Study Notes
Aerobic Respiration and Photosynthesis
- In aerobic respiration, oxygen is the terminal electron acceptor.
- The light reactions of photosynthesis produce ATP, NADPH, and O2.
Energy Flow and Genetic Material
- Oxidative phosphorylation is the process by which energy from electron flow is conserved in the form of ATP.
- In microbial cells, the flow of genetic material occurs from DNA through RNA to proteins.
- During DNA replication, a new copy of a DNA molecule is precisely synthesized.
Tetanospasmin and Exotoxins
- Tetanospasmin is a heat-labile protein, a neurotoxin, and can be a toxoid.
- Botulinum toxin is the most toxic exotoxin.
Clostridium Botulinum Food Poisoning
- Clostridium botulinum food poisoning occurs due to both invasion of bacteria in the intestine and preformed toxin.
