‘Discuss how cell organelles are structurally and functionally interrelated’ The Golgi body is a membrane bound organelle mainly found in eukaryotic cells. The Golgi body has two faces the cis face‚ where the substances enter from the RER for processing and the trans face‚ where they exit the RER in the form of tiny vesicles. (Davidson‚ M. (2004) Molecular expressions http://micro.magnet.fsu.edu/cells/golgi/golgiapparatus.html) The rough endoplasmic reticulum is the site where most cell membrane

How to Calculate Beta Beta refers to the volatility of a particular stock compared against the volatility of the entire stock market or‚ in practice‚ a representative index of that market‚ such as the Standard and Poor ’s (S&P) 500. Beta is an indicator of how risky a particular stock is and is used to evaluate its expected rate of return. Beta is one of the fundamentals stock analysts consider when choosing stocks for their portfolios‚ along with price-to-earnings ratio‚ shareholder ’s equity

Cell Processes and Body Organisation Nucleus The nucleus is the largest‚ most prominent organelle‚ usually spherical and roughly about 10mm in diameter. Every eukaryote cell‚ with the exception of red blood cells due to their very specific function‚ has a nucleus. The nucleus’ function is to store DNA‚ it does so in two ways: One is tightly packed and this is called heterochromatin‚ this isn’t read. And the other is loosely packed‚ named euchromatin. Euchromatin is the actively read material

How insulin effects digestion Insulin is a hormone that is produced in specialized cells in the islets of Langerhans‚ a part of the pancreas. The main role of insulin is to regulate the body’s use of sugars and other nutrients. The process is initiated during and immediately after the process of digestion breaks down carbohydrates into sugar molecules (including glucose) and proteins into amino acids. Right after a meal‚ glucose and amino acids are absorbed directly into the bloodstream

Question: Describe five different organelles and their functions. Explain the similarity and differences between eukaryotic cells and prokaryotic. All eukaryotic cells‚ whether from animals‚ plants‚ protists‚ and fungi‚ are fundamentally similar to one another but different from prokaryotic cell. A eukaryotic cell contains various other organelles‚ which perform specific functions in the cell. These organelles can be organized into few basic functional groups such as genetic control‚ distribution

How Cell Phones Work Cell phones are very interesting! Have you ever wondered how a cell phone works? Well we have. Cell phones have changed a lot since 1984. The first cell phone that came out was called the Dyna TAC8000X. (top left) It weighed 2 pounds! The brick only offered a half-hour of talk time for every charge. You could get this amazing device for $3‚994! The man who invented this phone is Ruby Knopp. (top left) He also invented the newer modern Motorola Razor. (top middle) Some of
