The roles of dinoflagellates in coral bleaching and the generation of red tides. Introduction: Dinoflagellates are marine photosynthetic eukaryotes. Their chloroplasts appear golden brown due to the presence of a mixture of accessory and photosynthetic pigments. Some species are endosymbionts that live within the cells of corals, an invertebrate animal and impart them golden or greenish color. Endosymbiotic dinoflagellates supply the corals with nutrients produced from photosynthesis and, in turn, the corals provide them with photosynthetic substrates. This endosymbiotic relationship is responsible for the color of the corals. These protozoans, dinoflagellates also produce red tides in the ocean.

The roles of dinoflagellates in coral bleaching and the generation of red tides.

Introduction:

Dinoflagellates are marine photosynthetic eukaryotes. Their chloroplasts appear golden brown due to the presence of a mixture of accessory and photosynthetic pigments. Some species are endosymbionts that live within the cells of corals, an invertebrate animal and impart them golden or greenish color.

Endosymbiotic dinoflagellates supply the corals with nutrients produced from photosynthesis and, in turn, the corals provide them with photosynthetic substrates. This endosymbiotic relationship is responsible for the color of the corals. These protozoans, dinoflagellates also produce red tides in the ocean.

Glitazones reduce insulin resistance by binding to a transcription factor in adipocytes, thereby reducing thesecretion of fatty acids. Glitazones are taken orally (in pill form). Using pharmacokinetic modeling, deriveequations to describe how the concentration of glitazones varies in the plasma as a function of time. Yourequations should be of the form: dCglitazone /dt = something, or dMglitazone /dt = something. Your model shouldinclude three compartments: the gut, the plasma, and the fatty tissues. Make sure to include a diagram thatillustrates your thinking, state all assumptions, and define your variables. Do not solve the equations.

Case Study—Ella Review the case study and then answer Parts A through F. Ella has a family history of diabetes. She wants to follow a healthful eating pattern that can lower her risk for developing this condition. Her dietitian recommends a goal of 450 to 600 kcal per meal and advises Ella to follow the Acceptable Macronutrient Distribution Range (AMDR) for carbohydrates and the Dietary Guidelines for Americans 2015-2020, which recommend limiting added sugar. She also recommends that Ella choose whole grains rather than processed grains. Ella decides to pack a lunch to take to work every day. This morning she’s making a sandwich for her lunch.
