Question

Read the following statements:
1. Thymosins are peptide hormones
2. Parathormone leads to hypercalemia
3. $\alpha$- cells are most abundant in islets of langerhans
4.Insulin mainly acts upon adipoytes and hepatocytes
How many statements are incorrect?

• A. None
• B. One
• C. Two
• D. Three

Answer 1

The correct option is A None

1. Thymosins are a group of small peptides with molecular weights of 1000–15,000Da. Thymosins are isolated from the thymus gland.

2. Hypercalcemia is caused by increased levels of parathyroid hormone (PTH). It raises the blood calcium level by taking the calcium out of your bones.

3. Islets of Langerhans are micro-organs in the pancreas that contains the α- and β-cells. They are the most abundant ones in the Islets of Langerhans and are important for glucose homeostasis.

4. Insulin is a peptide hormone that helps in the regulation of glucose homeostasis. It mainly acts on hepatocytes and adipocytes and enhances the cellular glucose uptake and utilization.

So, all the options are correct.
