Proteins And Enzymes Flashcards
What is a gene?
A specific sequence of bases within DNA that holds the information to build proteins.
Genome?
Contains all of the genetic information about an organism.
Gene expression
The decoding of genes to make proteins.
Proteins are large molecules known as…
Polymers. They are made up of many amino acids.
Polypeptide?
Amino acids joined by peptide bonds.
Amino acids cause polypeptide chain to twist so sections are side by side and hydrogen bonds are formed.
Two types of proteins:
Fibrous and globular
What functions do fibrous proteins have?
Mechanical functions like support and protection
What function do globular proteins have and name one…
They have chemical functions in the body, a globular protein is an enzyme. They lower activation energy
What binds to an enzymes active site?
A substrate
Induced fit
Enzyme is flexible and moulds to fit substrate perfectly, forming the enzyme-substrate complex.
How do enzymes speed up a reaction?
They provide an alternate reaction pathway with a lower activation energy.
