Select all of the following that are true about the absorption, digestion and balance of Vitamin B12. Lack of B12 also triggers a deficiency of Niacin. Taking antacids like Prilosec and Nexium will help in B12 absorption. Elderly may not make enough intrinsic factor to absorb B12. Toxicity from taking high dose supplementation is common. It can be stored in the liver so doesn't need to be supplemented daily. Even small deficiencies can be associated with lower scores on intelligence tests, lowered spacial abilities and decreased short term memory. Deficiencies are associated with anemia and nerve damage. Deficiency is common in those with a vegan diet.

6. TRUE or FALSE: a. ________Several vitamins such as vitamin B6, niacin (B3), riboflavin (B2), and pantothenic acid (B5) are components of coenzymes that are required by enzymes involved in the synthesis of heme, an important group on hemoglobin, the O2 carrier in the blood. b. ________Vitamin B12 is unique among the water soluble vitamins because it is must be bound to a protein in the stomach called intrinsic factor in order to be absorbed, it is found naturally only in animal foods, and it can be stored in significant quantities in the liver 7. Explain how calcium and vitamin D work together for calcium maintenance. Include all organs involved and their functions in this process.
