Effect Of Different Temperature & Different Concentration Through Diffusion Of The Membrane

Introduction Biology may be a scientific study of life within which we examine the essential components to living things and their key habits to survival. to grasp this process, we first have a look at the organism’s cell. The cell was discovered and derived because the basic unit of life by British scientist, scientist. From his study, he concocted the thought that everything an organism has to survive is found, processed, and utilized within the cell. He then realized that...

Understand Plant Membrane Trafficking Using Cellulose Synthase Complex As A Cargo

In the late 1800s, the endomembrane system was first discovered by scientist Camillo Golgi, which was the start point of this special type of transport in cell. Endomembrane traffic in eukaryotic cells have many functions within cell growth and plant development, partially as a means of communication and balancing membrane system. (Serge Feyder et al. 2015) Thanks to Randy Schekman and Peter Novick’s work, the secretory pathway in yeast was the first identified trafficking pathway, taking advantage of eukaryotic intracellular...

The Effect Of Different Concentrations Of Ethanol On The Plasma Membrane Of Beetroot Cells

Introduction The membranes of cells are made up of a fluid imitating, semi-permeable plasma membrane. This is made up of a phospholipid bilayer. A phospholipid bilayer is comprised of phospholipids (see figure 1) and various membrane proteins. The lipid tails of the phospholipids are hydrophobic (repel water) and the phosphate heads are hydrophilic (attract water). In order to ensure the hydrophobic tails remain dry, these phospholipids form bilayers. An emergent property of this is the solution on the inside of...

The Effects Of pH On The Plasma Membrane And Betacyanin Absorbance In Beet Roots

Abstract When looking at Beetroots the effects of pH can be seen through the pigment of Betacyanin stored within the cell membrane by testing absorbance of the pigment released in a solution due to effects pH has on the permeability of the membrane. The solutions applied to the cells roots leads the cells to become disrupted causing an open membrane which allows the leakage of betacyanin because it diffuses itself into the cell membrane creating distortion and leakage of pigment...

Improvement Of Polyamide Reverse Osmosis Membranes By Coating With Ag/chitosan Nanodispersion Prepared By Gamma Radiation

Abstract Silver/Chitosan nanodispersion (Ag/CS) prepared by gamma ray was used to modify the thin-film composite reverse osmosis (RO) membrane. The silver nitrate solutions were added to the chitosan solution with different concentrations of 5 to 20 (wt/wt %) and exposed to gamma radiation at different irradiation doses. The size of the silver/chitosan nanodispersion is investigated by transmission electron microscopy (TEM). The membranes characterized by FT-IR spectroscopy, scanning electron microscope (SEM) and contact angle measurement. Contact angle measurements showed that the...
