Chapter 8- The Metabolism Flashcards
Cellular respiration
Drives this cellular economy by extracting energy stored in sugars and other fuels
Bioluminescent
Stored energy in certain molecules to light
Metabolism
Totality of an organisms chemical reactions
Metabolic pathway
Starts with a starting molecule an goes through a series of steps resulting in a product
Catabolic pathways
Breakdown pathways which releases energy by doing this and into simpler compounds (cellular respiration)
Anabolic Pathways
Consumes energy to build complicated molecules from simpler ones, they are sometimes called biosynthetic pathways. Example is the synthesis of amino acids from simpler molecules and the synthesis of protein from amino acids
Bioenergetics
Study of how energy flows from living organisms
Energy
Capacity to cause change
What does the work of life depend on
Ability of cells to transform energy from one form to another
Kinetic energy
Energy of motion
Thermal energy
Connecticut energy associated with the random movement of atoms or molecules
Heat
Thermal energy and transferred from one object to another
Is light a type of energy
Yes that can be harnessed for formwork such as powering the photosynthesis and green plants
Potential energy
Energy that matter possesses because of its location or structure
Chemical energy
Potential energy available for release in a chemical reaction
During a catabolic reaction do bonds break or form
Both, releasing energy and resulting in lower energy breakdown products
Biochemical pathway
Enable cells to release chemical energy from food molecules and use the energy to power life processes
Thermodynamics
Study of the energy transformation that occurs in a collection of matter
Is the difference between open and close system
Open system is when energy and matter can be transformed between the system and its surroundings unlike an isolated system
