(PTS2). In a normal cell‚ the Pex7p receptor has a PTS2 receptor region that recognizes and binds the PTS2 of the localized protein in the cytosol‚ necessary for transport into the peroxisome (Braverman et al. 1993). Pex7p receptor works in conjunction with Pex5p receptor‚ which equivalently recognizes peroxisome-targeting signal 1 (PTS1) on the C-terminal domain of proteins. Once the mobile cytosolic import

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

SDS-PAGE is to separate peptide chains in a protein sample according to molecular weight by sieving them through a gel matrix under the influence of an electric current. The setup for an SDS-PAGE experiment is shown in Figure 1.0 [pic] Figure 1.0- An illustration of a simple SDS-PAGE setup Based on the figure above it can be observed that big proteins (high MW) travel a shorter distance than that of smaller proteins (low MW). This is because bigger proteins have a difficult time in traversing through

BIOMOLECULES 1.What are macromolecules? Give examples. Macromolecules are large complex molecules that occur in colloidal state in intercellular fluid. They are formed by the polymerization of low molecular weight micromolecules. Polysaccharides‚ proteins‚ and nucleic acids are common examples of macromolecules. 2. Illustrate a glycosidic‚ peptide and a phospho-diester bond. (a) Glycosidic bond is formed normally between carbon atoms‚ 1 and 4‚ of neighbouring monosaccharide units. (b) Peptide
