### process | reaction:

Fusion reaction
* All fusion reactions involving elements lighter than carbon are exothermic.
* Many fusion reactions release large amounts of energy.
* Most fusion reaction creates electromagnetic energy
* Some fusion reaction occurs at cores.
* Some fusion reaction releases energy
  - heat energy
  - reactions are easier to produce than others
* are another way they generate energy.
* are the combining of two nuclei to form a more massive nucleus
  - heat source in the core of the sun
* create much of the energy given off by the sun.
* involve the fusion of light nuclei, which results in a release of nuclear energy.
* produce more power than fission
  - the energy radiation of stars, among others of the sun
* release enormous amounts of energy.
* require input of energy to cause the initial fusing event
  - that the atoms be raised to temperatures of millions of degrees
* supply the power needed for our sun to shine.

Human reaction
* Most human reactions resulting from fly bites are initial pain, local irritation and swelling.
* vary from extreme susceptibility to near immunity.

Hydrolysis
* decreases the degree of polymerization of polysaccharides.
* is reaction

Incompatible reaction
* cause the pollen tube to stop growing on or near the stigma.
* result in localized cell death and the formation of a barrage zone.

Light reaction
* Most light reaction is part of photosynthesis.
* convert solar energy into chemical energy.
  - photochemical reaction
* is the capture of light energy in the chloroplast of plant cells
  - first photosynthesis stage which requires light
* occur in the thylakoids of chloroplasts
  - mostly in the thylakoid stacks of the grana
* take place on the actual thylakoid membrane.
* takes place in association with the thylakoids.

Metabolic reaction
* All metabolic reactions are either catabolic or anabolic.
* Many metabolic reactions require water as a reactant.
* Most metabolic reaction induces development.
* Some metabolic reaction produces heat.
* occur in arranged sequences called pathways
* take place in the cytoplasm or at the plasma membrane.

Mild reaction
* are quite common to childhood immunizations.
* causes symptoms.

Molecular reaction
* are virtually responsible for every cellular process.
* cascades in olfactory signal transduction.

Neutralization reaction
* give off heat.
* is reaction

Precipitation reaction
* are also widely used in industry
  - dependent on the presence of multivalent antibodies and antigens
  - one type of double-replacement reaction
  - useful in quantitative analysis
* occur widely in nature.

Rapid reaction
* involves oxygen.
* produces copper and hydrogen.

### process | reaction:

Reflex
* Most reflexes have responses.
* Some reflexes have a combination of nervous and endocrine response.
* are a form of instinct
  - type of instinct
  - actions that serve to protect and stabilize the human body
  - automatic, unconscious responses to a certain stimuli
  - bodily functions that require no input from the brain
  - essentially an involuntary motor response to a sensory stimulus
  - fast, unconscious muscular reactions that occur due to unexpected physical stimuli
  - pre-programmed stereotypical responses to specific sensory stimulation
  - reactions of relatively simple nervous mechanisms
  - simple, stereotyped motor responses to a stimulus
  - specific, predictable, involuntary responses to a particular type of stimulation
  - the newborn's most obvious organized patterns of behavior
  - very important to a dog's everyday life
* automatically take over forcing air back into the lungs.
* reflect the muscles and roots levels from which they are derived.
* represent the simplest forms of behavior.
