Biological Membrane Study: HCl‚ NaOH‚ SDS Objective and Hypothesis: The objective of this lab is to determine the effects of SDS‚ HCl‚ and NaOH on red cabbage cell membrane. Prior knowledge can tell us that the red cabbage is a red-purple color due to a pigment called anthocyanin. This is what we will be testing in the experiment. We also know that HCl is a strong acid (very low pH) and that NaOH is a strong base (very high pH). From information learned in this course (lecture/lab) we can assume

For instance‚ Genesis One and The World’s Biggest Membrane describe an ongoing process of creation. It is clear in Genesis One that God did not get it right the first time. After creating man God thinks‚ “It is not good for the man to be alone. I will make a helper suitable for him.” (2:18-19) Immediately

structure of the plasma membrane and explain the process of active and passive transport through the membrane. The plasma membrane is made up of proteins that form pores and channels‚ carbohydrate molecules that are used for cell recognition and cholesterol to provide membrane stability. Phospholipid molecules are the most abundant component found in the plasma membrane. Phospholipids molecules are composed of a phosphate head and a lipid tail; the structure of a cell membrane is a double layer

1. The cell membrane structure is vital to the life of the cell. The cell membrane is shaped as having a phosphate head at the very outer surface‚ and two fatty acid tails hanging from it. The membrane is double‚ so at the tip of the fatty acid tails‚ there are two more fatty acid tails attached to another phosphate head. This is what it looks like: <br> <br>The reason the cell membrane is shaped like this is mainly to control the water flow in and out of the cell. Water is very important to

electrically excitable membrane changes its electric potential. In other words‚ how is the cell membrane excited? At the surface of the cell membrane‚ there are three classes of gated channels exist‚ chemically gated or ligand-gated channels‚ voltage-gated channels‚ and mechanically gated channels. Originally‚ at the resting membrane potential‚ most of the gated channels are closed. However‚ when these gated channels open‚ the movement of ions across the membrane will changes the membrane potential. In the

chemical known today as ethanol) in the 18th century and was extended to the class of substances so-called as "alcohols" in modern chemistry after 1850. The first alcohol (today known as ethyl alcohol) was discovered by the tenth-century Persian alchemist al-Razi. The current Arabic name for alcohol (ethanol) is “al-ġawl” – properly meaning "spirit" or "demon" – with the sense "the thing that gives the wine its headiness" (in the Qur’an sura 37 verse 47). The term “ethanol” was invented 1838‚ modeled
