    semi-permeable membrane. This process is called diffusion. In diffusion, particles move in motion at a random speed from a high concentration to an area of low concentration until all of the molecules are dispersed evenly. It is important to remember that involvement with diffusion depends on the concentration. The greater the concentration, the greater the rate of diffusion. Also known as the concentration gradient. Another process in which particles enter and leave cells is osmosis which is a…

    How the human body works Cell membrane: A cell membrane is a thin layer that forms a semi- permeable barrier around the outer surface of the cytoplasm of the cell and controls the movement of substances into and out of the cell. Nucleus: It contains DNA for making new cells and organisms and also controls the reaction in the cell. Chromosomes: Thread- like structures found in the nucleus of the cell which carry the genetic information Cytoplasm: The liquid gel which makes up a lot of the body of…

    basale, which is constantly regenerating (figure 1). During movement, these layers undergo extreme deformation, having a great impact to the underlying network of extra cellular matrix components. The stratum basale is maintained by tight junctions such as Claudins, ZO-1, Occludins, forming a barrier between cells. The dermoepidermal junction is formed by the presence of lipids on the basement membrane, which provides an additional barrier. Cells within the epidermis include keratinocytes,…

    Analyzing Various Permeable Bags Placed in Different Concentrations of Water and Sucrose Introduction Osmosis is defined as the movement of water from a region of water that has a higher potential to a region of water that has a lower potential through semipermeable membranes. There are three types of solutions, hypertonic, hypotonic, and isotonic. Hypertonic solutions have a higher concentration of solute while hypotonic solutions have a lower concentration of solute. Isotonic solutions have…

    freezing point of the bacteria cells, enhancing supercooling. With bacteria, adding glycerol to final concentration of 15% will help protect from damage of freezing and thawing. When the freezing point of bacterial cells lowered by the use of glycerol, its prevent the formation of ice crystal which can cause intracellular injuries. Generally, the colder the storage temperature, the longer the culture will retain viable cells. The increase in salt concentration, can damage the bacterial cell by…

    Docking: In molecular modeling field, docking is a method which assumes the desired orientation of one molecule to a second molecule when bound to each other, to form a stable complex. Knowledge of the orientations can be used to assume the strength of association or binding affinity between the two molecules. The associations between biologically relevant molecules such as proteins, nucleic acids, carbohydrates, and lipids play a key role in signal transduction. Thus, the relative alignment of…

    Anything higher than 1.0M resulted in a hypotonic concentration. A cell membrane is a thin layer surrounding a cell and it in control of what enters and leaves a cell. The membranes purpose is to control the internal environment of a cell. Water molecules, because of their small size, move across cell membranes. Osmosis occurs when there are more water molecules traveling in one direction than the other. The solvent from the side of weaker concentration (hypertonic) usually moves to the side of…

    The distilled water was needless to say a hypertonic solution because more molecules lay outside of the potato, while the saltwater was naturally hypotonic because of the higher concentration in it. The Tap Water solution, however was the oddball of the three, Tap water is dependent on the location and quality of your water meaning it could've been hypotonic or hypertonic. In this experiment the potato was used to model a cell experiencing osmosis, like a cell, the potato will let really small…

    substances across the cell membrane. The cell membrane is found on the outside of the cell and controls what goes in and out of the cell. It is selectively permeable. The membrane has cells that share common structural features, including an outer boundary. All cells are contained by a cell membrane, which keeps the pieces inside. It consists of a phospholipid bilayer with proteins embedded throughout. It separates what’s inside the cell, some of the proteins. The plasma membrane helps maintain…
