- Ecology
- Study of the interrelationships of organisms and their environment.
- Ecosystem
- A community of organisms interacting with each other and with their nonliving surroundings.

- Endotherm
- An animal that maintains its body temperature with heat generated by its metabolism.
- Energy
- Capacity for doing work. [free energy]
- Enhancer
- Region of DNA that stimulates the initiation of the transcription of a gene. Enhancers differ from promoters in being farther away from, and either upstream (5') or downstream (3') of, the gene they influence. [Discussion]
- Enkephalins.

- Enzymes
- [ Enzyme Kinetics ]
- Eotaxin
- Epicotyl
- That portion of the shoot of a plant embryo or seedling above the node at which the cotyledons are attached. [View]

- Eugenics
- The application of genetics in an attempt to "improve" the hereditary qualities of humans.
- Euglenozoa
- Eukaryote
- An organism whose cells contain a membrane-bound nucleus. Sometimes spelled eucaryote.
- Euryarchaeota

- Excitatory postsynaptic potential (EPSP)
- Excretion
- Elimination of metabolic wastes by an organism. [in humans]
- Exocrine
- Refers to glands that deposit their secretion(s) into ducts that drain to the "exterior". Examples: salivary, sweat, and gastric glands [View topology]. Compare endocrine
- Exocytosis
- Exon
- Portion of a gene that is retained in the messenger RNA (mRNA) molecule.Adjacent exons are separated from each other by introns. Often exons encode one domain of a protein. The ability to shuffle exons in different combinations may - over the course of evolution - have speeded up the creation of new genes with new functions. [More]
