The cell membrane, also known as the plasma membrane, is a double layer of lipids and proteins that surrounds a cell and separates the cytoplasm (the contents of the cell) from its surrounding environment. It is selectively permeable, which means that it only lets certain molecules enter and ...
Describe the fluid-mosaic model of membrane structure. 描述细胞膜的流体镶嵌模型。 answer: The plasma membrane is a phospholipids bilayer with attached or embedded proteins. The phosopholipid molecule has a polar head and nonpolar tails.相关知识点: ...
Describe the composition of plasma and the function of the different components. Human blood: The blood is a fluid that circulates in the body and carry nutrients, water, essential chemicals, and dissolved gases needed by the cells. Its four major components are white blood cell...

It is formed inside primary cell walls and near to plasma membrane. It is thick and consist of cellulose, hemicellulose and lignin. 答: 植物细胞壁由胞间层、初生壁、次生壁三层构成。胞间层位于相邻两个细胞之间,主要化学组成为果胶质,具有可塑性和延展性,随着植物细胞增大,胞间层也被拉大。初生壁...
List at least three functions of the plasma membrane. Describe the mechanical processes of ventilation both inspiration and expiratory. In addition, describe, in details, the three factors influencing airway resistance during ventilation. Briefly explain pulmonary ventilation. ...
It is located in the inner membrane of mitochondria and chloroplast membrane or the plasma membrane of prokaryotic cells. ATP synthesis in oxidative and photosynthetic phosphorylation is catalyzed by the F~ beta subunit using the energy of proton flux across the membranes. Recently, Ohta and Kagawa...
Describe the role of hyaline and fibrocartilage in synchondroses. Describe how lipids and proteins are distributed in the plasma membrane and explain the functions of each. Explain the role of ADH in maintaining water balance, between dehydration and overhydration. ...
contamination and was not included in the analysis. mngs methods pcr-free library preparation and mngs testing whole blood was centrifuged at 1600 g for 10min, and the supernatant was centrifuged at 16,000 g for 10min to obtain plasma. one milliliter of plasma was pipetted into the ...
Protein lateral diffusion is considered anomalous in the plasma membrane. And this diffusion is related to membrane microstructure. In order to better describe the property of protein lateral diffusion and find out the inner relationship between protein lateral diffusion and membrane microstructure, this ...
