Hint:

{Thyroxin → Controls metabolism and growth.
{Insulin → Regulates blood sugar level.

Answer 1

Concept: Hormones are chemical substances produced by endocrine glands that regulate various functions in the body. Two important hormones are thyroxin and insulin, which help control metabolism and blood sugar levels.
Step 1:Role of Thyroxin Thyroxin is a hormone secreted by the thyroid gland. It plays an important role in regulating the metabolism of carbohydrates, proteins, and fats in the body. Functions of thyroxin:

• Regulates the metabolic rate of the body.
• Helps in growth and development.
• Controls the use of energy in cells.

A deficiency of thyroxin can cause diseases such as goitre.
Step 2:Role of Insulin Insulin is a hormone produced by the pancreas. It helps regulate the amount of glucose (sugar) in the blood. Functions of insulin:

• Controls the blood glucose level.
• Helps cells absorb glucose from the blood.
• Converts excess glucose into glycogen for storage in the liver and muscles.

A deficiency of insulin can lead to diabetes mellitus.
