Answer 23

HbA2 (2 alpha, 2 delta chains)

Question 24

What is the normal sequence of B12 absorption?

Answer 24

1. dietary B12 binds to salivary haptocorrin
2. haptocorrin B12 complex is broken down by pancreatic proteases
3. Free B12 binds to IF, which is secreted by gastric parietal cells
4. B12-IF complex is absorbed by ileal mucosal epithelial cells
5. B12 is transported in blood bound to transcobalamin
