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...

All Domains Jean Inman Questions with Explanations of Answers Which amino acids must be present in a parenteral solution? a. valine, leucine, glycine, alanine b. tryptophan, phenylalanine, threonine, isoleucine c. phenylalanine, methionine, arginine, tyrosine d. lysine, glutamic acid, alanine, glycine - ANS- b. tryptophan, phenylalanine, threonine, isoleucine A parenteral solution requires adequate supplementation of all essential amino acids. Essential amino acids = those that can...

Humans produce sweat as a cooling mechanism to maintain a stable internal temperature. Which of the following best explains how the properties of water contribute to this physiological process? - ANSWER The high heat of vaporization of water allows the body to remove excess heat through a phase change of water from liquid to gas A student placed a semipermeable membrane inside a U-shaped channel with two chambers, as shown. The membrane permits the movement of water but not salt. The...

Question 1 (1 point) Question 1 Saved (08_05_01) If A molecule of triglyceride is burned in one cell at the same time that a molecule of glucose is burned in another cell, what will be true of this scenario? Question 1 options: 1) The cell burning glucose will make more ATP than the cell burning fat 2) The cell burning glucose can still get ATP if oxygen is absent3) The cell burning fat can still get ATP if oxygen is absent 4) b and c are correct 2) The cell burning glucose can still...

b-oxidation needs mitochondria, sends FA (aceyl-CoA) to mitochondria via carnitine - b-oxidation occurs and acetyl-CoA occurs - acetyl-CoA cannot convert to pyruvate so cannot engage in gluconeogenesis Correct Answer-so why cant acetyl-coa derived from beta oxidation be used to convert into glucose? beta-oxidation, then can enter TCA (acetyl-coa_ Correct Answer-how do FAs enter TCA cycle? glycolysis Correct Answer-how does glucose enter TCA? conversion to acetyl-CoA or converted into...
