 Basics of Cell Biology: 6 Science DVD Programs
Biochemistry I: Atoms, Ions, and Molecules science DVD - Begins by
describing the basic structure of atoms and how ions are formed as
atoms gain or lose electrons. Molecules and the covalent bonds that
hold them together are then investigated. 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 a number of unique characteristics
critical to life. A look at the concept of pH and the role of buffers
concludes the program. Biochemistry II: Carbohydrates, Proteins, Lipids, and Nucleic Acids
science DVD - Starts by explaining how polymers are synthesized out of smaller
monomers through dehydration reactions that release H2O molecules in
the process. The program goes on to look at the role of carbohydrates
in energy storage and as structural building blocks; the use of lipids
in synthesizing plasma membranes, fats and steroid hormones; proteins
in their role as enzymes, hormones, and structural materials; and
nucleic acids use in storing information and transferring energy. Cells: The Structure of Life science DVD- First explains the
difference between prokaryotic and eukaryotic cells and then explores
in detail 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. The program concludes by
looking at how cellular shape varies with cellular function. Cell Membranes: The Boundaries of Life science DVD - Begins 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. The
concepts of simple and facilitated diffusion, passive and active
transport, and osmosis are illustrated. Endocytosis and exocytosis, the
role of contractile and central vacuoles, and how desmosomes and tight
junctions tie cells together and how plasmodesmata and gap junctions
facilitate communication are explained. Photosynthesis: Transforming Light to Life science DVD - First
documents how scientists unraveled the mystery of photosynthesis and
then examines the structural adaptations in leaves that facilitate
photosynthesis, the nature of visible light, and the structure of
chloroplasts before going on to explain how the light dependent
reactions that occur in photosystems I and II produce ATP and other
high energy molecules that are then used to produce glucose via the
light independent C3 and C4 cycles which are compared and contrasted to
one another.
Glycolysis and Cellular Respiration: The Biology of Energy
science DVD - After looking at the processes of glycolysis and fermentation the
program then looks in detail at 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 program
continues with an in-depth examination of the citric acid cycle. An
exploration of the endosymbiotic hypothesis which offers an explanation
of how photosynthesis and cellular respiration arose in eukaryotic cells concludes the program.
