What is the body's defense against ROS? Antioxidants (Vitamin E, Vitamin C, cysteine, glutathione, albumin, ceruloplasmin, transferrin) How does a hypertonic solution alter osmolality? Increases solute concentration, causing INCREASED osmolality. Causes cells to SHRINK. What lab values are elevated as we age? Interleukin 1, tumor necrosis factor-alpha, and C-reactive protein Role of hepatocytes Acetyl CoA is processed by hepatocytes and transforms to 3 ketone bodies: 1. Acetoa...
