1 Building Blocks and their Interactions Atoms and Elements Form the basis of all chemical compounds including biomolecules Chemical Bonds Allow atoms to interact forming molecules with unique properties Organic Molecules Built upon a carbon backbone forming the core of life Monomers and Polymers Monomers are simple building blocks that join to form larger complex polymers 2 Biomolecules and their Functions Carbohydrates Composed of carbon hydrogen and oxygen providing energy structural 3 support and cell recognition eg glucose cellulose Lipids Diverse group including fats oils steroids and phospholipids Fats store energy oils provide insulation steroids act as hormones and phospholipids form cell membranes Proteins Composed of amino acids forming complex structures with diverse functions including catalysis transport structural support and signaling eg enzymes antibodies Nucleic Acids Composed of nucleotides storing and transmitting genetic information essential for protein synthesis eg DNA RNA 3 Waters Crucial Role Polarity and Hydrogen Bonding Waters polar nature allows it to act as a solvent dissolving and transporting molecules throughout the body Hydrogen bonding between water molecules gives it a high surface tension and makes it an effective temperature moderator Hydrophobic and Hydrophilic Interactions Waters polarity affects interactions with other molecules Hydrophobic molecules like lipids avoid contact with water while hydrophilic molecules like sugars readily dissolve in water These interactions play crucial roles in the folding of proteins and the formation of cell membranes 4 Energy and Metabolism Enzymes Biological catalysts lowering activation energy and speeding up biochemical reactions allowing metabolic pathways to proceed efficiently Metabolic Pathways Series of interconnected reactions either catabolic breaking down large molecules into smaller ones releasing energy or anabolic building up complex molecules requiring energy ATP The primary energy currency of cells providing energy for various cellular processes including muscle contraction protein synthesis and active transport Photosynthesis Lightdriven process converting light energy into chemical energy in the form of glucose fueling the food chain Cellular Respiration Breakdown of glucose in the presence of oxygen releasing energy and generating ATP providing energy for cellular functions 5 Genetic Information and Protein Synthesis DNA Contains genetic instructions passed from one generation to the next guiding the development and functioning of organisms RNA Messenger molecule carrying genetic instructions from DNA to ribosomes where protein synthesis takes place Transcription The process of copying DNA into RNA allowing genetic information to be accessed and utilized 4 Translation The process of decoding RNA to synthesize proteins using the genetic code to assemble amino acids in a specific order 6 Cell Structure and Function Plasma Membrane The outer boundary of a cell selectively regulating the passage of molecules in and out of the cell maintaining homeostasis Organelles Specialized compartments within cells performing specific functions contributing to the overall functioning of the cell eg mitochondria nucleus Golgi apparatus endoplasmic reticulum Cytoplasm The gellike substance filling the cell providing a medium for organelles to function and for biochemical reactions to occur Cell Signaling Communication between cells allowing them to respond to their environment and coordinate their actions influencing growth development and immunity 7 Biotechnology and its Applications Genetic Engineering The manipulation of genes for various purposes including developing diseaseresistant crops producing therapeutic proteins and diagnosing diseases Biotechnology Products A wide range of products derived from biological processes including pharmaceuticals diagnostics biofuels and agricultural products
