3. Metabolism cab ne defined as the set of complex chemicla changes occuring within the cells of living organisms and are vital for maintaining life. It can further be categorized in two groups: (a) Anabolism; and (b) Metabolism.
Anabolism is defined as the series of reactions involved in the synthesis of complex molecules from small molecules. In contrast, catabolism is a set of reactions which involve breakdown and hydrolysis of complex biomolecules like proteins and carbohydrates into monomers such as amino-acids and glucose, respectively. The major differences between anabolism and catabolism has been outlined below.
4. First Law of Thermodynamics: According to the first law "total energy of an isolated system is conserved."
5. Second Law of thermodynamics: The second law states that spontaneous chemical reactions in biological processes which mainly occur at constant temperature and pressure always lead to decline in free energy. This loss in free energy can be in the form of heat (enthalpy) or can vcause increase in entropy (randomness).
Free energy is defined as the energy possessing the ability to perform work.
6. When energy changes from one form to another, some of the energy that can be used to do work is laways lost. the loss of energy is mostly in the form of heat.
7. The main differences are listed below.
8. ATP (Adenosine triphosphate), also known as energy currency of the cell and synthesized during the process of respiration, is composed of an adenine base, ribose sugar moiety and 3 phosphate groups. The energy is stored in the form of high energy phosphate bond linking the terminal phosphate group to the rest of the molecule. Hydrolysis of the high energy phosphate bonds releases energy which is used by the cells to drive endergonic reactions for cellular maintenance and homeostasis.
9. The hydrolysis of ATP is exergonic reaction providing the energy needed to drive endergonic reactions.
10. Hydrolysis of ATP:
ATP + H2O ? ADP + Pi
Pi stands for inorganic phosphate, which is utilized in many biosynthetic processes for the formation of GTPs, ribonucleotides as well as in the phosphorylation of proteins.
ANABOLISM CATABOLISM Synthesis of complex molecules from monomers Breakdown of complex molecules into subunits and monomeric forms Constructive metabolism Destructive metabolism Involve reductions and is an endergonic process Involve oxidation and are exergonic in nature Divergent and generate variety of molecules convergent and breakdown occurs to generate monomers Requires NADPH Requires NAD+Related Questions
