Bioenergetics is the scientific study of the flow and transformation of energy within living organisms. It explores how cells acquire, convert, store, and utilize energy to sustain life processes. Bioenergetics encompasses the metabolic pathways, reactions, and energy transfers that occur during cellular activities such as growth, reproduction, response to stimuli, and maintaining homeostasis. The central … Read more
Amino acids are organic compounds that serve as the building blocks of proteins and play essential roles in various biological processes. They are crucial for the structure, function, and regulation of cells and tissues within living organisms. Amino acids are characterized by functional amino (-NH2) and carboxyl (-COOH) groups. Classification of Amino acids 1. Based … Read more
Proteins are large, complex biomolecules that play fundamental roles in the structure, function, and regulation of cells and organisms. They are involved in numerous biological processes and are essential for life. Proteins are composed of amino acid chains folded into specific three-dimensional structures, exhibiting remarkable function diversity. Classification of proteins Proteins can be classified based … Read more
Nucleic acids are essential biomolecules that play a central role in storing, transmitting, and expressing genetic information in living organisms. They actively serve as the molecular blueprint for synthesizing proteins and play a crucial role in various cellular processes essential for the functioning and reproduction of cells. Classification of Nucleic Acids There are two main … Read more
Lipids constitute diverse organic molecules essential to living cells’ structure and function. They play critical roles in energy storage, insulation, protection, and signaling within biological systems. Lipids are hydrophobic, meaning they are not soluble in water. Classification of LIpids Lipids are broadly classified into several categories: Lipids are a diverse group of organic compounds characterized … Read more
Carbohydrates play crucial biological roles in living organisms, serving as essential macromolecules with diverse functions. Some key biological roles of carbohydrates include: 1. Energy Source Glucose Metabolism: Carbohydrates, especially glucose, are a primary energy source for cellular processes through glycolysis and cellular respiration. Energy Storage: Excess glucose is converted into glycogen (in animals) or starch … Read more
Carbohydrates exhibit various chemical properties based on their molecular structure and functional groups. Here are some key chemical properties of carbohydrates: 1. Reactivity with Acids and Bases Carbohydrates, particularly monosaccharides, can react with acids and bases. For example, hydrolysis of glycosidic bonds can occur in an acid, breaking down disaccharides or polysaccharides into monosaccharides. 2. … Read more
Carbohydrates are organic compounds of carbon, hydrogen, and oxygen atoms, typically with a hydrogen-oxygen atom ratio of 2:1 (as in water). They serve as a primary energy source for living organisms and play essential structural and functional roles in cells. Carbohydrates include sugars, starches, and fibers and can be classified based on their chemical structure … Read more
