What are the key functions of proteins?

Answer 1

respiration, reproduction, response.

respiration: circulation of nutrients to its designated area

reproduction: make more cells.

response: to external stimuli. if its cold the cell will get warm. if its hungry itll go find food

Answer 2

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 functions of proteins.

Answer 3

proteins have all of the amino acids necessary to build and repair cells. Proteins are the only food source that is capable of building and repairing cells.
