Chains of amino acids, folded into specific shapes. Enzymes, structural proteins (e.g., collagen), antibodies, and muscle proteins are examples. Nucleic Acids: Nucleotides, with a sugar, base, and phosphate group, form the structure of nucleic acids. DNA (deoxyribonucleic acid) and RNA (ribonucleic acid) are nucleic acids. DNA consists of two strands forming a double helix and stores hereditary information. RNA is involved in protein synthesis and can act as an enzyme. ATP (Adenosine Triphosphate): Important for energy transfer within cells. Composed of a single nucleotide with two extra energy-storing phosphate groups. The observations of Schleiden, Schwann, and Virchow form the ______ theory, which has three parts: 1.All living things are made of one or more cells. 2.Cells are the basic units of structure and function in organisms. 3.All cells arise from existing cells.

Cytoskeleton: Microscopic fibers in the cytoplasm provide structural support to various cell structures. 3.Information center: All cells possess DNA, offering instructions for protein synthesis, regulation of cellular activities, and enabling the reproduction of cells. 4. Ribosomes: Most cells contain ribosomes, essential structures where proteins are synthesized, contributing to various cellular functions. 7 Lecture 5 General Biology There are two basic types of cells: Prokaryotes: meaning literally “before the nucleus.” They contain a single, large molecule of DNA not located in a membrane-bound nucleus, but found in a nuclear region, or ______

All eukaryotes (“true nucleus”) have cells with a membrane-bound nucleus containing ______.In addition, eukaryotic cells contain many other structures called organelles (“little organs”) that perform specific functions 8 Lecture 5 General Biology Cells membrane: The fluid-mosaic model, developed by Singer and Nicolson in 1972, describes the cell membrane as a dynamic double layer of proteins and phospholipids, exhibiting fluidity rather than solidity.This phospholipid bilayer forms a fluid sea were various proteins act like icebergs.The term mosaic reflects the diversity of proteins dispersed in the bilayer, constituting the outer boundary of the cell.
