Document Summary
Biology 1202b: lecture 8 cellular respiration i. G3p forms basic building block for more complex carbohydrate molecule (ch2o) Carbohydrates exist as monosaccharides or chains of monosaccharides: most commonly 3, 5, or 6 carbon molecules. Monosaccharides with 5 or more carbons can fold into a ring form: ring form more common than linear in cells. Used for a number of cellular functions aside from energy storage. Catabolic, exergonic pathway which consumes osygen and produces water. Energy extracted from glucose to a form that the cell can readily use atp. Glucose + 6o2 6co2 + 6h2o + energy. Electrons which are farther from the nucleus contain more energy. Electrons that share c-h bonds are equidistant from both atomic nuclei: high energy, can easily be removed to do work. Uncontrolled: energy release with electrons transferred to oxygen, energy release is uncontrolled, energy is lost as heat and unavailable to do work, g = -686 kcal/mol.
