Proteins/ Enzymes Flashcards
Reactants
The elements or compounds enter in a chemical reaction
Chemical reaction
A process that changes or transforms one set of chemicals to the other.
Products
The elements or compounds produced by a chemical reaction
Catalyst
A substance that speeds up the rate of a chemical reaction
Function of enzymes
Substrates
Reactants of the enzyme-catalyzed reactions
Proteins
Large polymers composed of amino acids and do most of the cells work
Examples of proteins
Hormones and enzymes
How do enzymes change?
The temperature or Ph can effect the shape (function) of the enzymes
Enzymes
A type of protein that speeds up chemical reactions (catalysts or catalase)
A type of protein is an enzyme
Structural proteins
Mussel
Keratin
Collagen
Elements of proteins
C,H,O,N,(S)
Carbon, hydrogen, oxygen, nitrogen, and sometimes sulfur
Substrate and enzymes
Enzymes are made for specific elements or compounds
Lock and key
Other types of proteins
Lactase- breaks down milk or dairy (lactose intolerant)
Insulin- regulates sugar amount (type of hormone) *diabetes
Collagen- make up skin (sun harms collagen)
Examples of enzymes
Salivary amylose
Catalysts-> catalase
What shape are proteins?
3D shape and the amino acids fold in a certain way that determine the protein’s function
