cells biology

• The nucleus contains the cell's DNA and controls cell functions.
• Cholesterol helps maintain fluidity and stability of the cell membrane by interacting with phospholipid tails.
• Cholesterol helps maintain fluidity and stability of the cell membrane by reducing the tendency to phase separation.
• Phospholipids are amphiphilic molecules with hydrophobic tails and polar heads that form the bilayer structure of the cell membrane.
• The cell membrane is composed of phospholipids, cholesterol, proteins, and carbohydrates.
• The cell membrane is composed of phospholipids, cholesterol, proteins, and carbohydrates.
• Lysosomes contain digestive enzymes that break down waste materials, foreign particles, and cell components.
• Mitochondria produce most of the cell's supply of adenosine triphosphate (ATP), which is the chemical energy currency of cells.
• Phospholipids have hydrophilic heads that face outward and hydrophobic tails that face inward.
• Cell membranes are composed of phospholipids, cholesterol, proteins, and carbohydrates.
• Cholesterol is embedded between the phospholipid layers to maintain fluidity.
• Phosphatidylinositol is involved in signal transduction pathways that regulate various cellular processes.
• Glycolipids are lipids attached to carbohydrates, which can be used as markers on the surface of cells.
• Glycolipids, also known as glycosphingolipids, contain carbohydrates attached to sphingosine instead of fatty acids.
• Proteins embedded in the plasma membrane can act as receptors or channels.
• Glycolipids are lipids that contain carbohydrates, such as gangliosides found on neurons.
• Sphingomyelin is an important component of myelin sheaths surrounding nerve fibers.
• Ribosomes synthesize proteins using information from mRNA.
• Phosphatidylinositol (PI) is an important signaling molecule involved in various processes including muscle contraction, neurotransmitter release, and gene expression.
• Carbohydrate chains on glycoproteins and glycolipids serve as recognition sites for other cells.
• Sphingomyelin is a type of glycerophospholipid that has a sphingoid base instead of glycerol.
• Mitochondria generate ATP through aerobic respiration.
• Glycocalyx - A layer of polysaccharides attached to the surface of the cell membrane.
• Receptor proteins bind specific signaling molecules called ligands.
• Receptor proteins bind specific signaling molecules called ligands.
• Chloroplasts are organelles found only in plant cells where photosynthesis occurs.
• Chloroplasts are organelles found only in plant cells and some protists.
• Vacuoles store water, nutrients, pigments, and wastes within plant cells.
• Sphingomyelin is an example of a glycolipid found in nerve tissue.
• Ribosomes are small structures made up of RNA and protein molecules responsible for synthesizing proteins.
• Glycocalyx - A layer of polysaccharides attached to the outer surface of the cell membrane.
