Document Summary
In exergonic reactions, energy release occurs as the (cid:396)ea(cid:272)ta(cid:374)t (cid:862)flo(cid:449)s do(cid:449)(cid:374)hill(cid:863) some energy to the endergonic process: equation: (cid:2163)= (cid:2164) (cid:2176) (cid:2175) Forms of energy: chemical (fossil fuel and oil burner, mechanical (hydroelectric generating plant, heat (solar panel forms, light (sun, electrical, nuclear (reactor, photosynthesis and respiration represent the most fundamental examples of energy. Examples of energy conversions conversion in living cells: photosynthesis. Biologic work in humans: mechanical work of muscle action, chemical work that synthesizes cellular molecules such as glycogen, triacylglycerol, and protein, transport work, that concentrates substances such as sodium and potassium ions in the intracellular and extracellular fluids. In the cell nucleus, contractile elements literally tug at chromosomes to facilitate cell division. Chemical work: biosynthesis of cellular molecules, all cells perform chemical work for maintenance and growth, continuous synthesis of cellular components takes places as other components degrade. Hydrolysis and condensation: the basis for digestion and synthesis.
