The Cushing and adrenogenital syndrome. Introduction: The adrenal gland is composed of two glands with different origin of cells and functions. It is located on the superior part of each kidney. The size of the adrenal gland in adult is about 5 cm long and 3 cm wide. In newborns, it weighs nearly 8-10 g; however, half of its weight is reduced at the age 2 years. Involution causes the shrinkage of this gland, and the gland remains about 4 -5 g in adults. The adrenal medulla and adrenal cortex are the inner and outer portions of the adrenal gland, respectively. The adrenal cortex (outer portion) covers the adrenal medulla on all corners, constituting 80%-90% of the adrenal gland. It appears as yellowish in color because of the presence of high cholesterol and other lipids. It secretes more than twenty-five steroid hormones derived from cholesterol. The cortex consists of three layers of tissues with different history and hormone production, namely the zona glomerulosa, the zona fasciculate, and the zona reticularis.

9. Aerobic respiration of one lipid molecule. The lipid is composed of one glycerol molecule connected to two fatty acid tails. One fatty acid is 12 carbons long and the other fatty acid is 18 carbons long in the figure below. Use the information below to determine how much ATP will be produced from the glycerol part of the lipid. Then, in part B, determine how much ATP is produced from the 2 fatty acids of the lipid. Finally put the NADH and ATP yields together from the glycerol and fatty acids (part A and B) to determine your total number of ATP produced per lipid. Assume no other carbon source is available. 18 carbons fatty acids 12 carbons 9 glycerol A. Glycerol is broken down to glyceraldehyde 3-phosphate, a glycolysis intermediate via the following pathway shown in the figure below. Notice this process costs one ATP but generates one FADH2. Continue generating ATP with glyceraldehyde-3-phosphate using the standard pathway and aerobic respiration. glycerol glycerol-3- phosphate…

Normal dive (for diving humans) normal breathing dive normal breathing Oz level CO2 level urgent need to breathe Oz blackout zone high CO2 triggers breathing 6. This diagram shows rates of oxygen depletion and carbon dioxide accumulation in the blood in relation to the levels needed to maintain consciousness and trigger the urgent need to breathe in diving humans. How might the location and slope of the O₂ line differ for diving marine mammals such as whales and dolphins? • How might the location and slope of the CO₂ line differ for diving marine mammals such as whales and dolphins? • • Draw in predicted lines for O2 and CO2, based on your reasoning above. How might the location of the Urgent Need to Breathe line and the O2 Blackout Zone line differ for diving marine mammals? What physiological mechanisms account for each of these differences, resulting in the ability of marine mammals to stay submerged for long periods of time?
