What else can I help you with?
What macromolecule is sex hormones?
Steroids are a class of lipid molecules that have 4 carbon rings.
What are tryglisorides?
Triglycerides are molecules made from three molecules, usually fatty acids attached to a glycerol molecule. They are more often known as lipids, or fats. A fatty acid is a carboxylic acid with a long alkyl group.
Why do the passenger molecules need to be helped by the carrier molecules?
Carrier proteins aid in facilitated diffusion by binding a particular substance, then altering their shape to bring that substance into or out of the cell. Those molecules can not go through the lipid layer on their own as they can not dissolve in lipids. (This is sometimes called lipophobia). This relationship is somewhat like an enzyme and substrate combination.
The ER sends proteins and lipids it makes to what to be modified?
The endoplasmic reticulum (ER) sends proteins and lipids in membranous vesicles to the Golgi body (also known as the Golgi apparatus or the Golgi complex). The Golgi body looks like a stack of pita breads; it resembles the ER. There, the membranous vesicles containing proteins or lipids will fuse with one side of the Golgi body known as the cis face.Inside the Golgi body, proteins and lipids will have carbohydrate molecules added to them, forming glycoproteins (proteins with carbohydrates attached) and glycolipids (lipids with carbohydrates attached). After being modified, the glycoproteins and glycolipids will exit the Golgi body in membranous vesicles through the trans face (the side opposite the cisface).
What keeps a cell membrane constantly moving around a cell?
A cell membrane is mostly a film of lipid molecules enclosing a volume of liquid. The lipid film is in a fluid-like phase, and thus the molecules are always in motion. All molecules are subject to the laws of thermodynamics, including the lipids in a cellular membrane. Unless matter is frozen to -273 degrees Celsius, there will always be some movement.
What is the process of breaking lipids into smaller droplets?
The process of breaking lipids into smaller droplets is called emulsification. This typically involves the use of an emulsifier, which can help stabilize the mixture of lipids and water. Emulsification increases the surface area of lipids, making them easier to digest and absorb.
How are lipids broken down in the body?
Lipids are broken down in the body through a process called digestion. This process starts in the small intestine where enzymes break down the lipids into smaller molecules like fatty acids and glycerol. These smaller molecules are then absorbed into the bloodstream and used for energy or stored in fat cells for later use.
When you ingest large molecules such as lipids carbohydrates and proteins they must undergo catabolic reactions whereby enzymes split these molecules?
Yes, large molecules like lipids, carbohydrates, and proteins are broken down through catabolic reactions in the body. Enzymes help in the process of breaking these complex molecules into smaller, more manageable components that can be absorbed and utilized by the body for energy and other functions. This catabolic process releases energy stored in these molecules for various cellular activities.
Do all organisms use the same process to produce lipids?
No not all organisms use the same process to produce lipids. Lipids are produced in a variety of ways depending on the organism. Generally lipids are produced through either biosynthesis or digestion. Biosynthesis is a metabolic process that involves the building of molecules from smaller components often with the input of energy from ATP. This is the process used by plants and some microorganisms to produce lipids. Digestion is the process of breaking down complex molecules into simpler components. This is the process used by animals to obtain lipids from food sources.In some cases lipids are also produced through chemical processes such as the hydrogenation of vegetable oils.
Carbohydrates are chains of what smaller organic molecule?
Carbohydrates are chains of smaller organic molecules called monosaccharides.
Organelle in animal cells where enzymes break down large molecules into smaller molecules?
Smooth Endoplasmic reticulum (SER) synthesize lipids whereas Peroxisomes (one of two types of microbodies) break down lipids into useable molecules as well as catalyze detox rxns in the liver. Rough ER droduce protein products whereas proteins are broken down in the stomach by protease enzymes in the stomach. There may be an organelle responsible for that but I don't remember.
Which organelle is responsible for breaking down and digesting things?
The organelle responsible for breaking down and digesting things is the lysosome. Lysosomes contain enzymes that can break down various molecules, such as proteins, nucleic acids, carbohydrates, and lipids, into smaller components that can be used by the cell.
What happens when lipids die?
When lipids "die," they break down into fatty acids, glycerol, and other smaller molecules through a process called lipolysis. These smaller components can then be further metabolized by cells for energy production or stored for future use. The breakdown of lipids is a normal part of the body's metabolic processes.
Do lipids need to be digested before they can be absorbed?
Yes, lipids need to be broken down into smaller molecules like fatty acids and glycerol through the process of digestion before they can be absorbed in the small intestine. This process is facilitated by enzymes such as lipase.
Are lipids considered a macromolecule?
Yes, lipids are considered a macromolecule because they are large molecules made up of smaller building blocks called fatty acids.
What is a protein chain of linked smaller molecules called?
amino acids or lipids? Amino acids
How do chloroform dissolve lipids?
Chloroform dissolves lipids by disrupting the hydrogen bonding and hydrophobic interactions that hold lipid molecules together. This allows chloroform to insert itself between lipid molecules, breaking up their structure and forming a solution.
