Portage Learning Microbiology Exam #1
3 groups of Carbohydrates - Monosaccharide, Disaccharide, Polysaccharide
Adenine and Thymine - Complimentary bases, form two hydrogen bonds
All cells are compromised of - Macromolecules (building bloacks)
Amino Acid - Way proteins are formed by varying combinations, 20 different kinds
Animalia - multicellular eukaryotic organisms, heterotrophic, ability to move
Bacillus - Rod (e coli)
Bacteria - large cohort of prokaryotic microorganisms
Bacteria and Archaea - Prokaryotic
Bilayer (cell membrane) - Composed for amphipathic phospholipids (water loving heads and water
hating tails), tails face inward
Can DNA and RNA be found in the nucleus? - Yes
Can DNA and RNA leave the nucleus? - Only RNA. DNA is highly compact in the nucleus
Carbohydrates - Made of Carbon, Hydrogen, and Oxygen atoms (CH2O)n (# of carbon and oxygen is
always equal with the number of hydrogen levels doubled; C6H12O6)
Cell - Smallest, most basic biological unit of life
Cell membrane - Encloses the main body of the cell, permeable barrier surrounding the cytoplasmic
space of a cell
Cell membrane has a high level of - fluidity, lipids can move freely between the two layers, slower at
lower temps and faster at high temps
Cell membrane may also be referred to as - Plasma membrane or the cytoplasmic membrane
Cell wall - Found in bacteria, plants, fungi, and algae and help form the shape of the cell, provide
protection
Chloroplasts - double membrane-enclosed organelles specific to algae and plants, animal cells to not
contain chloroplasts, site of photosynthesis
Coccus - Round/spherical (streptococcus)
Combination of the cell membrane and the outer membrane are referred to as the - Cell envelope
Cytoplasm - Open volume within a cell, comprised mostly of water with dissolved substances
