Describe two types of postural defects. Explain the Biuret test for proteins, the end product of protein digestion, and four functions of proteins. List four other classes of food.

Let's tackle these questions. 6. Two types of postural defects are: • Scoliosis: A sideways curvature of the spine. • Kyphosis: An excessive outward curve of the spine, causing a hunchback. 7. This question was answered previously, but here it is again for clarity: a) The Biuret test turning purple indicates the presence of proteins. The class of the food item is: Proteins b) During digestion, proteins are broken down into their simplest units. The end product of protein digestion is: Amino acids c) Proteins play several vital roles in the body. Four ways proteins are important to an individual are: • They are essential for the growth and repair of body tissues. • They are used to produce enzymes and hormones, which regulate body processes. • They form antibodies that help the body fight infections and maintain immunity. • They can serve as an energy source when carbohydrates and fats are insufficient. d) Besides proteins, there are several other essential classes of food. Four other classes of food are: • Carbohydrates • Fats (or Lipids) • Vitamins • Minerals Last free one today — make it count tomorrow, or type /upgrade for unlimited.
