490792 - Biochemistry I: Atoms, Ions, and Molecules - This program begins by describing the basic structure of atoms and how ions are formed as atoms gain or lose electrons. Next up is an investigation of molecules and the covalent bonds that hold them together. The program then explains the difference between organic and inorganic molecules, polar and non-polar molecules, and how the hydrogen bonds that form between polar H2O molecules provide water with unique characteristics that are critical to life. A look at the concept of pH and the role of buffers concludes the program. 27 minutes.
490793 - Biochemistry II: Atoma, Ions, and Molecules. This helpful video begins by explaining how polymers are synthesized out of smaller monomers through dehydration reactions that release H2O molecules in the process. Next up is the role of carbohydrates in energy storage and as structural building blocks, followed by the use of lipids in synthesizing plasma membranes, fats, and steroid hormones; and the role of proteins as enzymes, hormones, and structural materials. Finally, the program looks at the use of nucleic acids use in storing information and transferring energy. 36 minutes.
490794 - Cells: The Structure of Life - See the difference between prokaryotic and eukaryotic cells, and explore the structure and function of the major organelles found in eukaryotic cells. Examined organelles include the nucleus, ribosomes, smooth and rough endoplasmic reticulum, the Golgi complex, lysosomes, chloroplasts, mitochondria, plastids, contractile and central vacuoles, cilia, flagella, and the microtubules, microfilaments, and intermediate filaments that make up the cytoskeleton. Finally, see how cellular shape varies with cellular function. 32 minutes.
490795 - Cell Membranes: The Boundaries of Life - The fascinating world of cells is explored in this short program, first by examining cell wall structure and the major functions of cellular membranes before introducing the fluid mosaic model of the phospholipid bilayer and transport, recognition, and receptor proteins. Next are the concepts of simple and facilitated diffusion, passive and active transport, and osmosis. Endocytosis and exocytosis, the role of contractile and central vacuoles, the way desmosomes and tight junctions tie cells together, and a look at how plasmodesmata and gap junctions facilitate communication conclude the program. 31 minutes.
490796 - Photosynthesis: Transforming Light to Life - Watch scientists unravel the mystery of photosynthesis and examine the structural adaptations in leaves, the nature of visible light, and the structure of chloroplasts in this fascinating DVD. It explains how the light-dependent reactions that occur in photosystems I and II produce ATP, then compares other high-energy molecules that produce glucose via the light-independent C3 and C4 cycles, which are compared and contrasted to one another. 30 minutes.
490797 - Glycolysis and Cellular Respiration: The Biology of Energy - After looking at the processes of glycolysis and fermentation, it delves into cellular respiration, beginning with the structure of mitochondria. Following the entry of pyruvic acid into the mitochondrial matrix and the formation of acetyl CoA, the DVD continues with an in-depth examination of the citric acid cycle. Finally, the program ends by exploring endosymbiotic hypothesis and offers an explanation of how photosynthesis and cellular respiration arose in eukaryotic cells. 27 minutes. |
