Question

a) Compare glycolitic pathway with;
1) aerobic glycolysis in blood stream trypanosomes.
2) hydrogenosomal pathway in trichomonads.

b) explain hormone receptors and their abnormalities.
c) describe disorders of parathyroid glands.

Answer 1

B). Hormone receptors - Receptor protein present on surface of cell or in its interior that binds to specific hormone. This binding leads to signal transduction pathway or, activation or inhibition of genes is triggered. Two types of hormone receptors are present - 1. Peptide hormone receptors or cell surface  

2. Intracellular or nuclear receptors or steroid or hormone receptors

Examples are - 1. Thyroid receptor defects

2. Growth hormone receptor defect

3. Glucocorticoid receptor defect

4. Vasopressin receptor defects

5. Insulin receptor defect

6. Androgen receptor defect

7. Parathyroid receptor defect
