Schematic representation of types

FIGURE 18.5 Schematic representation of types of multienzyme systems carrying out a metabolic pathway (a) Physically separate, soluble enzymes with diffusing intermediates, (b) A multienzyme complex. Substrate enters the complex, becomes covalently bound and then sequentially modified by enzymes Ei to E5 before product is released. No intermediates are free to diffuse away, (c) A membrane-bound multienzyme system. 

Fig. 9.5 Schematic representation of Type-I intermittency. The plot on the LHS shows a return map for the system as it appears just below and precisely at the critical parameter value Tc. The plot on the RHS shows the return map for r > r. Note how, for r > Vc, X = Xc appears to first attract" then repel trajectories.

Figure 32.9. Schematic representation of Type I hypersensitivity. Induction Resident respiratory tract dendritic cells (DC) take and process antigen, mature, migrate to the draining lymph nodes, and present antigen to T lymphocytes. Activated T-lymphocytes, in turn, activate B-cell differentiation into antibody-producing plasma cells. IL-4 promotes Ig isotype class switching from IgM to IgE and promotes mast cell development. IgE is associated with mast cells. Elicitation Allergen crosslinks the mast-cell-bound IgE, thereby causing the release of preformed mediators and cytokines. (See Table 32.7.) Inflammation and bronchoconstriction occur.

A schematic representation of type-I ternary phase behavior is shown in figure 3.29. The three diagrams in this figure represent mixtures at a fixed temperature slightly higher than the critical temperature of the SCF but at three different pressures. The distinguishing feature of type-I ternary phase behavior is the absence of LLV immiscibility regions within the ternary...

Figure Bl.20.9. Schematic representation of DLVO-type forces measured between two mica surfaces in aqueous solutions of KNO3 or KCl at various concentrations. The inset reveals the existence of oscillatory and monotonic structural forces, of which the latter clearly depend on the salt concentration. Reproduced with pennission from [94].

We have seen (Section I) that there are two types of loops that are phase inverting upon completing a round hip an i one and an ip one. A schematic representation of these loops is shown in Figure 10. The other two options, p and i p loops do not contain a conical intersection. Let us assume that A is the reactant, B the desired product, and C the third anchor. In an ip loop, any one of the three reaction may be the phase-inverting one, including the B C one. Thus, the A B reaction may be phase preserving, and still B may be attainable by a photochemical reaction. This is in apparent contradiction with predictions based on the Woodward-Hoffmann rules (see Section Vni). The different options are summarized in Figure 11.

Several human receptors for the neurohypophyseal hormones have been cloned and the sequences elucidated. The human V2 receptor for antidiuretic hormone presumably contains 371 amino acids and seven transmembrane segments and activates cycHc AMP (76). The oxytocin receptor is a classic G-protein-coupled type of receptor with a proposed membrane topography also involving seven transmembrane components (84). A schematic representation of the oxytocin receptor stmcture within the membrane is shown in Eigure 4 (85).

The electrical Itw-pressure impactor (ELPl) has been developed, using the Berner-type multijet low-pressure impactor stages. The cut sizes of the seven channel system range from 0.030 to 1.0 pm. Real-time measurements can be achieved due to the instrument s fast time response. The schematic representation of the impactor construction is shown in Fig 13.44. 

Figure 3.11 Schematic representation of the energy levels in various types of 3-centre bond. The B-H-B ( electron deficient ) bond is non-linear, the ( electron excess ) F-Xe-F bond is linear, and the A-H B hydrogen bond can be either linear or non-linear depending on the compound.

Schematic representation of defect clusters in Fei- jO. The normal NaCl-type structure (a) has Fe (small open circles) and O (large dark circles) at alternate comers of the cube. In the 4 1 cluster (h), four octahedral Fe" sites are left vacant and an Fe" ion (grey) occupies the cube centre, thus being tetrahedrally coordinated by the 40. In (c) a more extended 13 4 cluster is shown in which, again, all anion sites are occupied but the 13 octahedral Fe sites are vacant and four Fe occupy a tetrahedral array of cube centres.

Figure 48-3. Schematic representation of fibronectin. Seven functional domains of fibronectin are represented two different types of domain for heparin, cell-binding, and fibrin are shown. The domains are composed of various combinations of three structural motifs (I, II, and III), not depicted in the figure. Also not shown is the fact that fibronectin is a dimer joined by disulfide bridges near the carboxyl terminals of the monomers. The approximate location of the RGD sequence of fibronectin, which interacts with a variety of fibronectin integrin receptors on cell surfaces, is indicated by the arrow.

[Other glyco-sphingolipids fragment in a similar way. Major cleavages are shown with solid lines, and minor cleavages with dotted lines. The masses of ions resulting from cleavages (a), (b), and (c) define the type of sphingosine and the type of fatty acid.
