Which of the following substances is excreted by the sweat glands in response to the breakdown of proteins and the formation of ammonia?

Rationale

Urea is the substance excreted by the sweat glands in response to the breakdown of proteins and the formation of ammonia.

Urea is a waste product formed in the liver following the breakdown of proteins. The liver converts ammonia, a toxic byproduct of protein metabolism, into urea. Urea is then expelled from the body through sweat and urine.

A (Lysozymes) YOUR ANSWER

Lysozymes are not excreted in response to protein breakdown or ammonia formation. They are enzymes that destroy bacterial cell walls, and are found in various body fluids, including tears and saliva, to provide immunity.

B (Water) YOUR ANSWER

While water is a major component of sweat, it is not specifically excreted in response to protein breakdown and the formation of ammonia. Instead, water is released by sweat glands to help regulate body temperature.

C (Urea) CORRECT

Urea is the correct answer. It is a waste product formed in the liver from the breakdown of proteins. The liver transforms ammonia, a toxic byproduct of protein metabolism, into urea. Urea is then expelled from the body through sweat and urine.

D (Sebum) YOUR ANSWER

Sebum is not excreted in response to protein breakdown or the formation of ammonia. It is an oily substance produced by the sebaceous glands to lubricate the skin and hair.

Conclusion

Among the given choices, urea is the only substance that is excreted by the sweat glands in response to the breakdown of proteins and the formation of ammonia. This process is essential for the elimination of waste products from the body. Other options like lysozymes, water, and sebum serve different roles in the body and are not directly linked to protein metabolism or ammonia formation.

Which of the following substances is excreted by the sweat glands in response to the breakdown of proteins and the formation of ammonia?

Urea is the substance excreted by the sweat glands in response to the breakdown of proteins and the formation of ammonia.
