Silica gel is a granular, vitreous, porous form of silicon dioxide made synthetically from sodium silicate. Silica gel is tough and hard; it is more solid than common household gels like gelatin or agar.It is a naturally occurring mineral that is purified and processed into either granular or beaded form.n this form, it is used as a desiccant to control local humidity to avoid spoilage or degradation of some goods. Because silica gel can have added chemical indicators (see below) and adsorbs moisture very well, silica gel packets usually bear warnings for the user not to eat the contents.
Cellular respiration is the set of metabolic reactions and processes that take place in the cells of organisms to convert biochemical energy from nutrients into adenosine triphosphate (ATP), and then release waste products.lthough technically, cellular respiration is a combustion reaction, it clearly does not resemble one when it occurs in a living cell due to slow release of energy from the series of reactions.
Through cellular respiration the cells harvest energy stored in food by a catabolic pathway for the production of adenosine triphosphate (ATP). ATP is a high energy molecule which is spent by working cells. Cellular respiration takes place both in eukaryotic and prokaryotic cells. Cellular respiration can be aerobic respiration in the presence of oxygen or anaerobic respiration in the absence of oxygen. There are two types of cellular respiration: Aerobic and Anaerobic respiration. Aerobic Respiration. Aerobic respiration takes place in the presence of oxygen, by which ATP is is produced by the cells by oxidation of organic compounds.
