Explanation

Pepsin is a type of enzyme.

Correct sentence: Pepsin is an enzyme used in digestion.

پیپسن ایک انزائم ہے جو عمل انہضام میں استعمال ہوتا ہے۔

Explanation

Most proteins are made up of 20 different amino acids.

These 20 amino acids are commonly referred to as the standard or proteinogenic amino acids.

While other amino acids exist, they are not typically found in the primary structure of proteins that make up most living organisms.

Explanation

A peptide is a molecule composed of two or more amino acids linked together through amide bonds.

It is a polyamide, meaning it is a polymer of amino acids.

Peptides are smaller than proteins, which are long chains of amino acids.

Explanation

Amino acids are the building blocks of proteins, which are long chains of amino acids linked together by peptide bonds.

There are 20 different amino acids that the human body uses to build proteins.

They are essential for various cellular processes, including structure, function, and regulation.

Explanation

Seafood is an excellent source of protein because it is typically low in fats (lipids) and high in protein.

Many types of seafood, such as fish and shellfish, are lean sources of protein, making them a popular choice for those looking to reduce their fat intake.

Explanation

In the human body, there are more than 1,000 known enzymes.

These enzymes play essential roles in catalyzing biochemical reactions.

Explanation

• Pepsin is a proteolytic enzyme produced by the chief cells in the stomach lining.
• It breaks down proteins into smaller peptides and amino acids, initiating protein digestion in the acidic environment of the stomach.

Explanation

Kwashiorkor is a condition caused by a deficiency of dietary protein, leading to an imbalance in the gastro-intestinal system. It is characterized by:

• Edema (swelling) in the legs, feet, and face
• Diarrhea
• Weight loss
• Hair loss
• Skin lesions
• Impaired immune function
