What process synthesizes glucose from noncarbohydrate precursors such as glycerol or certain amino acids?

Noncarbohydrate precursors of glucose are first converted into pyruvate or enter the pathway at later intermediates such as oxaloacetate and dihydroxyacetone phosphate . The major noncarbohydrate precursors are lactate, amino acids, and glycerol.

relative humidity, temperature and dew point -- are bound together in the mathematical relationship below. relative humidity changes when temperatures change. because warm air can hold more water vapor than cool air, relative humidity falls when the temperature rises if no moisture is added to the air. so i would say a
