Question

Proteins in the living cells act as
(A) Enzymes
(B) Hormones
(C) Antibodies
(D) All

Answer 1

Proteins in the living cells act as (D) Enzymes, Hormones, Antibodies, All.

Proteins:

• Numerous thousands of amino acids, which are smaller building blocks of proteins, are linked together in long chains to form proteins.
• To create a protein, 20 distinct kinds of amino acids can be mixed.
• An incredibly complex, naturally occurring molecule known as a protein is made up of amino acid residues connected by peptide bonds.
• All living things contain proteins, which are the building blocks of numerous vital biological substances like enzymes, hormones, and antibodies.
• Protein molecules can be divided into two categories: globular proteins and fibrous proteins. The majority of globular proteins are spherical, soluble, and compact.
• The majority of fibrous proteins are elongated and insoluble.
• One or more of the four forms of protein structure may be present in globular and fibrous proteins.

Answer 2

Answer:

Proteins in the living cells act as enzymes, Hormones, Antibodies

Explanation:

Proteins have unique shapes and molecular weights; a few proteins are globular in form while others are fibrous in nature. For example, hemoglobin is a globular protein, however, collagen, located in our skin, is a fibrous protein. Protein form is important to its function, and this form is maintained via way of means of many unique sorts of chemical bonds.

Enzymes:

• Enzymes, which might be produced via way of means of dwelling cells, are catalysts in biochemical reactions (like digestion) and are normally complicated or conjugated proteins. Each enzyme is precise for the substrate (a reactant that binds to an enzyme) it acts on.
• The enzyme might also additionally assist in the breakdown, rearrangement, or synthesis reactions. Enzymes that damage their substrates are known as catabolic enzymes, enzymes that construct extra complicated molecules from their substrates are known as anabolic enzymes, and enzymes that have an effect on the price of response are known as catalytic enzymes.

Hormones

• Hormones are chemical-signaling molecules, normally small proteins or steroids, secreted via way of means of endocrine cells that act to manipulate or alter precise physiological processes, together with growth, development, metabolism, and reproduction.
• For example, insulin is a protein hormone that allows altering the blood glucose level.

Antibodies

• Antibodies are proteins that defend you whilst an undesirable substance enters your body. Produced via way of means of your immune system, antibodies bind to those undesirable materials that allow you to put off them out of your system. Another phrase for the antibody is immunoglobulin.
