respiration is respiration without oxygen; the process uses a respiratory electron transport chain but does not use oxygen as the electron acceptors. Cells that use it Aerobic respiration occurs in most cells. Anaerobic respiration occurs in bacteria‚ yeasts‚ some prokaryotes‚ erythrocytes (red blood cells)‚ and in muscle cells. Production of lactic acid Does not produce lactic acid Produces lactic acid (in lactic acid fermentation but not in alcoholic fermentation) Amount of energy released High (36-38

nature of enzyme actions using live yeast cells as our source of sucrose. The enzyme will then break the sucrose into one molecule of glucose and fructose. Because sucrose is a large molecule that cannot enter most cells‚ yeast will produce sucrase and secrete it into cell membranes. The sucrose will be hydrolyzed into small six-carbon monosaccharide’s which can enter into the cell membranes. The sucrose can be obtained from a 0.5 percent solution of “dry baker’s yeast in water”. In parts A and B‚

of enzymes from yeast in 2 steps: first sucrose (a disaccharide whose structure is in your textbook) is broken down to two monosaccharides‚ glucose and fructose. These monosaccharides are then converted into ethanol and carbon dioxide. * Materials 250-mL Erlenmeyer flask 250-mL Beaker Bruchner funnel Fermentation apparatus Distillation apparatus Vacuum filtration assembly Water Sucrose Potassium phosphate Celite Disodium hydrogen phosphate Dried baker’s yeast * * Procedure

Microbial Diversity and Ubiquity Microorganisms are microscopic organisms that are so small that that they can only be visualized by the aid of a compound-brightfield microscope. While we generally cannot see individual microorganisms with the naked eye‚ they are present in virtually every habitat known to man. Microorganisms can be prokaryotic—the bacteria or eukaryotic—the algae‚ protozoa or fungi. While viruses are acellular they are also studied in the scope of microbiology because

There are one organism pityrosporum ovale that is yeast fungi which lead in this disease and play major role in causing this disease.

Introduction to sexual reproduction in humans Reproduction is the process by which humans gives rise to new individuals. Sexual reproduction is the process that involves the fusion of two gametes‚ sperm (male gamete) and egg (female gamete). In human these gametes are produced in different sexes‚ the male and female. Reproduction in humans is performed by reproductive systems‚ the male and female reproductive systems. The main organs of male reproductive system are testis and gonads and of female
