Vocabulary for the Biology Keystones (2013)
Terms in this set (30)
A nonliving factor of an ecosystem
The minimum energy required to initiate (start) a specific chemical reaction.
The movement of particles from an area of low concentration to high concentration that uses energy from ATP or a difference in electrical charges across a cell membrane
Adenosine Triphosphate (ATP)
A molecule that provides energy for a cellular reaction and process. It releases energy when one of its high-energy bonds is broken to release a phosphate group
Intermolecular attraction between unlike molecules. (water sticking to glass)
Artificial cultivation of food, fiber, and other goods by the systematic growing and harvesting of various organisms. Related to farming
A variation of a gene's nucleotide sequence (Alternative form of a Gene)
The measure of the relative frequency of an allele at a genus locus in a population.
A physical structure, present in multiple species, that is similar in function, but different in form and inheritance (Bat wing and butterfly wing)
A term that describes an organism associated with a water environment
The smallest unit of an element that retains the chemical and physical properties of that element
The changing of organic matter into other chemical form such as fuel
The study of energy flow (energy transformations) into and within living systems
The movement of abiotic factors between the living and nonliving components within ecosystems; aka nutrient cycles (ie Water Cycle, Carbon Cycle, Nitrogen Cycle)
A group of Biomacromolecules that interact with biological systems and their environments (lipids, carbohydrates and proteins)
The scientific study of life
A large area or geographical region with distinct plants and animals adapted to that environment (Tundra)
The zone of life on Earth, the total sum of all ecosystems on Earth
Any procedure or methodology that uses biological systems or living organisms to develop or modify either products or processes for specific use.
A term that describes a living or once-living organism in an ecosystem
A macromolecule that contains the atoms of carbon, hydrogen and oxygen in a 1:2:1 ratio and serves as a major source of energy for living organisms (eg sugars, starches, cellulose)
Carrier (Transport) Proteins
Proteins embedded in the plasma membrane involved in the movements of ions, small molecules and macromolecules into and out of cells
The number of individuals in a population that can be supported in an ecosystem given the resources available and other environmental pressures.
A substance that enables a chemical reaction to proceed at a usually faster rate or under different condition (e.g lower temperatures) than other wise without being changed by the reaction (Enzymes are examples)
The basic unit of structure or function for all living organisms.
The series of events that take place in a cell leading to its division and duplication. The main phases are interphase, nuclear division and cytokinesis
A complex set of chemical reactions involving an energy transformation where potential chemical energy in the bonds of "food" molecules is released and partially captured in the bonds of adenosine triphosphate
An organelle found in plant cells and the cells of other eukaryotic photosynthetic organisms where photosynthesis occurs
A change in the structure of a chromosome
(eg deletion, duplication, Inversion, and translocation, )
A single piece of coiled DNA and associated proteins found in the nucleus of eukaryotic cells and circular forms in the cytoplasm of prokaryotic cells; contains genes that encode traits. Each species has a characteristic number.
