If a patient lacks intrinsic factor production in their stomach, which consequence affecting digestive processes is most likely?

A)Increased protein digestion efficiency
B)Enhanced carbohydrate absorption rate
C)Reduced vitamin B12 absorption efficiency
D)Elevated bile acid recycling capacity

💡 Explanation

Reduced vitamin B12 absorption results when intrinsic factor is absent because this glycoprotein is essential for B12 uptake in the ileum. B12 forms a complex with intrinsic factor, therefore without it, absorption decreases significantly, rather than affecting other processes like protein digestion or bile acid recycling.
