Explain what REDOX reactions are and their importance to the cell.

Which of the following statements is true of chemoautotrophs? O They use hydrogen sulfide as their hydrogen source for the photosynthesis of their organic compounds. O They "feed themselves" by obtaining energy from the chemical bonds of organic molecules. O They oxidize inorganic compounds to obtain energy to drive the synthesis of their organic compounds. O They live as decomposers of inorganic chemicals in organic litter. O They obtain their energy from oxidizing chemical compounds and get their carbon skeletons from organic compounds.

Arrange the following steps in the experiment regarding the effect of temperature on fermentation (anaerobic respiration) 1 4 Sugar and water are mixed Measure the height of foam is measured Test tubes are placed in water bath Yeast and glucose solution are mixed Graph the height vs temperature

Enzymes are denatured at low temperatures. True False Previous Page Next Page Page 31 of 50

A culture medium consisting of known amounts of glucose, NaCl, and ammonium and potassium phosphate would be an example of:

A prokaryote that lacks peptidoglycan, is positive for branched hydrocarbons, thrives in hot sulfur springs at 90 degrees C, would be facultative anaerobe. an extreme acidophile. an extreme halophile. an extreme thermophile.

give an example of a metabolic reaction of a drug or endogenous substance for SN1reaction, E1 reaction, and radical reaction. Then determine the electrophile and nucleophile.The metabolic reaction needs to occur within the body no in vitro tube reactions. Considerthat most reactions occurring in the body will require an enzyme as a catalyst.

Using correct terminology about water activity, explain why making jam is a good way to preserve berries. When you seal a jar of jam (as in canning), in what additional ways are you preventing microbial growth?

Pseudomonas aeruginosa is capable of aerobic respiration and anaerobic respiration but not fermentation. It can produce H2Sdoes not produce tryptophanase, and is motile by a flagellum . Based on the above characteristics, describe your expected results for Pseudomonas aeruginosa in a SIM deep .
