Week+4


 * 1) __Biochemical Conversion__** - The changing of organic matter into other chemical forms such as fuels.


 * 2) __Bioenergetics__** - The study of energy flow (energy transformations) into and within living systems.


 * 3) __Biogeochemical Cycles__ ** - The movement of abiotic factors between the living and nonliving components within ecosystems; also known as nutrient cycles (i.e., water cycle, carbon cycle, oxygen cycle, and nitrogen cycle).


 * 4) __Biological Macromolecules__** - A group of biomacromolecules that interact with biological systems and their environments.


 * 5) __Biology__** - The scientific study of life.


 * 6) __Biome__** - A large area or geographical region with distinct plant and animal groups adapted to that environment.


 * 7) __Biosphere__** - The zone of life on Earth; sum total of all ecosystems on Earth.


 * 8) __Biotechnology__** - Any procedure or methodology that uses biological systems or living organisms to develop or modify either products or processes for specific use. This term is commonly associated with genetic engineering, which is one of many applications.


 * 9) __Biotic__** - A term that describes a living or once‐living organism in an ecosystem.


 * 10) __Carbohydrate__** - A macromolecule that contains atoms of carbon, hydrogen, and oxygen in a 1:2:1 ratio and serves as a major source of energy for living organisms (e.g., sugars, starches, and cellulose).


 * 11) __Carrier (Transport) Proteins__** - Proteins embedded in the plasma membrane involved in the movement of ions, small molecules, and macromolecules into and out of cells; also known as transport proteins.
