucose used to generate this speed provided that all the energy was used for running. ssume his weight= 50kg, AG for ATP hydrolysis= -50 kJ/mole, Mol. Weight of Glucose = 180g/mol. netic energy = ½ mv2 where m=mass, v= velocity. Assume that friction, sound and other factors are negligible. grams
Thermochemistry
Thermochemistry can be considered as a branch of thermodynamics that deals with the connections between warmth, work, and various types of energy, formed because of different synthetic and actual cycles. Thermochemistry describes the energy changes that occur as a result of reactions or chemical changes in a substance.
Exergonic Reaction
The term exergonic is derived from the Greek word in which ‘ergon’ means work and exergonic means ‘work outside’. Exergonic reactions releases work energy. Exergonic reactions are different from exothermic reactions, the one that releases only heat energy during the course of the reaction. So, exothermic reaction is one type of exergonic reaction. Exergonic reaction releases work energy in different forms like heat, light or sound. For example, a glow stick releases light making that an exergonic reaction and not an exothermic reaction since no heat is released. Even endothermic reactions at very high temperature are exergonic.
