Answer 1

1. Protein is one of the essential nutrients needed by human body to build and repair tissues,.It has diverse set of fuctions in body. Proteins are classified as complete and incomplete proteins. Complete proteins are the sources containing nine essential amino acids which cannot be synthesized by the body.

• It contain all 20 amino acids: When a protein source has nine essential amino acids it is said to be complete protein. All the remaining amino acids care synthesized in body.
• It is completely digestible: It takes around 1.5 hours to digest and they are not completely digested .
• It contain all essential amino acids:Nine amino acids cannot be synthesized by the body which are to be gained from external protein source.When a supplement with those nine essential amino acid is termed as a complete protein.(Answer)
• It completely satisfies all nutrition needs: A balanced diet needs carbohydrates, proteins, fats ,vitamins and minerals to satisfy the nutrition needs . So it is wrong

2. Chemical group present in every amino acid are  amine (-NH₂) and carboxyl (-COOH) functional groups. The general structural formula of aminoacid is ( -NH₂CHRCOOH).

• Benzyl group: Benzyl is the substituent or molecular fragment with the structure C₆H₅CH₂– and commonly used in organic synthesis as a strong protecting group for alcohols and carboxylic acids .Not present in aminoacid
• aldehyde group:Aldehyde is an organic compound containing a functional group with the structure −CHO and present in most fragrances.Not present in amino acid
• Peroxide group:Peroxide group  contain oxygen–oxygen single bond or the peroxide anion, so it is not present in amino acids.
• Carboxyl group: Amino acids are organic compounds found to contain two functional groups one amine and carboxyl group.Aminoacids are the building blocks of protein.(Answer)

3. Consequences of excess protein intake leads to weight gain , constipation because of low fibers, dehydration as body excretes excess nitrogen(present in amino acids) with fluids and water, excess nitrogen found in the amino acids damage kidneys,etc

• Improved renal functioning : Protein intake destroys kidney
• Increased production and excretion of urea: Body may be producing high amounts of urea, a by product of protein metabolism.(Answer)
• Increased protein storage by kidneys:Excess intake poses burden on excretion in kidneys
• Decreased excretion of calcium:Calciuria is present in protein excess intake individuals leading to bone problems

5. Proteins play a central role in biological processes.

Fuel for body : Carbohydrates provide energy , and they are called fuel for body

Building blocks of body: Proteins are called building blocks as they are required for the structure, function, and regulation of the body's tissues and organs(Answer)
