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.
How Cellular Respiration Works. The process of cellular respiration occurs in four stages: glycolysis; the transition stage; the Krebs cycle, also known as the citric acid cycle; and the electron transport chain. Each stage accomplishes different tasks. Glucose is the primary fuel used in glycolysis, the first stage of cellular respiration.
