Question 6 5. Glucose is frequently administrated intravenously to patients as a food source. A new resident at ahospital where you are working suggests administrating glucose-6-phosphate instead. You considerthe possibility that this procedure might save the patient energy. Should you use the resident'ssuggestion? Why or why not?6. Most hormones, such as peptide hormones, exert their effects by binding to cell- surface receptors.However, steroid hormones do so by binding to cytosolic receptors. How is this possible?

Hormones are involved in the signaling molecules which are produced by glands of the multicellular organisms. They are transported to distant organs by the circulatory system. Steroid hormone is any group of hormones that belong to the class of chemical compounds known as steroids and are secreted by the steroid glands.Some hormones, like the peptide hormones, show their effect by binding to the cell surface receptors. But steroid hormones, on the other hand, exert their effects by binding to the cytosolic receptors. Steroid hormones are fat-soluble and hydrophobic in nature. As they are derived from cholesterol, they have hydrophilic functional groups at both ends and carbon backbones that are hydrophobic in nature. Due to this hydrophobic nature, they can diffuse through the cell membrane to reach their receptors. It is energetically favorable for the hydrophobic part of the steroid hormones to enter the lipid bilayers of the cell membrane.
