The basal metabolic rate encompasses _____________.

powering ion channels, the heart, and the lungs (among other things)

Gluconeogenesis occurs in which two organs?

The liver (primarily) and the kidneys

16

Those with glucose 6-phosphate dehydrogenase deficiency have a defect in which pathway?

Pentose phosphate pathway
