They are termed to be metabolic pathways.
Enzymes serve to speed up reactions by lowering the energy of activation
Enzymes lower the activation energy for chemical reactions, allowing the reactions to proceed. Enzymes also can serve to bring components of a reaction together in the proper orientation. Enzymes can hydrolyze macromolecules into smaller components, enabling them to be transported across the cell membrane. Without enzymes, many metabolic reactions would not be able to be conducted efficiently, if at all.
how do cells regulate synthesis to conserve energy
Reactions that absorb energy from the environment are referred as endothermic reactions.
These are not chemical reactions but thermonuclear reactions.

The light reactions provide energy carriers for the dark reactions.
Endothermic reactions require energy while exothermic reactions release energy.
Reactions that absorb energy from the environment are referred as endothermic reactions.
Exothermic reactions release energy.
endothermic reactions require energy
If by energy you mean heat energy exothermic reactions.
Chemical reactions that release energy often occur spontaneously. Chemical reactions that absorb energy will not occur without energy.
