be differences in the "sides" of a cell when we talk about cellular polarity. (3pts) The membranes of cells also show "polarity". Name at least 3 separate characteristics of the membrane in the image below that illustrate polarity 1. Chol 0 Gang SPM OPI TM1 TM2 Acyl cytoplasm 2. (3pts) The blue shaded regions of the membrane are lipid rafts, which show differences in lipid and protein composition from other parts of the membrane. These differences restrict movement of molecules ...

Abstract: Accumulating evidence indicates that obesity is closely associated with an increased risk of metabolic diseases such as insulin resistance, type 2 diabetes, dyslipidemia and nonalcoholic fatty liver disease. Obesity results from an imbalance between food intake and energy expenditure, which leads to an excessive accumulation of adipose tissue. Adipose tissue is now recognized not only as a main site of storage of excess energy derived from food intake but also as an endocrine orga...
