Cell Biology Exam 1 Notes Lecture 1: Introduction to Cell Biology • Biology is studied at different levels of organization Time Scale • [Figure 1-9] How big is a cell and how big are its parts? • There are important similarities that all cells share; however‚ there are also important differences among various cell types (for example‚ animal cells vs. bacterial cells) • [Figure 3-23] The inside of a cell is loaded (crowded

functions of the main cell components of the body cell. The cell membrane : is something that lets some things in and some things out of the cell. It is an outer cover for the cell. If the cell membrane was non existences the cell would spill all over the place. Its function is to protect the integrity of the interior of the cell by allowing certain substances into the cell‚ while keeping other substances out. It is composed of a thin‚ double-layered sheet of lipids‚ around the Cell and is a protective

Cell Phones in the Hands of Drivers A Risk or a Benefit Ariana Laguna English 102 Professor Barnes/Walter 10 December 2012 Outline THESIS: Unless the risks of cell phones are shown to outweigh the benefits‚ we should not restrict their use in moving vehicles: instead‚ we should educate the public about the dangers of driving while phoning and prosecute irresponsible phone users under laws on negligent and reckless driving. I. Scientific studies haven’t proved a link between use of

Carbohydrates There are four different types of carbohydrates which are saccharides‚ starch‚ NSP’s and sugar substitute. Saccharides Saccharides are soluble in water. A simple sugar is monosaccharide which is easily absorbed by the body. The type of saccharides sugars are fructose‚ glucose and lactose. No more than 11% of an adult’s sugar should be sugar Food sources that saccharides can be found white bread energy drink biscuits chocolate sweets Starch

Lab Report 1: Subculturing Adherent Cells Fibronectin‚ integrin alpha 3‚ and actin are all involved in cellular adhesion at both the cellular and molecular levels. Integrins are the primary trans-membrane receptors that mediate dynamic interactions between the extracellular matrix and the actin cytoskeleton whenever a cell is motile. Integrins bind to the extracellular matrix and link to the actin cytoskeleton via a shirt cytoplasmic tail; they also help determine cellular binding specificity because

Our cars are so advanced that they pretty much drive themselves and even the devices in our kitchen can prepare a scrumptious supper with minimal input from our side. I recall when cell-phones were announced the very first time. I have to confess that I was still quite young and foolish at that stage and did not quite understand what the fuss was about. Buddies of

Explain. Every cell contains organelles‚ the structures that carry out their specific functions. Organelles are also known as cell compartments. Eukaryotic cells have membrane bound compartments in which specific metabolic activities takes place. The organelles of the prokaryotes are not membrane bound and are simpler structures. Just like organs‚ each organelle contributes in its own way to help the cell function well as a whole. The organelles are endoplasmic reticulum‚ golgi apparatus‚ mitochondrian
