Some Important Points of Botany Thermodynamics:- Thermodynamics is the study of transformation that occurs in a collection of matter. First law of thermodynamics:- Total amount of energy in the universe is constent. Energy can never be created nor destroyed. But it can change from one form to another. Second law of thermodynamics:- Explains, Why the total amount of free energy is decling in the universe as whole. The law states the enrgy transfer or transformation of the energy makes the universe disordered. Some Energy is lost associated disorder of physical prosses or chemical reaction. The term enzyme was coined by Kuhne 1878 . There are approximately 3000 enzymes present in a cell. The molecular weight of enzymes ranges from 10,000 to more than 1,00,000 daltons. A complete enzyme is called Holoenzyme . Fisher suggested lock & key model for mechanism of enzyme action. Koshland proposed Induced fit hypothesis for mechanims of enzym action...
