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.
