Proteins And Enzymes Flashcards
What are enzymes?
Biological catalysts
What is the function of receptors?
Allow cells to recognise specific substances
Examples of receptors?
Liver cells have receptors for insulin
What is the function of antibodies?
They provide specific defence against body invaders such as certain bacteria and viruses
Examples of antibodies?
Immunoglobulins give specific defence against invading influenza viruses
What is the function of hormones?
To carry specific messages in the bloodstream of living organisms
Examples for hormones
Insulin signals to the mammal liver to store excess glucose
What is the function of enzymes?
To act as a biological catalyst to speed up chemical reactions
Example for enzymes?
Amylase speeds up the breakdown of starch molecules in animal digestive systems
What is the function of structural units?
The give strength and support to cellular structures
Example for structural units?
Membrane proteins give membranes their shape and strength
