Which of the following is a possible function of a protein?

Long-term energy storage

Insulating organisms

Sending signals across the organism

Answer 1

i will go with Long term energy storage

Answer 2

@chandhuru m i right?

Answer 3

proteins are used as signaling molecules in the form of hormone so option D is correct

Answer 4

@mysha your answer is right but mostly proteins are used as energy use under extreme conditions so i think sending signals across the organism is more appropriate...

Answer 5

@chandhuru yea D is correct :D

Answer 6

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.
