### process | reaction:

Anabolic reaction
* give off energy.
* require energy input.
* use up energy.

Assertive reaction
* allow people to stand up for themselves.
* involve verbal and nonverbal messages.
* promote positive mental health and healthy relationships.
* reduce stress by allowing people to take steps to resolve the feelings.

Autoimmune reaction
* Some autoimmune reaction leads to brain damage
* are unfortunate mistakes of the immune system.
* contribute to many enigmatic diseases.

Biochemical reaction
* Most biochemical reactions involve solutes dissolved in water
  - occur in the watery, or aqueous, phase
  - take place in liquid environments
* Some biochemical reaction involves enzymes
  - several enzymes
  - produces light
* are chemical reactions that take place inside the of living things.
* do have thresholds according to kinetic theory.
* go fast at higher temps.
* require enzymes to speed up and control reaction rates.
* take place inside the cells.

Bioluminescent reaction
* All bioluminescent reactions occur in the presence of oxygen.
* Most bioluminescent reactions involve luciferin and luciferase.

### process | reaction:

Cheletropic reaction
* are a subclass of cycloadditions.
* confirm the conservation of molecular orbital symmetry
  * are a subclass of cycloadditions. What sets cheletropic reactions apart is that on one of the reagents, both new bonds are being made to the same atom. A few examples are shown to the right in Figure 1. In the first case, the single atom is the carbon atom in the carbonyl group. That carbon atom ends up in carbon monoxide. The end result is making two new bonds to one atom
+ Cheletropic reaction, Theoretical analysis: Pericyclic reactions
  * Because of the geometry of the molecules involved in cheletropic reactions, they confirm a number of predictions made by theoretical chemists. Cheletropic reactions confirm the conservation of molecular orbital symmetry.

Combination reaction
* are always exothermic.
* occur when two separate reactants are bonded together, e.g.

Decomposition reaction
* Most decomposition reactions are endothermic.
* are always endothermic.
* is reaction

Dependent reaction
* Most dependent reaction produces oxygen.
* Some dependent reaction occurs in membranes.
* requires energy.

Different reaction
* have different equilibriums.
* release energy in different ways.

Dyotropic reaction
* are important in organic chemistry.
* can be a useful step in making large and complicated molecules
  * are important in organic chemistry. They can explain how certain reactions work. Dyotropic reactions can be a useful step in making large and complicated molecules. Dyotropic reactions were first described by Manfred T. Reetz in 1971.'Dyotropic Rearrangements, a New Class of Orbital-Symmetry Controlled Reactions'

Electrochemical reaction
* are chemical reactions in which electrons are transferred.
* cause neurons to fire.
* determine hydrogen pickup in underwater wet welds.
* occur on the surface of an electrode.
* produce an electric current in a manner similar to a battery.

Electrocyclic reaction
* occur frequently in nature.
+ Electrocyclic reaction, Electrocyclic reactions in biological systems: Chemistry
  * Electrocyclic reactions occur frequently in nature. Biosynthetic and Biomimetic Electrocyclizations. One of the most common such reactions in nature is the biosynthesis of vitamin D3.

Enzymatic reaction
* Many enzymatic reactions are complex and involve more than one substrate
* require particular pHs.

Fission reaction
* Most fission reaction creates heat
  - involves splits
* Some fission reaction produces fission products
* are reactions where larger elements are broken into smaller elements.
* result in formation of lighter atoms.
