12. Briefly discuss the role of the electron transport chain in cellular respiration. In your explanation‚ discuss and identify key molecules involved in this process and explain their relationship which each other in terms of how they contribute to the main cellular purpose of this process. Electron transport chain plays a key role of in the production of oxygen in cellular respiration. ETC uses many enzymes located on the inner mitochondrial membrane during the production of oxygen.

Bacteria are the most ancient life forms‚ most bacteria are so small that under a light microscope you can only see them as little dots. Some groups however grow to larger sizes and have spectacular shapes (1). Bacteria are present in most habitats on the planet‚ growing in soil‚ water‚ acidic hot springs‚ radioactive waste‚ and deep in the Earth’s crust‚ as well as in organic matter and the live bodies of plants and animals (2). Bacteria is mostly thought of as a pathogen‚ while it is true that

What is biology? The study of living things (science of life) Describe characteristics found in all living organisms. * Living things are made of cells. * Living things obtain and use energy. * Living things grow and develop. * Living things reproduce

------------------------------------------------- The Processes of the nitrogen cycle Nitrogen fixation Atmospheric nitrogen must be processed‚ or "fixed" (see page on nitrogen fixation)‚ in order to be used by plants. Some fixation occurs in lightning strikes‚ but most fixation is done by free-living or symbiotic bacteria. These bacteria have the nitrogenase enzyme that combines gaseous nitrogen with hydrogen to produce ammonia‚ which is then further converted by the bacteria to make their own organic

Task one A). How do living things interact? Living things find a way to live off the land. Not with artificial flavouring or stuff like that. But it may not last unless we take good care of it. Living things interact by: 1). Viruses Learn about viruses and their surroundings‚ and how they are created. What is a Virus A virus s a small‚ NONLIVING particle that invades and then reproduces inside a living cell. Viruses are considered nonliving because they are not cells. They cannot: * use energy

research project aims to convert food waste into butanol fuel in the most efficient and most environment-friendly manner. *A separation process will be researched and designed to first separate simple sugars from the food waste using thermophilic fungi. The challenge is to create a process that needs little energy input and produces a limited or no amount of waste and pollutant*. The next portion of this research deals with taking this sugar and converting it into butanol fuel via fermentation. This

asexually – mitosis. Some use meiosis and sexual reproduction only in times of stress and then others reproduce sexually most of the time. What unites protists? The kingdom Protista contains all eukaryotes that don’t fit in animals‚ plants and fungi. See table on page 479 for distinguishing one phyla of protists from another. Generally protist that are heterotrophic are called protozoan and photosynthetic protists are called algae. Protists Reproduce Sexually and Asexually Typically

not have a significant effect on the basin. Mutualism is the interspecific interaction that benefits both species. Lichens are an example of mutualism in the Lake Tahoe Basin because Lichens are communities of algae and fungi. The algae makes oxygen for the fungi while the fungi produces food for the algae‚ interacting as a team to benefit both species. In commensalism‚ only one species is benefited during the interaction while the organism is neither harmed or benefited. Bacteria uses plankton to

Rennet (pron.: /ˈrɛnɨt/) is a complex of enzymes produced in any mammalian stomach‚ and is often used in the production of cheese. Rennet contains many enzymes‚ including a proteolytic enzyme (protease) that coagulates the milk‚ causing it to separate into solids (curds) and liquid (whey). They are also very important in the stomach of young mammals as they digest their mothers ’ milk. The active enzyme in rennet is called chymosin or rennin (EC 3.4.23.4) but there are also other important enzymes
