    Carbohydrates have two major functions in plants and animals: they serve as fuel and building material. Plants store most of their energy in the form of starch. Starch is a polysaccharide (consisting of several conjoined sugars). Synthesizing starch enables the plant to stockpile surplus glucose, and since glucose is a major cellular fuel, starch represents stored energy. The sugar can later be withdrawn by hydrolysis, which breaks the bonds between monomers. Animals, in turn, have enzymes that…

    Homeostasis What is it? Maintenance of a relatively constant internal environment The human body is constantly responding to internal and external factors in order to maintain relative stability within the body Homeostasis is vital to the body as a whole, right down to each individual cell. If homeostasis is not maintained at the cellular level this will affect the body as a whole. History Claude Bernard (1813-1878): consistency of internal environment is the condition for free life.…

    Intro: Carbohydrate, any of a large group of compounds in which hydrogen and oxygen, in the proportions in which they exist in water, are combined with carbon; the formula of most of these compounds may be expressed as Cn(H2O)n. Structurally, however, these compounds are not hydrates of carbon, as the formula would seem to indicate. Carbohydrates, as a class, are the most abundant organic compounds found in nature. They are produced by green plants and by bacteria using the process known as photosynthesis…
