Activation energy describes the energy that is required to get chemical reactions started.
These are not chemical reactions but thermonuclear reactions.
Chemical energy
The light dependent reactions take in the light energy and convert that to chemical energy, but it is in the Calvin cycle (light independent reactions) where the chemical energy is stored in a complex sugar.
energy needs to be added to a molecular system to start the proccess

endothermic reaction
Breaking bonds requires energy.
no, some reactions are spontenous.
It is released from the cracker by the chemical bonds breaking up.
transfer of energy from one form to another.
"Activation Energy reactions"; Endothermic reactions require energy.
These are not chemical reactions but thermonuclear reactions.
Chemical reactions that release energy often occur spontaneously. Chemical reactions that absorb energy will not occur without energy.
