Concept explainers
Interpretation:
The lipoproteins which transport exogenous and endogenous lipids should be determined from the given lipoproteins.
Concept introduction:
Lipids are
Lipoproteins are a biochemical assembly that contains both proteins and lipids.
Chylomicrons are lipoprotein particles that consist of triglycerides, phospholipids, cholesterol and proteins. They transport dietary lipids from the intestines to other locations in the body.
The endogenous lipid transport system conveys lipid from liver to peripheral tissues and back to the liver.

- In the hydrolysis of lipids a 'pancreatin' solution is used. This is a mixture of pancreatic enzymes. These would include all of the following EXCEPT for Choose one from the following: (A) lipase (B) amylase (C) dipeptidase (D) trypsinogen (E) chymotrypsinarrow_forwardWhich molecular structure (VLDL, LDL, or HDL) is responsible for transporting cholesterol from peripheral tissues to the liver?arrow_forwardPhosphotidyicholine is a structural lipid in the liver plasma membrane that is essential for the export of fatty acids and tríacylglycerol from liver. A diet low in choline will contribute to fatty liver disease due to inefficiant lipid export from liver. Which lipoprotein would likely be involved in the phophotidlycholine-depedent export of lipid from liver? O LDL O albumin O HDL O VLDLarrow_forward
- How do lipoproteins transport water-insoluble lipid molecules in the bloodstream?arrow_forwardOn the right is a diagram of plasma concentration of three metabolites: glucose, B- hydroxybutyrate, and free fatty acid of an experimental animal over weeks of starvation. 4. (a) Label the lines with the names of the three metabolites. Yellow: Red: 10 20 30 40 Blue: Days of starvation (b) What factor in the plasma binds to and transports free fatty acid (c) Where was B-hydroxybutyrate produced? Why it is produced? What are the purposes of producing it (d) How B-hydroxybutyrate is used as fuel in extrahepatic cells? Write down the reactions, enzymes, and cofactors (No need to elaborate on the TCA cycle). (e) How many ATP molecules or equivalent are generated after complete oxidation of one molecule of B-hydroxybutyrate? Show your calculations. Hint: You need to consider ATP consumption for bypassed steps that may normally yield or consume AT Plasma concentration (mM)arrow_forwardWhat is the reason that amino acid degradation spikes approximately 24 hours after starting a fast? (A) The brain adapts to using ketone bodies, and amino acids serve as the primary precursors for ketone bodies.(B) Red blood cells begin using amino acids to drive their citric acid cycle.(C) Amino acids are broken down and used to replenish glycogen. (D) The liver needs to make glucose for brain and RBCs, and amino acids provide the carbon skeleton for gluconeogenesis.(E) The ammonia released from amino acid breakdown is a substrate for b-oxidation, which increases during prolonged fasting.arrow_forward
- When LDL (low density lipoprotein) is taken up by cells during pinocytosis, all of the following steps in the processing of LDL and its receptor protein occur, with the exception of: LDL is digested in lysosomes, releasing cholesterol to the cytoplasm LDL receptors are digested in the lysosomes along with the LDL LDL attaches to LDL receptors, which form clathrin-coated vesicles the endosomes fuse with lysosomes for digestion of the LDL the vesicles fuse with endosomes, and LDL receptors are recycledarrow_forwardWhich of the following describes the function of lipoprotein lipase? Select one: a. It catalyzes the synthesis of lipoproteins b. It helps recycle unused cholesterol by converting to bile salts c. It helps to transport VLDL's in the blood d. It cleaves fatty acids from chylomicrons e. It helps to increase concentration of "good cholesterol"arrow_forwardHow does a ketogenic diet decrease LDL and increase HDL? (explain in detail on a molecular level)arrow_forward
- Why must cholesterol be transported through the bloodstream in lipoprotein particles?arrow_forwardWhich of the following statements concerning cholesterol regulation is true? (A) SREBP localizes to the ER when cellular cholesterol levels are low.(B) HMG CoA reductase degradation is inhibited when exogenous cholesterol is plentiful.(C) Binding of cholesterol to SREBP causes SREBP to move to the nucleus.(D) Low cellular energy triggers phosphorylation and inhibition of HMG CoA reductase.(E) SREBP binds to a sterol regulatory element in the HMG-CoA reductase gene promoter to decrease gene expression.arrow_forwardLipoproteins are relatively large, combined clumps of both protein and lipid molecules that circulate in the blood of mammals. They come in two forms, called HDL and LDL, and they act like suitcases to move cholesterol, fatty acid remnants, triglycerides, and phospholipids from one place to another through the bloodstream. (LDL recirculates lipids throughout the body, while HDL takes lipids to the liver to excrete them in feces.) Given that lipids are hydrophobic and proteins can be hydrophilic, which of the following statements is correct? (a) The lipid portion of LDL does not dissolve in the bloodstream, while the lipid portion of HDL does. (b) The protein portions of both LDL and HDL can dissolve or interact with the water molecules in the bloodstream. (c) Neither the protein nor the lipid portions of LDL molecules can interact with water molecules in the bloodstream. (d) Both the protein and the lipid portions of HDL molecules can interact with water molecules in the bloodstream.…arrow_forward
