The endoplasmic reticulum (ER) is a large organelle made of membranous sheets and tubules that begin near the nucleus and extend across the cell. The endoplasmic reticulum creates, packages, and secretes many of the products created by a cell.
Oct 18, 2024 · endoplasmic reticulum (ER), in biology, a continuous membrane system that forms a series of flattened sacs within the cytoplasm of eukaryotic cells and serves multiple functions, being important particularly in the synthesis, folding, modification, and transport of proteins . All eukaryotic cells contain an endoplasmic reticulum (ER).

Jul 1, 2024 · This article offers an insightful exploration of Erbium, detailing its definition, intrinsic properties, and the multitude of its applications ranging from telecommunications to medical equipment. Through illustrative examples, you’ll discover why Erbium is not just another element but a cornerstone in advancing modern innovations.
The endoplasmic reticulum (ER) is a series of interconnected membranous tubules that collectively modify proteins and synthesize lipids. However, these two functions are performed in separate areas of the endoplasmic reticulum: the rough endoplasmic reticulum and the smooth endoplasmic reticulum, respectively.
Mar 7, 2021 · In chemistry and physics, activation energy is the minimum amount of energy needed to start a chemical reaction. Reactants often get activation energy from heat, but sometimes energy comes from light or energy released by other chemical reactions.
Nov 21, 2023 · A micelle is a spherical structure that forms in water by the aggregation of surfactant molecules, with their hydrophobic (water-hating) tails inward and hydrophilic (water-loving) heads outward. Micelles are like tiny, invisible soap bubbles in solutions. When soap or similar substances dissolve in water, they group together into tiny ...
