The energy in glucose is transformed into ATP. What energy transformations occur between glucose and ATP? Photosynthesis involves both light reactions and dark reactions. Where do they occur? What are the products? Plants make ATP during the light reactions of photosynthesis. Why do plants also nee...
Such rearrangements can occur when cells dissimilate nutrients. The phosphate group involved in the high-energy phosphate bond then can be transferred directly to ADP, forming ATP, which now contains the high-energy phosphate bond. (Note that bond energy is the energy required to break a bond, ...
Media representations can be seen to occur through the so-called “framing’’, which Entman (1993, p. 52) defines as selecting some aspects of a perceived reality and emphasizing them to promote a particular interpretation, evaluation, or solution to a problem. Frames are words, phrases, or...
according to the level of difficulty of addressing them. level one challenges require deploying established technologies that face the least physical hurdles. level two challenges require deploying known technologies to accelerate and scale them. level three challenges occur when technological performan...
Thus, arises one of the fundamental principles of thermodynamics—the interconvertibility of energy forms as well as the “trade-offs” between the intensity and capacity factors. All forms of energy are interconvertible; when conversions do occur, they do so according to rigorous laws of exchange...
Concentration polarization does not occur when the membrane separates solutions with the same concentrations ( C h k = C l k ). Therefore, the hydraulic fluxes are identical, J v r = J v , for both homogenous and concentration polarization conditions at least for Δ P of ~105 Pa. Thus,...

How do you encourage engagement? How do you create the conditions that enable collaboration and cooperation to occur? How can we combine all the forces that make up the Energy Transition? In the past week or so, I have gained a growing belief we are building the momentum to bring the diff...
Inefficiencies occur due to the large number of energy transformations, and battery life is limited by the number of charge and discharge cycles, an effect made worse when current levels are high. A flywheel is proposed as a superior alternative to the battery which can provide power levels as...
Geothermal energyis the energy contained in the Earth׳s interior. The origin of this energy is linked with the internal structure of our planet and the corresponding complex physical processes that still occur in it. Practical uses of geothermal energy, for bathing, washing and cooking, date ...
