Microbiology Exam 1 Newsome questions and answers | 100%
Active transport - Use of energy to transfer across cell membrane, enters cell unchanged
Aerobic Respiration - requires oxygen
glycolysis --> Krebs cycle --> respiratory chain --> O2 is final acceptor for electron
Alexander Fleming - Scottish microbiologist credited for creation of antibiotics (late 1930s)
anabolism - uses energy to synthesize molecules using enzymes
Anaerobic bacteria - do not grow fast
produce odors
most of intestinal bacteria
cause of variety of diseases
PERIODONTAL DISEASE
Anaerobic Respiration - does not require oxygen
glycolysis --> respiratory chain
uses something other than O2 as terminal electron acceptor
not as much energy generated and bacteria multiply slowly
Tetanus/botulism
Antibiotic (definition/functions) - chemical substance from a microorganism that can inhibit/kill
another microbe even in minute amounts
inhibition of:
cell wall synthesis
protein synthesis
DNA synthesis
metabolism
, cytoplasmic membrane function
Anton van Leeuwhoek - invented the microscope -- first person to see bacteria 1600s
Bacillus anthracis - anthrax -- "poor man's nuke"
Bacteria features - Capsule (slime layer, glycocalyx) -- promotes attachment thus promoting
colonization, promotes antibiotic resistance, promotes formation of biofilms, SERVE IN
VACCINE PREP
Flagella -- moves very slow but fast relative to its size
Fimbriae -- small hair-like structures that promote attachment
Pili -- promotes conjugation and can promote attachment (Haemophilus influenzae type B or
HiB)
catabolism (def/types/stages) - yields energy using enzymes
respiration or fermentation
Glycolysis --> breakdown of sugars
Krebs Cycle --> main products are NADH and FADH2
Electron Transport Chain --> located in membrane of mitochondria and cell membrane of
bacteria
Catabolism for respiration/fermentation - PREFER carbohydrates (cheesecake)
NOT PREFERRED lipids and proteins
Cell Membrane - Euk cells just have cell membrane
2 layered structure composed of lipids and proteins (SEE DIAGRAM)
