What are the 5 protein groups
Structural proteins, hormones, antibodies, receptors, enzymes
What are proteins made of?
Amino acids.
What makes proteins diffrent
they are diffrent because they are in diffrent sequences of amino acids.
What does the amino acid decide
The amino acid sequence determines both the structure and function of the protein.
What do some proteins have
Some proteins have a structural function, they give strength and support to cellular structures including membranes, muscles, ligaments, and tendons.
What does collegen do
Collagen helps support the skin, muscles and tendons.
What do enzymes do
Enzymes are proteins that speed up biochemical reactions like digestion, respiration and photosynthesis.
What is amylase
Amylase is an enzyme that breaks down starch in the digestive system.
What do hormones do
Hormones are proteins that act as ‘chemical messengers’. They are involved in regulating processes like growth and metabolism.
What is insulin
