Document Summary
G3p forms the basic building block for more complex carb molecules (ch2o) Carbs exist as monosaccharide or chains of monosaccharide. Most commonly 3, 5 or 6 carbon molecules. Monosaccharide with 5 or more carbons can fold into a ring form o. Ring form more common than linear in cells. Used for a number of cellular funcions aside from energy storage. Catabolic, exergonic pathway which consumes oxygen and produces water. Energy extracted from glucose to a form that the cell can readily use - atp. Electrons which are farther from the nucleus contain more energy. Electrons that share c-h bonds are equidistant from both atomic nuclei o. Energy release with electrons transferred to oxygen (oxidaion) Energy is lost as heat and unavailable to do work. Controlled - small steps with low acivaion energy. Opportunity to transfer food energy to other molecules o o. Also binds electrons and h+ on nitrogenous base nicoinamide.
