Starvation early stages

When food intake decreases, the utilization of fat and protein reserves in the body enables various essential metabolic processes to continue during the nutritional inadequacy. In the early stage of fasting or starvation, glucose requirements of the brain and nervous system are fulfilled by mobilization of glycogen in the liver. This short-term adaptation lasts only a day until glycogen stores are exhausted. Gluconeogenesis... 

Which one of the following products of protein metabolism is decreased below normal levels during the early stages of starvation ... 

The chick embryo can be cultuered in vitro at a relatively early stage of development and is nutritionally responsive. For studies of protein starvation with these embryos, a medium was sought which would... 

In the early stage of starvation, noradrenahne and cortisol induce breakdown of protein. Generation of KBs from FAs takes place in the Hver, while glycerol and amino acids are used for gluconeogenesis. In starvation, uric acid excretion falls by about 50 per cent. Liver glycogen is exhausted after 12—24 hours without food. 

Which is the most dramatic difference between metabolic states observed in the early and prolonged starvation stages ... 

D. discoideum shows reliable chemotaxis to cAMP at the early development stage, after 5-h starvation. These cells are typically used for chemotaxis analysis. This section describes the method for preparing the cells.
