BI110 Lecture Notes - Lecture 2: Electromagnetic Spectrum, Adenosine Triphosphate, Adenosine
Document Summary
Adenosine triphosphate -> phosphate removed -> nrg released for cell metabolism = adenosine. Diphosphate -> nrg from nutrients = phosphate added -> adenosine triphosphate. The theory of evolution is the cornerstone of modern scientific understanding of life. Evolution occurs in two different scales: microscales and macro scales. Geographic isolation where the environment of two populations is different and over long time scales, the genetic diversity that existed results in two distinct species (macro) Macro(longer time scales and ends with two different species) Concept of evolution was originally proposed by darwin. Evolution requires genetic diversit in population and environmental conditions that promote fitness of certain individuals. The sun converts matter into nrg (electromagnetic radiation) Can take on forms such as electromagnetic radiation (visible/uv light), chemical and kinetic nrg. Radio waves are the longest wavelengths and have the least amount of nrg. High energy wavelengths such as gamma rays and x-rays have the shortest wavelength.
