Why do lipids need a transport carrier?
Lipids are insoluble in water, so they need transport carriers like lipoproteins to travel in the bloodstream. These lipoproteins encapsulate the lipids, allowing them to be transported to various tissues throughout the body for energy production or storage.
What happens to the glycerol produced from the hydrolysis of triacylglycerols in adipose tissues?
Glycerol is released into the bloodstream from adipose tissues and can be used by various tissues for energy production through a process called glycolysis. It can also be converted into glucose in the liver through gluconeogenesis to maintain blood glucose levels.
In the flowering plants food is transported in what form?
In a flowering plant, the glucose is formed during photosynthesis is stored in the form of starch(insoluble)...but when it is needed, it is converted to sucrose(soluble) which flows through the phloem and is utilized, while rest is again converted to starch and storedhence, it is transported in the form of sucrose
What lipids is used for energy storage-glycolipids glycerophospholipids csphingolipids triacylglycerols spingophospholipids?
Triacylglycerols (TGs) are the primary lipids used for energy storage in the body. They consist of a glycerol molecule attached to three fatty acid chains and are stored in adipose tissue until they are broken down for energy production.
Why is it important that Keratin is insoluble?
Keratin being insoluble helps provide structural strength and rigidity to cells and tissues where it is found, such as in hair, nails, and skin. This insolubility ensures that keratin can maintain its shape and function effectively in these structures.
Why are triacylglycerols packaged into lipoproteins with cholesterol phospholipids and apolipoproteins for transportation in plasma?
Triacylglycerols are packaged into lipoproteins as they are too large and hydrophobic to be transported in plasma.
Does vldl carries triacylglycerols from intestine to the fat cells?
VLDL (very low-density lipoprotein) primarily carries triglycerides synthesized in the liver to various tissues in the body, including fat cells (adipocytes). Triglycerides absorbed from the intestines are typically packaged into chylomicrons and transported to tissues via the lymphatic system.
What is unesterified fatty acid?
Free fatty acids which occur in plasma as a result of lipolysis in adipose tissue or when plasma triacylglycerols are taken into tissues.

Why are vascular tissues called conducting tissues?
Because water, minerals and prepared food materials are conducted (transported) through these tissues.

How is most carbon dioxide transported from tissues to the lungs?
Bicarbonate Ions
Which is the enzyme tha hydrolyzes triacylglycerols?
Lipase is the enzyme that hydrolyzes lipids.
How is oxygen transported by blood from lungs to tissues?
Oxygen is transported by blood from the lungs to tissues primarily by binding to hemoglobin in red blood cells. Hemoglobin carries oxygen from the lungs to tissues where it is released for cellular respiration. Through this process, oxygen diffuses from high concentrations in the lungs to areas with lower concentrations in the body tissues.
What is the main lipid stored in animals?
Triacylglycerols
Two substances that are transported in blood?
Oxygen and carbon dioxide are two substances transported in the blood. Oxygen is carried from the lungs to body tissues by red blood cells, while carbon dioxide is transported from body tissues back to the lungs for elimination.
