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

- Q1: Why is it important that enzymes are not permanently altered when they bind with substrate molecules?

Q3: If a cell was unable to produce a particular enzyme necessary for a metabolic pathway, describe how the absence of that enzyme would affect the cell.arrow_forwardHypothesis: Mammalian alpha amylase (optimal temperature 37*C) has a higher activity at pH 6.9 (intestinal pH) compared to its activity at pH 3.5 (gastric pH).

When mice are given a derivative of cerulenin (a fungal epoxide) named C75, their appetite is suppressed and they rapidly lose weight. Cerulenin and its derivatives have been shown to be potent inhibitors of fatty acid synthase (FAS). Suggest how C75 might act as a potential weight reduction drug"Thanks.

- Q4: Explain in detail ,Why isn't the pentose phosphate pathway very active in muscle tissues compared to adipose tissue?arrow_forwardB) 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 ouier cem types. General mechanism of enzyme regulation: /1 b) Prostaglandins are messenger molecules involved in the inflammatory response, as well as th perception of pain. They are synthesized from polyunsaturated fatty acid substrates by an enzyn 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.

AMP + P₁ O Macmillan Learning Hydrolysis is a reaction in which a large molecule is split into two smaller molecules upon the addition of water, H₂O. Adenosine triphosphate, ATP, has one more inorganic phosphate group than does adenosine diphosphate, ADP. ADP has two phosphate groups, whereas adenosine monophosphate, AMP, has one.
