Homeostasis:
In biology, homeostasis is the state of steady internal, physical, and chemical conditions maintained by living systems. This is the condition of optimal functioning for the organism and includes many variables, such as body temperature and fluid balance, being kept within certain pre-set limits.
Explanation:
Amino acids are the building blocks of proteins. Proteins are digested in the gastrointestinal tract into peptides,polypeptides and single amino acids using hydrochloric acid and proteases. After protein digestion amino acids are absorbed by the jejunum in the small intestines and taken up by capillaries to the blood stream. They then travel in the blood to the liver, joins the urea cycle where they are metabolised for cell growth and tissue repairs.
The factors which determine the shape of protein are;
1. Order of amino acids.
2. The number of amino acids which are used.
The order of amino acids or in other words primary structure determines how folding of amino acid chain or its tertiary structure.
Protein is termed as the chemicals which are found in all cells which are used for growth and work. Protein in the human body includes hemoglobin and collagen.
