Step 1
(i) Red blood cell formation; essential for synthesis of DNA and RNA; development of brain.
Answer
Folic acid plays a crucial role in red blood cell formation and is essential for the synthesis of both DNA and RNA. This function is vital for overall cellular health and is particularly important during periods of rapid growth, such as during pregnancy. Additionally, folic acid contributes to brain development.
Step 2
(ii) spinal cord and skeleton in foetus; reduces risk of neural tube defects e.g. spina bifida;
Answer
Folic acid is essential in the early stages of fetal development, especially for the formation of the spinal cord and skeleton. Adequate folic acid intake significantly reduces the risk of neural tube defects, such as spina bifida, which can have serious implications for the health of the infant.
Step 3
(iii) may play a role in preventing heart attacks, strokes and cancer; etc.
Answer
Research suggests that folic acid may help to prevent cardiovascular diseases, such as heart attacks and strokes, by reducing homocysteine levels in the blood. Additionally, there is evidence that folic acid may have protective effects against certain types of cancer, contributing to overall health.
