Beetroot tissues will be the model investigated in this lab. Specifically the effects of temperature stress on the beetroots cellular membrane. Beetroot is known as Beta Vulgaris, it is one of the healthiest vegetables one can eat with plenty of minerals and vitamins. One of the main vitamins in beetroot is betaine which serve as organic osmolytes that are synthesized or taken from the surroundings by the cells to protect against osmotic stress, high temperature or, drought. Roots of beet also…

All things alive are made of cells. We humans have way too many to count. All the cells cluster and act together in the way so that we can function normally. Thanks to Agre and MacKinnon we now have more knowledge over molecular machines such ass channels, gates, and valves. The fact that water could go through the cell wall has always been a known thing, however, how the pores looked under function had been unknown. That is, until 1990 when Agre became the first to discover one. Chemical…

consumed by a portion of the plasma membrane. This results in the formation of a vesicle, or phagosome, which then fuses with a lysosome in the cytoplasm to break down and digest food particles. However, a large fraction of bacteria engulfed by protozoa are not digested. Instead, they remain metabolically active and survive to be discharged to the outside environment (Aijaz and Koudelka, 2017). The discharge of these indigestible materials occurs when the membrane of the phagosome reaches the…

and many other things ,but what am going to write about is a space ship.You may be thinking why a space, well a spaceship is as many functions that are very similar as the cells. The membrane is like the force field,because the force field protects the ship from intruders and the membrane protects the cell from anything wanting to get in. The nucleus is like the captain his the one in charge of what the spaceships does and also the crew members just like the nucleus is in control…

The cell wall is only found in plant, bacteria, fungi, algae and other archaea cells. Its main functions are to provide protection and support for the cell. But the cell wall has many other functions as well including intercellular communication, providing shape, they also regulate what gasses can enter each cell. The vacuole hold water in plant cells and the cell wall maintains shape when the vacuole is full. The cell wall also prevents the cell from bursting when the vacuole is fully expanded.…

semipermeable membranes. The purpose of Activity 3 is to explore how the size of a cell affects cell transportation. Background All cells are surrounded by a barrier called the cell membrane. It regulates what enters and leaves the cell, and also protects and supports the cell. Cell membranes are semipermeable, meaning it doesn’t allow all molecules to pass through it. For example, polar molecules and differently charged molecules are blocked from passing through the cell membrane, while…

The sodium-potassium pumps is a plasma membrane transport protein and serve to push an ion into a cell against its concentration gradient. This type of action is known as active transport because it needs the energy to be able to move the ions against their concentration gradient. Generally, the solutes being pushed in or out of a cell will go from a low concentration gradient to a high concentration gradient. The sodium-potassium pump is crucial to kidney function, nerve signaling, and heart…

I. Introduction Action potentials are generated as a result of a neuron’s membrane reaching a specific threshold. In order to reach this threshold, a cell must depolarize. Typically, cells depolarize with the opening of voltage-gated sodium channels. During the rising phase of the action potential, these channels allow positive sodium ions to flow into the cell in what is called the depolarization phase. The flow of these ions into the cell is often referred to as the sodium current. Once the…

Objectives Objective 1: Develop a cell line expressing the duck viperin. In order to develop an avian model that is able to express the duck viperin with an advantage of stable and homogeneous expression, duck viperin with and without the C-terminal V5 tag was previously cloned into the mammalian expression vector pcDNA3.1/Hygro+. Then, with the use of lipofectamine 2000, I stably transfected an empty vector and duck viperin tagged or untagged into DF-1 cells. In order to get a monoclonal…

One of the viruses that extend in massive areas of the world, and compel the scientists to look again for this virus is a ZIKA virus. As a result of the rapid prevalence of a ZIKA virus in Asia, Africa and America, it classifies now as an emerging virus, on the other hand, the lack of biological research leads to Increasing the cases of ZIKV in the world. This project sheds light on the mystery novel that allows ZIKV invasion and infection the host cells. A penetration process of ZIKA virus…
