What are the function of proteins?

Answer 1

membrane transport,cell recognition,metabolism,structure

Proteins have many functions. They serve as enzymatic catalysts, are used as transport molecules (hemoglobin transports oxygen) and storage molecules (iron is stored in the liver as a complex with the protein ferritin); they are used in movement (proteins are the major component of muscles); they are needed for mechanical support (skin and bone contain collagen-a fibrous protein); they mediate cell responses (rhodopsin is a protein in the eye which is used for vision); antibody proteins are needed for immune protection; control of growth and cell differentiation uses proteins (hormones). These are just a few examples of the many, many functions of proteins.
some proteins control the rate of reactions and regulate cell processes.

Answer 2

There are many functions of proteins. They are the basic building blocks of living things and are responsible for the growth and repair of body cells and tissues. The human body is about one half muscle, and muscles are mostly made of proteins.

Some of the main functions carried out by proteins include:

• Structural Support : Proteins make up the hair, nails, muscles etc.
• Hormones: Many hormones are protein in nature; hormones control growth and metabolic activities of the body.
• Enzymes: Enzymes are globular protein. Enzymes speed up the biochemical reactions and help in digestion.
• Hemoglobin: A protein called hemoglobin contains iron atom that temporarily links with oxygen and releases it throughout the body.
• Blood Clotting: Fibrinogen is a glycoprotein which helps in healing of wounds. Thus it prevents the blood loss and inhibits the passage of germs.
• Antibodies: Antibodies are proteins that bind to the pathogens and inhibit their activities.

Protein functions different at different location Eg.In Enzymes - protein is main part for conversion of reactant into product It fuctions as energy sourse For stability of genetic material in eukryotics
Proteins are organic molecules that form muscles, transport O2 (hemoglobin), and act as hormones and enzymes. Proteins are used for growth and repair.

They are essential to organisms, and maintaining a good supply of them is necessary otherwise damaged cells won't be repaired and nor will anything grow.
They help build and maintain body cells and tissues.

Answer 3

The Function of Protein is to build the body and to repair the body.........!!!!!!!!

• Structural Support : Proteins make up the hair, nails, muscles etc
• Hormones: Many hormones are protein in nature; hormones control growth and metabolic activities of the body.

• Blood Clotting: Fibrinogen is a glycoprotein which helps in healing of wounds. Thus it prevents the blood loss and inhibits the passage of germs.
• Antibodies: Antibodies are proteins that bind to the pathogens and inhibit their activities.

Answer 4

Proteins have various functions in the body, including acting as enzymes to catalyze chemical reactions, serving as structural components in cells and tissues, aiding in the transport of molecules, playing a role in immune response, and serving as hormones to regulate bodily processes.

Answer 5

what are the function of proteins

Proteins are the building blocks of the body in an organism.
