Evolutionary Bioenergetics of Protocells Introduction Bioenergetics is central to our understanding of living systems‚ though there has been very less research in field of finding the origins of life. Understanding the origin of cellular life on Earth requires the discovery of plausible pathways for the transition from complex prebiotic chemistry to simple biology‚ defined as the emergence of chemical assemblies capable of Darwinian evolution. A coherent pathway which starts from no more than

Prokaryotes are organisms whose cells lack a nucleus and membrane-enclosed organelles. Most prokaryotes are small‚ single-celled organisms that have a relatively simple structure. Prokaryotic cells are surrounded by a plasma membrane‚ but they have no internal membrane-bound organelles within their cytoplasm. The absence of a nucleus and other membrane-bound organelles differentiates prokaryotes from another class of organisms called eukaryotes. Prokaryotes and Eukaryotes are similar in their chemical

Micro-organisms are very dangerous but they can also help you. They cure you but they can also kill you. They have been around longer than dinosaurs. They can adjust to almost any environment. There are six types of microbes. There is Archaea‚ Bacteria‚ Fungi‚ Protista‚ Viruses and Microbial mergers. Microbes play a big part in people’s health and in the environment. Good Microbes play a big part in people’s health. They mostly play bad parts in health even though the ratio of bacteria

However‚ organisms such as plants‚ certain bacteria (cyanobacteria)‚ and algae can carry out photosynthesis as well. The three domains that are able to carry out some type of photosynthesis would therefore be‚ Eukarya‚ Bacteria and Archaea. These organisms are known as photoautotrophs‚ which are autotrophs that use carbon and sunlight to synthesize chemical energy in the form of carbohydrates. (5 | Photosynthesis) The objective of the photosynthesis lab is to evaluate the process and

Heterotrophs are any organism that consumes organic carbon and energy that is fixed by primary producers. This unit discussed an extremely important pyramid‚ somewhat like a food chain that categorizes heterotrophs. 1st level of the pyramid are herbivores‚ 2nd level are carnivores. Eukaryotes are single celled or multi-celled‚ recapped in this unit‚ the primary consumers are the herbivores‚ the secondary consumers are the herbivore consumers‚ and the tertiary consumers are the top predators.

share five basic properties. They are: cellular organization‚ metabolism‚ homeostasis‚ growth and reproduction‚ and heredity. (Johnson‚ 2010‚ p. 15) Those living things are categorized into six groups called Kingdoms. The six kingdoms are Bacteria‚ Archaea‚ Protista‚ Fungi‚ Plantae‚ and Animalia. Viruses do not belong to the above 5 kingdoms of life. They are much smaller and much less complex than cells. They are macromolecular units composed of DNA or RNA surrounded by an outer protein shell
