How do Archaeans obtain energy and what molecule is formed during this process?

Archaeans obtain energy by absorbing sunlight using their membrane pigment, bacteriorhodopsin. This reaction leads to the formation of the energy molecule Adenosine Triphosphate (ATP). Signup and view all the answers

Study Notes

Bacterial Shapes

Spiral shaped: Spirilla (Example: Campylobacter jejuni)
Comma shaped: Vibrios (Example: Vibrio cholerae)
Corkscrew shaped: Spirochetes (Example: Treponema pallidium)
Round shaped: Cocci
Rod shaped: Bacilli

Archaea

Single cellular, microscopic organisms
Prokaryotes
Belong to kingdom Archaebacteria (also known as Archaea)
Size: 0.1 to 15 μm in diameter and up to 200 μm long

Characteristics of Archaea

Based on habitat, Archaea are divided into:
- Halophiles: live in salty environments (Example: Halobacterium)
- Methanogens: methane-producing organisms (Example: Methanococcus)
- Thermophiles: live in extremely hot temperatures (Example: Alicyclobacillus)
- Psychrophiles: cold-loving organisms (Example: Listeria monocytogenes)

Characteristics of Micro-organisms

Prokaryotes: Bacteria and Archaea
Eukaryotes: Protozoa and others
