1) Alternative Pobrown-fat cells in brow the alternative fat cells are based upon so called cycle. for futile these, ATP is used to phosphorylated protein oo energetically feed a process, and then the protein is dephosphorylated or the process is passively reversed. 2) Where such process care potential ther mogenic, the main problem is brown and britel Leigo Cells in the low amount of ATP syothave found is there cells, thus, even if Guch proc. eas used all synthesred ATP for thermogenesis, they coomd only be able to utilize eufout 10% of the respiratory chain Capaity - and this would not be enough to replace shivering y The triglyceride Justice trigitle & de cycle, where and then ATP down to Latty acid i lo are broken used to recootbyssize triglyceride classic suggestion but This is basically a very no evilance for an adaptive recruitment, for exemple has been presented. 7 A smooth endoplasmic reticulum co²t Atpase CSERCA) futile cycle has been suggested for brite! beige fat ceus) where Adrenergically stimulated Ca 2+ release from intracellular depots is returned. to these depots through ATo- e through Ato- furnished SERCA actively uggested here to originate The ATP is Guggested here to mainly From glycolysis
