Chapter : Lipid metabolism
Triasilgliserol (TAG) is stored in adipose tissue in the form of lipoproteins that will circulate in the blood plasma. By the time TAG reaches the adipose network, it will be hydrolyzed. Explain:
a. TAG hydrolysis reaction
b. regulation of storage and use of lipids in the animal's body
Q20:
Hypothetical scenerio:
When the membrane potential is 80mV across the digestive vacuoles (DV), inside positive, the Vmax for VF-6-2 efflux is 15pmol/h. However, when the membrane potential is 80mV inside negative, the Vmax of VF-6-2 efflux drops to near zero. Researchers suggest an H+ P-type ATPase is also in the membrane and is required for VF-6-2 efflux.
Do these data support their suggestion? What type of transporter might PfCRT be? How can vanadate be used to potentially test their idea?

- 3) Read the situations below and indicate which of the four methods of enzyme regulation is occurring for each. a) The energy-carrying molecule ATP is made by the enzyme ATP synthase. Muscle cells use a lot of energy and also have higher amounts of the ATP synthase enzyme than many other cell types. General mechanism of enzyme regulation: S b) Prostaglandins are messenger molecules involved in the inflammatory response, as well as the perception of pain. They are synthesized from polyunsaturated fatty acid substrates by an enzym called cyclo-oxygenase. "Ibuprofen" is the active ingredient in a variety of anti-inflammatory medications such as Motrin® and Advil®. It reduces pain and swelling by binding to a hydrophobic channel in the active site of cyclo-oxygenase, blocking the polyunsaturated fatty acids from binding to the enzyme, and therefore stopping production of prostaglandins.
