What increases in fetal tissues due to accelerated development of pancreas islets in a diabetic mother?

In the context of a diabetic mother, the accelerated development of the pancreas islets in the fetus signals an increase in insulin production. This increase in insulin levels plays a crucial role in promoting the storage of fat and glycogen within fetal tissues. Insulin acts as an anabolic hormone, facilitating the uptake of glucose that can subsequently be stored as glycogen, particularly in the liver and muscle tissues. Additionally, insulin promotes the conversion of excess glucose into fatty acids, leading to increased fat storage, which can contribute to macrosomia (an excessively large fetus) in the case of gestational diabetes. Consequently, the correct answer highlights the notable impact of elevated insulin levels on fat and glycogen storage in the developing fetus of a diabetic mother.
