Oxygen is toxic to anaerobic organisms primarily due to the fact that they lack the ability to express the enzymes needed to metabolize the toxic intermediates generated from oxygen utilization. true or false

The number of calories used during physical exercise is greater than the number of calories used for the movements themselves. This may be caused in part by exercise-induced expression of uncoupling protein 1 (UCP1) in subcutaneous fat. Subcutaneous fat is mostly white fat cells but can also contain brown fat cells in mice and humans. As part of a thermogenesis program, UCP1 directly reduces the proton gradient driving oxidative phosphorylation. UCP1 expression is a characteristic of brown fat cells only and is induced by the protein irisin. The data in Table 1 address the relationship between exercise and: in both wild-type mice and mice with overexpression skeletal muscle PGC-1a (a transcription factor whose expression in skeletal muscle is induced by exercise). Table 1 Effects of Exercise and PGC-1a on UCP1, FNDC5, Irisin, and Adiponectin • expression of UCP1 in subcutaneous fat cells, • expression of FNDC5 (a transmembrane protein in skeletal muscle plasma membranes), • blood…
