Flashcards in Biological Functions of Proteins Deck (13)
The functions of proteins are divided into three categories, name these categories
Physiologically active proteins
What is meant by the structural function of proteins?
These are used to build parts of the body
What is meant by the physiologically active functions of proteins
These assist with the normal functioning of the body
What is meant by the nutrient functions of proteins?
These play a nutritional role within the body
List the structural functions of proteins
Production of cell membranes, muscle issue and skin
Cell repair and replacement
List the physiologically active functions of proteins
Production of hormonal proteins
Production of enzymes
Production of antibodies
Production of blood proteins
Production of nucleoproteins
What are hormonal proteins?
This help to coordinate bodily activities such as the production of insulin
What are enzymes?
These speed up chemical reactions such as pepsin which speeds up the breakdown of proteins in food
What are antibodies?
These defend the body from harmful substances such as viruses
What are blood proteins
These move molecules around the body such as haemoglobin which transports oxygen through the blood
What are nucleoproteins
These make up the heredity material in chromosomes
List the nutrient functions of proteins
Provide the body with essential amino acids
Excess can be used as a source of energy when carbohydrate and fat reserves are used
