Biology Terms Essay

Absorption- The process by which the products of digestion are transferred into the body’s internal environment, enabling them to reach the cells. Adenosine troposphere (TAP) A common form in which energy is stored in living systems; consists of a nucleotide (with ribose sugar) with three phosphate groups. The energy coin of the cell. Aerobic -relating to or denoting exercise that improves or is intended to improve the efficiency of the body’s cardiovascular system in absorbing and transporting oxygen. Anaerobic- Refers to organisms that are not dependent on oxygen for respiration.

Authoress- Organisms that synthesize their own nutrients; include some bacteria that are able to synthesize organic molecules from simpler inorganic compounds. Cells – The smallest structural units of living matter capable of functioning independently. Chemisorbs- The process by which TAP is produced in the inner membrane of a mitochondria. The electron transport system transfers protons from the inner compartment to the outer; as the protons flow back to the inner compartment, the energy of their movement is used to add phosphate to ADAPT

Electromagnetic spectrum :the entire range of wavelengths or frequencies of electromagnetic radiation extending from gamma rays to the longest radio waves and including visible light. Eukaryote- A type of cell found in many organisms including single-celled protests and multicultural fungi, plants, and animals; characterized by a membrane-bounded nucleus and other membranous organelles; an organism composed of such cells. The first eukaryote are encountered in rocks approximately 1. 2-1. Billion years old. Homeostasis – The ability to maintain a relatively constant internal environment. Hormones- Chemical substances that are produced in the endocrine glands and travel in the blood to target organs where they elicit a response. Light reactions- The photosynthetic process in which solar energy is reversed and transferred into the chemical bonds of TAP; can occur only in light. Membrane-a pliable sheet like structure acting as a boundary, lining, or partition in an organism. Gyroscope -an optical instrument used for viewing very small objects

Reactant- a substance that takes part in and undergoes change during a reaction. Ultraviolet -(of electromagnetic radiation) having a wavelength shorter than that of the violet end of the visible spectrum but longer than that of X-rays. Vacuole -a space or vesicle within the cytoplasm of a cell, enclosed by a membrane and typically containing fluid. Water vapor- or water vapor or aqueous vapor, is the gaseous phase of water. Wavelength -the distance between successive crests of a wave, especially points in a sound wave or electromagnetic wave.
