the energy that drives the light independent reactions comes from

Counting carbons—keeping track of where the carbon atoms go in each reaction—is a simple way to help understand what is happening in the Calvin cycle. {\displaystyle W} Noether's theorem has become a fundamental tool of modern theoretical physics and the calculus of variations. where In the electromagnetic spectrum, the type of radiation that we call visible light occurs between _____. The figure shows the absorption spectrum for chlorophyll a and the action spectrum for photosynthesis. The speed of a chemical reaction (at given temperature T) is related to the activation energy E by the Boltzmann's population factor e−E/kT – that is the probability of molecule to have energy greater than or equal to E at the given temperature T. This exponential dependence of a reaction rate on temperature is known as the Arrhenius equation. , is sometimes ignored, especially when the thermal efficiency of the transfer is high. The region of ATP synthase that catalyzes the production of ATP from ADP and inorganic phosphate spans the chloroplast membrane. × For an activity that must be sustained for an hour, output drops to around 300; for an activity kept up all day, 150 watts is about the maximum. where the first term on the right is the heat transferred into the system, expressed in terms of temperature T and entropy S (in which entropy increases and the change dS is positive when the system is heated), and the last term on the right hand side is identified as work done on the system, where pressure is P and volume V (the negative sign results since compression of the system requires work to be done on it and so the volume change, dV, is negative when work is done on the system). This is called equipartition principle; total energy of a system with many degrees of freedom is equally split among all available degrees of freedom. One of the important waste products of photosynthesis is oxygen gas. Early investigators thought the oxygen produced by photosynthetic plants came from carbon dioxide. Life: 1788–1860. In quantum mechanics energy is expressed using the Hamiltonian operator. In processes where heat is generated, quantum states of lower energy, present as possible excitations in fields between atoms, act as a reservoir for part of the energy, from which it cannot be recovered, in order to be converted with 100% efficiency into other forms of energy. This thermal energy drives plate tectonics and may lift mountains, via orogenesis. The most famous of them used the "Joule apparatus": a descending weight, attached to a string, caused rotation of a paddle immersed in water, practically insulated from heat transfer. In its mechanism, photophosphorylation is most similar to _____. [note 3] Simpler organisms can achieve higher energy efficiencies than more complex ones, but the complex organisms can occupy ecological niches that are not available to their simpler brethren. *In this experiment, Engelmann was able to determine which wavelengths (colors) of light are most effective at driving photosynthesis. t The light reactions of photosynthesis use _____ and produce _____.
