Process of creating RNA from DNA
How are amino acids linked together
Peptide bonds that form chains
name the process of forming proteins from RNA
20 tRNA's in a cell connect with 1 amino acid (process of translation).
Differences between RNA and DNA
- 1) RNA is mobile, and DNA is restricted to the nucleus.
- 2) RNA is usually single straned (ssRNA), and DNA is usually doubled.
2 parts of a closed system
- 1) Limited resources and
- 2) Waste buildup
- =growth curve
4 phases of growth curve
- 1) lag
- 2) log
- 3) stationary
- 4) death
Formula for calculating Population during Log phase
(#of starting organisms)X2^(#generations)
What causes Oxygen toxicity?
Reactive Oxygen Species (ROS)
Microorganisms with ____ & ____ are protected against oxygen toxicity?
- 1) catalase
- 2) Peroxidase
- 3) SOD Superoxide Dismutase needs another
2 things catabolic reactions do:
- Breaks down complex molecules
- Releases energy
2 things anabolic reactions do:
- 1)constructs molecules from simple ones
- 2) Requires energy.
an aerobe that requires oxygen
Requires less oxygen than obligate aerobe
Preferes oxygen, but doesn't mind lack of oxygen.
Indifferent of oxygen levels and grows well with or without oxygen
die in presence of oxygen
What do catabolic reactions release, and Anabolic reactions use?
Carbon, Electrons, and energy
organic molecules are composed of
carbon oxygen and hydrogen
4 major groups of organic molecules
- 1) Carbohydrates
- 2) Amino acids/proteins
- 3) Nucleic acids (RNA & DNA)
- 4) Lipids
Organism that gets energy from organic or inorganic chemicals
