What is energy? Give its forms. How is it measured? Discuss laws of thermodynamics. Write note on activation energy. Write note on enzyme. Give structure of enzyme. Describe function of…
TERMS DEFINITIONS Energy The capacity, to do work is called energy. Work Work is the transfer of energy. Thermodynamics The study of energy is called thermodynamics…
Animals make ATP in two ways: Substrate level phosphorylation The synthesis of ATP during reaction of glycolysis and Krebs cycle is called substrate level phosphorylation. ATP formation from ADP and…
The major energy L.:rrency of all cells is adenosine triphosphate (ATP). ATP plays a central ro:(.. ( energy currency in all organisms. So it appeared early in the iNstor. .M…
Cofactors The metal ions which are loosely attached with the enzymes are called cofactors. These metal ions are Ca-2, mg-2, mn-2, 2, Cu" and Zr12. These metal ions change a…
An enzyme is a biological catalyst that can accelerate a specific chemical reaction by lowering the activation energy but remain unaltered in the process. Most enzymes are proteins. Some are…
Th re are two laws of thermodynamics: First law of thermodynamics It i also called the law of energy conservation. It states that energy can neither be created nor destroyed,…
