Question

Mark argues that proteins within the body have two functions: structure and transport. Sara disagrees. Which significant function of proteins did Mark omit from his list?

Answer 1

Answer:

important function of protien: they are body building food.

Answer 2

Required Answer:

Mark told that proteins inside our body are meant for structure and transport. His statement is true but incomplete. Proteins are organic molecules which were made up of amino acids bonded with peptide bonds.

If we see Mark statement, then it is true✓ in the sense:

• Proteins helps in strengthening and forming the structural framework of the body. Like they are found in the bones, tendons, ligaments, skin etc.

• They also carry vital substances throughout the body like haemoglobin is a protein that helps in the transport of O2 in blood$.$

Now, Sara disagrees for a reason. Because she knows that proteins have other functions also like:

• They act and form enzymes and proteins which helps in regulating biological reactions.

• They also protect the body from foreign substances and germs by forming antibodies.

• They also help in the contractile system. Like Myosin and actin helps in movement.

• They help in storage also. They store protein in milk and egg white.
