Answer 1

1. True. The liver and kidneys are the major sites of Gluconeogenesis.

Gluconeogenesis occurs in animals during starvation or other wasting conditions like Diabetes mellitus, when the organism necessarily requires glucose as a source of energy. It meets the needs of the body for glucose when carbohydrate is not available in required amount from the diet. The principal site is the liver, being responsible for 85%-95% of glucose formation. Gluconeogenesis also occurs in the cortex of kidney, but the amount formed here is small.
