ULTRASTRUCTURE OF MITOCHONDRIA Dr. Rathod L. R. Assistance Professor Department of Botany Mahatma Phule Arts, Science & Commerce College Panvel Unversity of Mumbai Date – 19/09/2011. Mitochondria.

?Kingdom for virus? (Prokaryota & Monera). Virus Ch 18.1 Prokaryotes = no membrane bound organelles (no nucleus or mitochondria). Warts are a skin virus!. Virus structure :. Protein Coat DNA or RNA for replication Adsorb-tion site Host specific. Nonliving Not cells

bacteria cells. Types of cells. Prokaryote - no organelles. Eukaryotes - organelles. animal cells. plant cells. Animal cell. Bacterial cell. Cell size comparison. most bacteria 1-10 microns eukaryotic cells 10-100 microns. micron = micrometer = 1/1,000,000 meter

01.20.10 Lecture 4 Cellular Building Blocks: Lipids and Membranes. Membranes form many compartments in the cell. Biological membranes are composed of a lipid bilayer. Membrane lipids are amphipathic molecules. Membrane lipids are amphipathic

In Haiti in 2010…. Haiti cholera death toll passes 900 (cnn.com) Health workers alarmed over trend in Haiti’s cholera outbreak (cnn.com) Cholera deaths up in Haiti, with worst to come (nytimes.com).

Western Analysis. Laboratory procedure that allows you to:. 1. Verify the expression of a protein. 2. Determine the relative amount of a protein present in different samples. 3. Analyze protein-protein interactions. Two Main Types of Westerns. 1. Denaturing (Most Commonly Used).

Drugs and Drug Action. Definition – Drugs. Chemicals (not light, sound, radiation, magnetic field)…… fragrance? Prevent disease or assist in restoring health. History. Originated from natural products Examples include opium, belladonna, cinchona, marijuana, digitalis, quinine, ………….

Lysosomes. The cell’s recycling centers. Lysosome Structure. Membrane-bound Contains powerful digestive enzymes If membrane broke open, enzymes would destroy cell Size 0.05 to 0.5 micrometers in diameter Proteins embedded in membrane

Pathogen Removal or Inactivation. Technical Advisory Panel Reclaimed Water Rule Jim McCauley (360) 407-7468 jima461@ecy.wa.gov. Pathogen Removal/Inactivation. Bacteria Total coliform Fecal coliform E. coli Enterococci Protozoans Giardia lamblia Cryptosporidium Viruses

Prebiotic Evolution. Chapter 18. Until about 300 years ago people believed in the idea of spontaneous generation –that life comes from non-living material. 1668 Francesco Redi proved that magots did not come from rotting meat. Could microorganisms arise spontaneously?

Topic 2: Cells Topic 1: Cells Membranes. blog.lib.umn.edu. Draw and label a diagram to show the structure of membranes (1). Explain passive transport across membranes by simple diffusion and facilitated diffusion (3).

Introduction, Review of Biomolecules. Lecture 1, Medical Biochemistry. Lecture 1 Outline. Review some basic chemical nomenclature and concepts Review the structural and functional features of different biomolecules Discuss the human genome project and the future of molecular medicine .

A View of the Cell. Dr. Stafford 2016. A View of the Cell. Before microscopes people believed in curses and the supernatural as the cause of diseases Microscopes opened a whole new world – Microorganisms – organisms only seen by microscope Cells – the building blocks of all living organisms.

Organismal Development Part 3. Male Animals. Mitochondrion. Intermembrane space. Outer membrane. Free ribosomes in the mitochondrial matrix. Inner membrane. Cristae. Matrix. Mitochondrial DNA. 100 nm. Phermones. Earthworms are hermaphrodites. Protogynous (Male is blue).

Prototheria (monotremes). Metatheria (marsupials). The 3 subclasses of mammals differ strikingly in their modes of reproduction. Eutheria (placentals). Monotremes – Lay eggs Cloaca No nipples. Ovaries larger (relative to body size) than other mammals

Cell Transport Systems. Diffusion. Mixing of materials by their own random motion Mixing occurs from an area of high to low concentrations. Osmosis. Basically the diffusion of H 2 O through a membrane Since H 2 O molecules are small – they can pass through membranes (even non-polar part)

4. Functional Anatomy of Prokaryotic and Eukaryotic Cells. Eukaryotic Cells. Comparing prokaryotic and eukaryotic cells Prokaryote comes from the Greek words for prenucleus . Eukaryote comes from the Greek words for true nucleus. Figure 4.22a. Figure 4.22 - Overview. Figure 4.22a.

The Eukaryotic Cell. Chapter 3 Section 2 Notes . Eukaryotic Cells. All eukaryotic cells have linear DNA, a nucleus, and membrane-bound organelles All eukaryotic cells have the following organelles in common: Cell membrane Only plant cells and algae have Cytoskeleton 1. cell walls
