The relatively long half-life of lipid-soluble hormones (steroid hormones) compared to water- soluble hormones is due in part to
the way that these hormones are passed into the filtrate from the glomerular capillaries. From the list below select the best explanation for why lipid-soluble (steroid) hormones have a relatively long half-life. A) Steroid hormones travel in the plasma on large transport proteins that cannot pass through the filtration membrane. B) The large size of the steroid hormones prevents them from passing through the filtration membrane. C) Steroid hormones are absorbed by target cells before they can reach the kidneys D) The relatively small size of steroid hormones allows them to easily pass back into the peritubular capillaries if released into the filtrate
The electron transport chain (ETC) is the final step of cellular respiration and takes place in the mitochondrion.
The final step in cellular respiration is the electron transport chain. This is sometimes abbreviated as ETC. ETC needs oxygen, which means aerobic process. It occurs at the edges of the inner lining of mitochondria. These handles are called cristae.
