Casein is protein which form the part of food for the young animal. Best source of casein is milk.

The anhydrobonds of protein are called peptide bonds. A peptide bond is formed between carboxyl group of one amino acid and amino group of adjacent.

Since proteins form components of cytoplasm, therefore it is responsible for growth and repair.

Collagen is the most abundant extracellular protein which with ageing becomes less permeable, less flexible and insoluble. These changes interfere the normal functioning of the cells (decreased inflow of nutritive substances and oxygen into cells and also decreased loss of nitrogenous waste and $CO _{2}$ from the body cells) and induce ageing.

Proteins are the primary structural components of cells and tissues, often referred to as body-building foods because they are essential for growth and repair.

A moderately active man typically requires approximately 2500 to 3000 kcal per day. 3160 kcal is the most realistic value among the choices provided.

Rennin is an enzyme secreted in the stomach that acts on the milk protein caseinogen and converts it into insoluble paracasein, which is subsequently precipitated by calcium ions to form curd. This is a key step in infant milk digestion.

Enterokinase is the enzyme that activates trypsinogen into trypsin. Without trypsin, other pancreatic proteases cannot be activated, making protein digestion in the duodenum impossible.

Hemoglobin acts as a weak acid in the blood, often represented as HHb (protonated hemoglobin) when it binds to hydrogen ions, functioning as a buffer.

Chylomicrons are lipoprotein particles that consist of triglycerides, phospholipids, cholesterol, and proteins. They transport dietary lipids from the intestines to other locations in the body.
