Chemical Reactions
Potential Energy
stored energy as a result of its position condition or composition a child climbing up a slide. -The energy stored in a chemical bond, like a covalent bond. This type of potential energy is called chemical energy
Chemical Reaction
A process during which chemical bonds between atoms are broken and new ones are formed. Producing one or more different substances.
Catalyst
A substance which speeds up a chemical reaction without being used up in the reaction
Chemical Equilibrium
Chemical Equilibrium
Products
Ending materials in a chemical reaction.
Ending materials in a chemical reaction.
Energy needed to get a reaction started
Define catalyst and describe how a catalyst affects a reaction rate.
Enzyme combines with reactant, substrate, forming enzyme-substrate complex and then product is released
Explain how organisms use chemical reactions to capture and release energy and to make new compounds and break down compounds.
In a living cell, chemical reactions are carried out to store chemical energy by forming bonds or to release energy by breaking them. -Your body digests carbohydrates, lipids, and proteins in food. Chemical energy is released when covalent bonds in these molecules are broken. -Your cells are building molecules like fats, nucleic acids, and proteins. The covalent bonds that form to build these molecules store chemical energy
Example of Kinetic Energy
Kinetic energy convert to potential energy - example: plants take the light energy from the sun to build sugars and other molecules locking in potential energy.
Example of Potential Energy
Potential energy convert to kinetic energy - example: coal has lots of energy burning coil releases kinetic energy and allows us to run our power plants.
Write a simple chemical reaction using proper chemical notation (Note: See "Rules of Chemical Notation posted on the Biology Department website, www.austincc.edu/biology)
Process by which atoms or groups of atoms are reorganized into different substances
Emzymes
Proteins that help to speed up chemical reactions.
Products
Represent molecules that are made by the reaction
Reactants
Represent molecules that are the starting material for the reaction
Substrates
The reactant molecules the bind the enzymes active site
volume
are which molecules move
Kinetic Energy
energy associated with motion or doing work child sliding down a slide.
Concentration
number of molecule.
