Enzymes and Cell Theory Flashcards
(15 cards)
Enzyme
A protein that catalyzes chemical reactions
Catalase
An enzyme
Chemical Reaction
A process that changes or transforms one set of compounds into another
Reactants
The elements or compounds that engage in a chemical reaction
Products
The elements or compounds produced by a chemical reaction
Chemical reaction that releases energy…
Occur on their own
Chemical reaction that absorbs energy….
Require a source of energy
Most enzymes are…
proteins
Enzymes reduce
the activation energy
Active Site
where the substrate bonds to the enzyme
Enzymes are ____ and ____
specific and resusable
What denatures enzymes
Extreme heat and acids
Enzyme substrate complex
Enzymes are specific because the 3d shape of the active site corresponds directly with the 3d shape of a substrate like a lock and key model
3 parts of cell theory
1) All life is made up of cells
2) Cells are the smallest unit of life
3) All cells come from pre-existing cells
Scientific Theory
