Question

Which one of the following is the reason for increased hair loss during old age?
A. Reduction of blood supply
B. Decrease in protein synthesis
C. Low energy production.
D. None of the above.

Answer 1

The pattern baldness is found only in man and it is inherited and dominated in a male if the ancestor carries baldness character. Male pattern baldness increases during old age due to lack of blood supply that leads to reduced formation of hair follicles.

Complete answer:
Male pattern baldness is occurring not only in the reduction of blood supply but also due to dihydro-testosterone formation in males, which is a variant of testosterone. That dihydro-testosterone compound accumulates in the hair follicle of the scalp, which leads to a reduction of blood supply in a hair follicle that decreases in nutrition uptake, which is necessary for the formation of hairs. The male pattern baldness is also known as androgenic alopecia. Females also suffer pattern baldness due to low blood level, nutrition level, and stress which cause female baldness.
B. Decrease in protein synthesis:- Protein is the essential macromolecule which is made up of different amino acids in a specific order that makes it functional. Protein is formed by a translation process that takes place in the cell cytoplasm or outside the nucleus. Protein is the main building block of the tissue or body and enzyme also made up of protein. If protein formation decreases in the body so that leads to retardation of growth and development of the body.
C. Low energy production:- It is said to be low ATP production which leads to low blood sugar which makes the organism ill and fatigue. Which is not good for your health. Energy production takes place by converting food into glucose and that glucose stored in the liver by pancreatic enzyme and utilizing stored glucose when blood sugar decreases.
Hence, the correct option is A.

Note: Male pattern baldness does not only occur due to old age or low blood supply but also occurs due to low intake of nutrients in the diet which is required for the formation of hair such as vitamin-E, biotin, low protein diet. Baldness may cure by therapy or massaging with oil or hair transplant.
