Which process causes increased oxygen consumption by skeletal muscle during shivering thermogenesis in mammals?

💡 Explanation

When shivering, ATP hydrolysis occurs extensively because muscles rapidly contract and relax without performing external work, leading to dissipation of energy as heat for thermoregulation. Therefore ATP hydrolysis results in increased oxygen consumption, rather than alternatives involving blood cell production, glycogen synthesis, or fat oxidation for cellular repair functions.
