Chemical reactions

The process of changing one set of chemicals into another set of chemicals

Reactants

Chemicals that enter the reaction

Product

Chemicals that are formed or produced as a result of the reaction

more

In an energy-absorbing reaction, the products have ______ energy than the reactants.

less

In an energy-releasing reaction, the products have ______ energy than the reactants.

heat, light, sound, motion

Energy can be released as _____________________. (Four Options, Separate each by Comma)

Photosynthesis

The process of absorbing light energy and storing it as glucose

Cellular Respiration

The breakdown of glucose into ATP

Activiation Energy

The energy needed to get a reaction started

Catalyst

Substance that speeds up a chemical reaction by lowering activation energy. Does not affect substance

Enzymes

Proteins that speed up virtually every important reaction that takes place in cells. Can be catalysts

1

substrates

Enzymes and __________ fit together like a lock and key. Very Specific shapes

-ase

Enzymes end with the letters _____ (Use hypen)

reactants

Substrates are the _________ of enzyme-catalyzed reactions.

active site
