Explain the energy transformation that occurs when a person exercises. How does the electron transport chain transfers the energy from high-energy electron carriers to ATP? Explain. a) What happens in a chemical reaction? b) What does activation energy (E_A) mean?
For example, Kα radiation occurs when a vacancy in the K-shell is filled by an electron from the L-shell (CuKα energies are 8.047 and 8.027 keV) and Kβ is an electron from the M-shell filling a vacancy in the K-shell (CuKβ energies are 8.903, 8.973, and 8.970 keV). The ...
Congestion occurs when too much electricity transits over the network, leading to over-heating of cables and the risk of fire. Several factors may explain this circumstance: a network that has been well-dimensioned early on or the small share of intermittent RE in the current power mix. This ...
This occurs, for example, when the energy security priority is rebalanced in relation to environmental sustainability. This process might also involve layering policy instruments when novel policy instruments in support of greater sustainability will be introduced in parallel to maintain the priority of ...

This occurs after uptake by other countries drives down prices further. Fig. 2: Renewable share of electricity. a total renewables (hydro + wind + solar + biomass) and (b) solar PV. Initially, renewables are dominated by hydropower and to a lesser extent wind. This is soon overtaken by ...
As most individual energy use occurs in homes, and energy-related decisions impact the entire household, we use the term household also when referring to individuals (as residents and consumers rather than, e.g., as politicians or experts). In transitions research, household agency refers to ...
result of ATP hydrolysis, the protons are released into the channel, while ADP and Pi are transported back through F1to the aqueous phase. However, in the synthesis of ATP, protons are picked up from the proton channel by phosphate, and phosphorylation of ADP occurs in the active center of...
produces a reaction force acting on the rotor. Steam is directed to the rotor by the fixed blades of the stator. The steam then changes its direction, and its velocity increases relative to the rotation speed of the blades. The pressure drop occurs both in the stator and the rotor blades....
The required activated energy for adsorption significantly differs from that required for desorption process, which could be related to the dimensional changes of the solid ammoniates as the ammoniate expands when adsorption occurs and it contracts when desorption occurs, and extra activation is required...
