Figure 9.3 -In Vertebrate Animals, Brown Fat Tissue's Color Is Due to Is

Figure 9.3
-In vertebrate animals, brown fat tissue's color is due to abundant mitochondria. White fat tissue, on the other hand, is specialized for fat storage and contains relatively few mitochondria. Brown fat cells have a specialized protein that dissipates the proton-motive force across the mitochondrial membranes. Which of the following might be the function of the brown fat tissue?

A) to increase the rate of oxidative phosphorylation from its few mitochondria
B) to allow the animals to regulate their metabolic rate when it is especially hot
C) to increase the production of ATP synthase
D) to allow other membranes of the cell to perform mitochondrial function
E) to regulate temperature by converting energy from NADH oxidation to heat
