Area of the cell | Function of the cell | Cell-Cells are the basic building blocks of all living things. They provide structure for the body, and also take in nutrients from food and convert those nutrients into energy and carry out specialized functions. | In the human cell, firstly we have the red blood cells; these carry oxygen around the body from our lungs, to the rest of our body. The nerve cells carry nerve impulses to different parts of the body which carry electrical signals around the

flavor, an attractive color and clarity. To attain these characteristics, Membrane separation technology has become widely used in the food processing industry. The final filtration stage sets for a balance between allowing the passage of dissolved macromolecules that give the beer its flavor and functional properties while removing yeast cells and turbidity colloids and reducing the components that cause turbidity of the bottled beer. Moreover the potential of cross-flow microfiltration as a separation

Introduction Centrifugation is a process used to separate or concentrate materials suspended in a liquid medium. The theoretical basis of this technique is the effect of gravity on particles (including macromolecules) in suspension. Two particles of different masses will settle in a tube at different rates in response to gravity. Centrifugal force (measured as xg, times gravity) is used to increase this settling rate in an instrument called a centrifuge. Centrifuges are devices used in a variety

Gel electrophoresis Gel electrophoresis is a method for separation and analysis of macromolecules (DNA, RNA and proteins) and their fragments, based on their size and charge. It is used in clinical chemistry to separate proteins by charge and/or size (IEF agarose, essentially size independent) and in biochemistry and molecular biology to separate a mixed population of DNA and RNA fragments by length, to estimate the size of DNA and RNA fragments or to separate proteins by charge.[1] Nucleic acid

Lab: 3—Chemical Composition of Cells: Sugars Purpose of this lab: To learn about sugars and the test used to identify them. Introduction The organic macromolecules known as sugars are a type of carbohydrate. Carbohydrates are composed of monosaccharides, which are single, sugar unit monomers. Two sugar units linked together are known as a disaccharide. In this lab, we conducted tests on various substances with Bendict’s solution to determine which sample contained sugars.

deformation of an elastic solid and the phenomenon of viscoelasticity. This is a topic of special interest in the study of structural biomolecules such as bone and blood vessels. We conclude the chapter with a discussion of the structure and dynamics of macromolecules, specifically illustrating how to apply Newton’s second law to the difficult problem of determining the molecular motions (here in one dimension) of the constituent atoms of a protein. 1. THE CONSTANT FORCE Very frequently in dealing with
