This glossary of biology terms is a list of definitions of fundamental terms and concepts used in biology, the study of life and of living organisms.It is intended as introductory material for novices; for more specific and technical definitions from sub-disciplines and related fields, see Glossary of cell biology, Glossary of genetics, Glossary of evolutionary biology, Glossary of ecology ...
The gross anatomy of a muscle is the most important indicator of its role in the body. One particularly important aspect of gross anatomy of muscles is pennation or lack thereof. In most muscles, all the fibers are oriented in the same direction, running in a line from the origin to the insertion.
In biology, a substrate is the surface on which an organism (such as a plant, fungus, or animal) lives.A substrate can include biotic or abiotic materials and animals. For example, encrusting algae that lives on a rock (its substrate) can be itself a substrate for an animal that lives on top of the algae.
A soil type or a lichen substrate rock type that is rich in or largely composed of calcium carbonate. calceolate Shaped like a slipper. [25] calcicole A plant which thrives in calcareous soil. Also calciphile, calciphyte. Antonym: calcifuge. [25] callose Hardened; thickened; callous. callus. pl. calli. 1. A protruding mass of tissue 2.
Standard anatomical terms of location are used to describe unambiguously the anatomy of animals, including humans. The terms, typically derived from Latin or Greek roots, describe something in its standard anatomical position. This position provides a definition of what is at the front ("anterior"), behind ("posterior") and so on.
Substrate presentation; A substrate (purple rectangle) is shown sequestered into a lipid domain (green lipids). The substrate's translocation to the disordered region (grey lipids) presents it to its enzyme (blue oval) where it is hydrolyzed. In molecular biology, substrate presentation is a biological process that activates a protein.
Substrate (building), natural stone, masonry surface, ceramic and porcelain tiles; Substrate (chemistry), the reactant which is consumed during a catalytic or enzymatic reaction; Substrate (materials science), the material on which a process is conducted; Substrate (printing), the base material that images will be printed onto
[1]: 26 In most cases of a metabolic pathway, the product of one enzyme acts as the substrate for the next. However, side products are considered waste and removed from the cell. [2] Different metabolic pathways function in the position within a eukaryotic cell and the significance of the pathway in the given compartment of the cell. [3]
