BIO1130 - Archean Eon Keywords - Shivan Desai
Aerobic:
Requiring oxygen to survive, and perform life functions. (Aerobe-Organisms that require oxygen for cellular respiration.)
Aerobic respiration is a characteristic of eukaryotic cells, even though prokaryotic cells can use aerobic respiration as well.
Helps produce allot of ATP.
Example: Kreb’s Cycle.
Anaerobic:
Doesn’t require oxygen to survive and perform life functions. (Anaerobe-Organisms that don’t require oxygen to live)
Anaerobic respiration occurs in mitochondria.
Prokaryotes are capable of anaerobic respiration.
Doesn’t produce allot of ATP, hence it is effective for single cell organisms.
Example: Glycolysis.
Antibiotic resistance:
Resistance of a microorganism to survive through the exposure of an antibiotic.
Resistance is generally due to a genetic mutation of a bacteria, or evolutionary stress.
A bacteria with many resistance genes may be referred to a superbug, or super bacterium.
Archaea:
Single celled organisms, who are a part of 1/3 domains of life.
Contains no nucleus or organelles.
Can survive in extreme conditions
First forms of life to appear on Earth.
Example: Extremophiles. Applies to theory which Archaea appear from outside of Earth, due to their extreme environmental resistance capabilities.
ATP sythetase (synthase):
Couples the favourable transports protons across a membrane to create ATP. Also called the “Proton Pump”
Creates a electrochemical gradient.
Autotroph:
Organism which is capable to make its own energy.
Production of own food from CO2
Synthesizes organic carbon molecules using inorganic carbon. (CO2)
Example: Plant; Performs photosynthesis. Other Example: Sulphur bacteria: bacteria may use other organic compounds (oxidation reactions, etc.)
Bacillus bacteria:
Bacteria which is rod-shaped, gram-positive, aerobic and anaerobic.
Found in soil and water.
Useful in antibiotics, as they can serve to protest the host from
