A vapor bubble rises in a liquid. The relevant dimensionalparameters are the liquid specific weight, , the vapor specificweight, , bubble velocity, V, bubble diameter, d, surface tension,, and liquid viscosity, . Find appropriate dimensionlessparameters.
How Cells Release Chemical Energy (Respiration) All organisms have to acquire energy: photoautrophs get E (ATP) from the sun heterotrophs get E (ATP) from eating plants and one another ATP - E of the cell - produced during cellular respiration using the mitochondria - the circulatory system diffuses O a2d C H O6to12he6mitochondria for processing ATP is given off along with CO and H 2 2 - cellular respiration consists of many steps mediated by specific enzymes - high E e’ are removed from glucose breakdown and passed down an E.T.C. to a lower E level - as e’ move from one carrier to the next, E is released and recaptured for ATP production - chemical E (glucose) is transferred into usable E, but some E is lost as heat st nd (1 and 2 Laws of Thermodynamics) - as you exercise, E is produced resulting in a rise in body temperature – sweat cools the body (evaporation, vaporatization) Cellular Respiration C H O + 6 O 6 CO + 6 H O 6 12 6 2 2 2 = a cellular process that requires O a2d gives off CO and 2 O plus2E - opposite of photosynthesis, but don’t forget that plants also use cellular respiration to breakdown sugar to release E glucose = high E carbon dioxide = low E water = low E - when glucose is broken down, E is released (exergonic)
