called nucleotides. Each nucleotide contains a phosphate group, a sugar group and a nitrogen base. The four types of nitrogen bases are adenine (A), thymine (T), guanine (G) and cytosine (C). The order of these bases is what determines its instructions, or genetic code<\/a><\/p>\n\n\n\n<p><a>DNA replication<\/a><\/p>\n\n\n\n<p><a>process of copying DNA molecules<\/a><\/p>\n\n\n\n<figure class=\"wp-block-image\"><img decoding=\"async\" src=\"https:\/\/quizlet.com\/cdn-cgi\/image\/f=auto,fit=cover,h=200,onerror=redirect,w=240\/https:\/\/o.quizlet.com\/Vlrli2QGrleyArCMct7keQ.jpg\" alt=\"Image: DNA replication\"\/><\/figure>\n\n\n\n<p><a>cell cycle<\/a><\/p>\n\n\n\n<p><a>sequence of events from the production of a eukaryotic cell to the time the cell itself reproduces<\/a><\/p>\n\n\n\n<figure class=\"wp-block-image\"><img decoding=\"async\" src=\"https:\/\/quizlet.com\/cdn-cgi\/image\/f=auto,fit=cover,h=200,onerror=redirect,w=240\/https:\/\/o.quizlet.com\/MCqG-por8WCuFtWc2y4E7g.png\" alt=\"Image: cell cycle\"\/><\/figure>\n\n\n\n<p><a>transcription<\/a><\/p>\n\n\n\n<p><a>the process by which DNA is copied to RNA<\/a><\/p>\n\n\n\n<figure class=\"wp-block-image\"><img decoding=\"async\" src=\"https:\/\/quizlet.com\/cdn-cgi\/image\/f=auto,fit=cover,h=200,onerror=redirect,w=240\/https:\/\/o.quizlet.com\/1KnGLfKU4V-WxEJy0ujfvQ.png\" alt=\"Image: transcription\"\/><\/figure>\n\n\n\n<p><a>translation<\/a><\/p>\n\n\n\n<p><a>RNA is used to produce proteins<\/a><\/p>\n\n\n\n<figure class=\"wp-block-image\"><img decoding=\"async\" src=\"https:\/\/quizlet.com\/cdn-cgi\/image\/f=auto,fit=cover,h=200,onerror=redirect,w=240\/https:\/\/o.quizlet.com\/4r5oendElx.-9uJzXOzQLA.png\" alt=\"Image: translation\"\/><\/figure>\n\n\n\n<p><a>aerobic pathway<\/a><\/p>\n\n\n\n<p><a>process of producing cellular energy involving oxygen<br><br>occurs in the mitochondria of the cell and is used for activities requiring sustained energy production<\/a><\/p>\n\n\n\n<p><a>anaerobic glycolysis<\/a><\/p>\n\n\n\n<p><a>breakdown of glucose that occurs in the absence of oxygen<\/a><\/p>\n\n\n\n<p><a>cellular respiration<\/a><\/p>\n\n\n\n<p><a>set of metabolic reactions and processes that take place in the cells of organisms to convert biochemical energy from nutrients into adenosine triphosphate (ATP), and then release waste products. &#8230; Respiration is one of the key ways a cell releases chemical energy to fuel cellular activity<\/a><\/p>\n\n\n\n<p><a>glycolysis, krebs cycle, electron transport<\/a><\/p>\n\n\n\n<p><a>3 major steps of aerobic respiration<\/a><\/p>\n\n\n\n<p><a>glycolysis<\/a><\/p>\n\n\n\n<p><a>breakdown of glucose to pyruvic acid<\/a><\/p>\n\n\n\n<p><a>Krebs cycle<\/a><\/p>\n\n\n\n<p><a>the sequence of reactions by which most living cells generate energy during the process of aerobic respiration.
