The carrier protein transports large molecules like amino acids and glucose from high concentration to low concentration. We used modeling clay with a large gap to show the large molecules are transported between through the carrier protein.

1. Define the terms anatomy and physiology. Explain the principle of complementarity and how it applies to this course. The term anatomy refers to the structure of the body and its parts. Along with the study of the body structure‚ anatomy also refers to how these body parts work together and their working relationship as a whole. Physiology is the study of how the living systems in the body function and work. When studying the Physiology of the body it is most understandable if terms from the underlying

Polymers-the largest of the macromolecules. These are composed of numerous‚ small identical subunits known as Monomers. There are 4 major polymers that are important for living organisms. These polymers are; carbohydrates‚ lipids‚ proteins and nucleic acids. B. Polymers are referred to as being organic compounds. Organic compounds are compounds that contain the elements carbon and hydrogen. 1. Chemical Properties of Carbon a. Carbon has 6 electrons. What is the structure

classic first step to fractionate proteins by causing perturbations in the solvent with respect to ionic strength. Historically‚ separation methods were limited and as a result precipitation methods were highly used with very fine cuts in ppt conditions. As more choices of inexpensive and quality resins are commercially available precipitation steps are typically limited to one or two initial cuts in the beginning of purification or simply used to concentrate the proteins. The major advantage to (NH4)2SO4

small percentage of familial forms of the disease. The following discoveries were the mutations in the genes for FUS ans TARDBP (encoding for TDP-43 protein). Neuropathological analysis led to the identification of insoluble cytoplasmic phosphorylated protein deposits in brain and spinal cord. TDP-43 is a broadly expressed and highly conserved protein with different functions in RNA metabolism‚ including RNA translation‚ splicing and transport. In physiological conditions‚ TDP-43 is located in de

of a mosaic of proteins imbedded into a bilayer of phospholipids. Phospholipids obtain the ability to form membranes because of the fact that it is an amphipathic molecule. This means it contains polar hydrophilic heads and nonpolar hydrophobic tails‚ which make up the hydrophilic and hydrophobic regions of the membrane. The two types of proteins found in the fluid-mosaic model are integral proteins‚ which go through the hydrophobic core of the lipid bilayer‚ and peripheral proteins‚ which are appendages

Protein purification From Wikipedia‚ the free encyclopedia Jump to: navigation‚ search Protein purification is a series of processes intended to isolate a single type of protein from a complex mixture. Protein purification is vital for the characterization of the function‚ structure and interactions of the protein of interest. The starting material is usually a biological tissue or a microbial culture. The various steps in the purification process may free the protein from a matrix that confines

Biology Assignment (Haemoglobin) Proteins are large‚ complex molecules that are made up of hundreds or thousands of smaller units called amino acids‚ which are attached to one another in long chains. There are 20 different types of amino acids that can be combined to make a protein. The sequence of amino acids determines each proteins unique structure and specific function. They play many critical roles in the cells. They can be grouped as enzymes‚ antibodies‚ messengers‚ structural components or
