They occur in the mitochondria, a type of organelle located in the cytoplasm.
FalseAll chemical reactions require an initial input of energy called activation energy.
Chemical reactions that release energy often occur spontaneously. Chemical reactions that absorb energy will not occur without energy.
Generally, the energy required to initiate the reaction. Reactions that release energy (exothermic) can proceed faster than those that require energy to be added (usually in the form of heat energy).
yes it does Glucose stores chemical energy in a concentrated, stable form.

glucose
Chemical energy via the sugar molecule Glucose.

In the light reactions of photosynthesis, energy from sunlight becomes stored as chemical energy in the bonds of organic products. These products are glucose, a kind of sugar.
Energy is from glucose.
These are not chemical reactions but thermonuclear reactions.
Heat energy is necessary for some chemical reactions to occur. Some chemical reactions are endothermic meaning they require or absorb energy for a chemical reaction to occur. Other chemical reaction are exothermic meaning they release energy when the chemical reaction takes place..
"Activation Energy reactions"; Endothermic reactions require energy.
Chemical reactions that release energy often occur spontaneously. Chemical reactions that absorb energy will not occur without energy.
