The nitrogen base tri-phosphates (like ATP, GTP etc) and NADPH produced during the Light reaction provide the energy for the Dark reaction.
When a reaction has products that have a lower temperature than the reactants did, the reaction is endothermic.
The products of the reaction will have less energy than the reactants
Have sufficient energy to exceed the "activation energy" for the reaction.
Energy coupling
Activation energy
These substances are called reactants, the reaction produces products. This type of reaction is called exothermic. As in the following reaction with the burning of methane: CH4 +2O2 ---> CO2 + 2H2O (reactants) (products)
In an exothermic reaction the energy of the products is less than that of the reactants.
When a reaction has products that have a lower temperature than the reactants did, the reaction is endothermic.
The products of the reaction will have less energy than the reactants
Propane is burned to provide the heat in many cooking grills. The chemical reaction for this process is shown in the equation below. C3H8 + 5O2 ? 3 CO2 + 4H2O + energy What are the products in this chemical reaction? 3CO2 + 4H2O + energy
CO2 + 2H2O + energy
Kinetic energy has more energy than products.
NADPH and ATP
reactants and products and bond energy creates a chemical reaction
A chemical reaction whose reactants have less potential energy than the products would be called an endothermic reaction.
Have sufficient energy to exceed the "activation energy" for the reaction.
