Are bacteria generally more resistant to antibiotics when they grow in suspension or in a biofilm? Why? Draw and label a typical bacterial growth curve.
Bacterial metabolism results in products that are used for the synthesis of cellular constituents, like peptidoglycan, LPS, proteins, nucleic acids, etc.. You learned about the
Fermentation refers to the breakdown of a monosaccharide to pyruvic acid and then usually to lactic acid. It is also called the glycolytic cycle and
The growth of most medically important organisms is enhanced by the presence of oxygen, which acts as the hydrogen acceptor in the final stages of
Bacteria cannot reproduce without a source of energy and the building blocks of cellular constituents (e.g. amino acids, carbohydrates, lipids). Minimum requirements for growth are
Growth Cycle Bacteria reproduce by binary fission: one cell divides to form 2 progeny cells. This results in exponential (logarithmic) growth. 1. Number of cells
Learning Objectives: You should be able to: explain how bacteria reproduce and the potential effects of a short vs. a long generation time on the
Study Questions List 8 major structural differences between prokaryotes and eukaryotes and/or draw a picture of each cell type that shows these differences (don’t forget
Capsule Gelatinous layer surrounding the bacterial cell; gives many bacterial colonies a mucoid appearance. Composed of polysaccharide (except in Bacillus anthracis) which varies among bacteria
