The beta oxidation pathway degrades activated fatty acids (acyl-coa) to acetyl-coa, which then enters the citric acid cycle. additional enzymes are required to oxidize unsaturated, odd-chain, long-chain, and branched fatty acids. which of the following statements are true? a. a 14-carbon monounsaturated fatty acid with cis configuration yields more atp than a 14-carbon saturated fatty acid. b. enoyl-coa isomerase, an enzyme that converts cis double bonds to trans double bonds in fatty acid metabolism, bypasses a step that reduces q, resulting in a higher atp yield. c. even-chain saturated fatty acids are oxidized to acetyl-coa in the beta oxidation pathway. d. complete catabolism of the three-carbon remnant of a 15-carbon fatty acid requires some citric acid cycle enzymes. e. trans double bonds in unsaturated fatty acids are not recognized by beta oxidation enzymes. f. the final round of beta oxidation for a 13-carbon saturated fatty acid yields acetyl-coa and propionyl-coa, a three-carbon fragment.

The last few miles of the marathon are the most difficult for heather, her hair plastered to her head, sweat clinging to her arms, and her legs already feeling as if they had nothing left, just dead weight. after grabbing a cup of ice water, she feels the ice cubes smash against her nose as she gulps some cool refreshment and keeps on running. in these last few miles, the breeze kicks up and she finally feels some coolness against her skin. drips of sweat, once clinging to her forehead, now spill down, and heather feels more pain as the sweat flows into her eyes. which of the following is the most likely reason why the ice struck heather’s nose when she took a drink? a) water can function as a solvent. b) water can store large amounts of heat. c) water can moderate temperatures through evaporative cooling. d) the density of water decreases when it freezes. e) water has a cohesive nature. sweat remained on heather’s forehead and arms because of the a) high salt content of sweat b) cohesive nature of water c) ability of water to moderate heat d) high evaporative cooling effect of water e) ability of water to act as a solvent

What is a main difference between a mixture and a pure substance? a mixture is only a liquid, but a pure substance can be in any state. a mixture looks the same throughout, but a pure substance does not.1 a mixture can vary in composition, but a pure substance has a set composlo a mixture can be made up of a single compound, but a pure substance car
