Which of the following fatty acids, if incorporated into a typical eukaryotic membrane phospholipid, would be the most likely to increase that membrane's fluidity? arachidonic acid with 20 carbons and two carbon-to-carbon double bonds stearic acid, with 18 carbons and no carbon-to-carbon double bonds None of the above arachidonic acid with 20 carbons and three carbon-to-carbon double bonds
Which of the following statements best describes the absorption of glucose? Absorption of glucose requires digestion by aminopeptidases on absorptive epithelial microvilli before absorption of the carbohydrate smaller units such as glucose. Absorption of glucose requires an electrochemical gradient of high extracellular K+ set up by primary active transport. Absorption of glucose occurs at villi and crypts mainly in the duodenum where amylases break down carbohydrates into glucose. Absorption of glucose occurs at the transporting epithelia in the small intestine and is a secondary active transport that requires a Na+gradient
What effect will increasing the proportion of unsaturated fatty acids in the bilayer have on the membrane's permeability to glucose? A) Permeability to glucose will increase. B) Permeability to glucose will decrese. C) Permeability to glucose will stay the same. D) Permeability will decrease initially then increase as the bilyaer fills with glucose.

Diabetic ketoacidosis is characterized by an increased level of ketone bodies, which causes metabolic acidosis. A patient in diabetic ketoacidosis will have an altered rate of ventilation. Will the patient be hyperventilating or hypoventilating? How will a change in the rate and depth of ventilation compensate for an acidosis that is metabolic in nature?
Which of the following statements describing the mobilization and utilization of fatty acids in the body is INCORRECT? Answers A-E A. Fatty acids are excellent fuels for skeletal muscle. B. On a molar basis, fatty acid oxidation to carbon dioxide and water yields more ATP than do carbohydrates C. It is Coenzyme A derivatives of fatty acids that are beta-oxidized D. Fatty acids are transported in plasma bound to albumin E. Fatty acid oxidation to carbon dioxide and water does not require a functional Krebs cycle
Consider the following nutrients: (water, simple sugar (glucose), amino acid, and fatty acid). Describe where each one is absorbed in the small intestine and which mechanism (active transport, facilitated diffusion, or simple diffusion) drives their movement into the bloodstream. Please be detailed with your explanation
The micrographs of areolar and adipose tissue both show cells (fibroblasts and adipocytes), but the density of cells in the two tissues is very different. What do you think causes this difference?
Purpose: of this assignment is to explain how energy is extracted from foods and used to produce ATP and also describe how the body synthesizes new molecules. Describe how the body synthesizes new molecules from glucose, fatty acids, and amino acids?
