The World of the Cell, Fourth Edition, helps students understand and enjoy cell biology. Focusing on core concepts, the authors present solid information without being encyclopedic. Thoroughly updated, the Fourth Edition continues the text's tradition of clarity and readability, and extends its effectiveness as a learning tool by dividing material in each chapter into a series of conceptual sections, each introduced by a sentence heading that summarizes the concept.

1. A Preview of the Cell.
2. The Chemistry of the Cell.
3 The Macromolecules of the Cell.
4. Cells and Organelles.
5 Bioenergetics: The Flow of Energy in the Cell.
6 Enzymes: The Catalysts of Life.

II. MEMBRANES AND CELL SIGNALING.

7. Membranes: Their Structure, Function, and Chemistry.
8. Transport Across Membranes: Overcoming the Permeability Barrier.
9. Signal Transduction Mechanisms: I. Electrical Signals in Nerve Cells.
10. Signal Transduction Mechanisms: II. Messengers and Receptors.
11. Beyond the Cell: Extracellular Structures, Cell Adhesion, and Cell Junctions.
12. Intracellular Compartments: The Endoplasmic Reticulum, Golgi Complex, Endosomes, Lysosomes, and Peroxisomes.

III. Energy Flow in Cells.

13. Chemotrophic Energy Metabolism: Glycolysis and Fermentation.
14. Chemotrophic Energy Metabolism: Aerobic Respiration.
15. Phototropic Energy Metabolism: Photosynthesis.

IV. Information Flow in Cells.

16. The Structural Basis of Cellular Information: DNA, Chromosomes, and the Nucleus.
17. The Cell Cycle: DNA Replication, Mitosis, and Cancer.
18. Sexual Reproduction, Meiosis, and Genetic Recombination.
19. Gene Expression: I. The Genetic Code and Transcription.
20. Gene Expression: II. Protein Synthesis and Sorting.
21. The Regulation of Gene Expression.

V. The Cytoskeleton and Cell Motility.
