If you read these sections with a knowing eye, you’ll realize that everything discussed as happening during starvation happens during carbohydrate restriction as well. There have been a few papers published recently showing the same thing: the metabolism of carb restriction = the metabolism of ...
During prolonged fasting or the onset of starvation, proteins will eventually be used for energy. Explain how this state of inadequate intake shifts protein/amino acid metabolism. How is enzyme activity regulated by the cell? What is the process where proteins lose their structure?
The UPS is the primary selective proteolytic system in mammalian cells, regulating numerous biological processes such as development, gene transcription, signal transduction, metabolism, apoptosis, cell cycle, DNA repair and inflammation (Chen et al.2008; Melino2005; Wang and Maldonado2006; Yao and N...

sugars. For example, the activity of phosphofructokinase 1 (PFK1), a key enzyme in the glycolysis pathway, is suppressed byO-GlcNAcylated at serine (Ser)529, resulting in the redirection of glucose metabolism through pentose phosphate pathway (PPP), thus increasing nucleotide metabolism [95]....
