Ch.8 Notes Date Notes Questions 10/12/15 To types of metabolic pathways Catabolic pathways (breaking down, breaking down energy) Anabolic pathways (storing energy, build up) Pathways can be complex and have multiple steps Pathways are the chemical reactions Ex pathways a->b->c-> (a, b and c are chemicals) Living organisms are chemical computers Design like circuit boards Some people working on DNA based computer Also there are works on neuro networks Organisms always share chemicals with everyone Prokaryotes have a much simpler pathways than eukaryotes Metabolic theory that there is a mathematical formula that can explain the interaction of organisms. Energy cannot be created or destroyed Sunlight->Glucose->ATP->Heat Glucose more desired because easiest way to get ATP

Cellular Respiration Cellular respiration can be described as a chemical process that breaks bonds in food molecules or transforms chemical energy from organic molecules into ATP. - Only 40% of food energy is extracted and used for cellular work where the other 60% leaves in the form of heat energy ATP= Provides chemical energy for cellular work/processes in the cell. Structure= Composed of complex organic molecule called adenosine with a tail of three phosphate groups and a ribose sugar- pentose (ADP+P=ATP) (ADP is a diphosphate with an adenosine) ATP is recycled from ADP and phosphate through cellular respiration, ADP and P are connected to create ATP to be used for cell processes, ATP is used for cellular work and ADP and P are extracted from food molecules to create ATP again.

Chapter 8 An Introduction to Metabolism Overview: The Energy of Life the living cell is a miniature factory where thousands of chemical reactions occur energy is converted in many ways some organisms convert energy into light ? bioluminescence Concept 8.1: An organisms metabolism transforms matter and energy, subject to the laws of thermodynamics metabolism is the totality of an organism?s chemical reactions, consisting of catabolic and anabolic pathways an emergent property arising from the interaction of molecules Organization of the Chemistry of Life into Metabolic Pathways a metabolic pathway is a series of chemical reactions that either builds a complex molecule (anabolic pathway) or breaks down a complex molecule into simpler compounds (catabolic pathway)
