Cell function

Each component of blood has a function ia the body. Red cells transport oxygen and carbon dioxide between the lungs and cells ia the tissues. White cells function as defense of the body. Platelets are important for hemostasis, ie, the maintenance of vascular iategrity. Plasma, an aqueous solution containing various proteias and fatty acids, transports cells, food, and hormones throughout the body. Some proteias ia plasma play a role ia clotting, others are messengers between cells. [Pg.520]

In the fuel cell which has a high oxygen potential at one electrode, the cathode, and a low oxygen potential resulting from the oxidation of hydrocarbons at the anode, the cell functions as an oxygen transfer cell in which the reaction... [Pg.245]

Calcium channels in the plasma membrane activated after receptor-mediated calcium release from intracellular stores. Diese channels are present in many cellular types and play pivotal roles in a multitude of cell functions. It was recently shown that Orai proteins are the pore-forming subunit of CRAC channels. They are activated by STIM proteins that sense the Ca2+ content of the endoplasmic reticulum. [Pg.396]

Several agents affect the turnover of F-actin. They are not used therapeutically but serve as experimental tools to study the role of F-actin in cell function. [Pg.416]

Mitogen activated protein kinase (MARK) cascades are three kinase modules activated by phosphorylation. The three kinase modules are composed of a MAPK, a MAPKK, and a MAPKKK. There are multiple members of each component of the MAPK cascade that are conserved from yeast to human. Activation of selective MAPK modules by specific stimuli regulates cell functions such as gene expression, adhesion, migration, differ entiation, and apoptosis. [Pg.740]

Originally described in the immune system, NFAT proteins comprise a family of transcriptional factors that play key roles in many cellular processes that control not only immune responses but also the development, regulation, and differentiation of many other tissues. Activation of NFAT proteins results in the expression of specific sets of genes that regulate multiple cell functions [1,2]. [Pg.846]

Extrahypothalamic OX-B-like immunoreactivity, reminiscent to that of CRF, has been described in clustered GABAergic neuronal populations, in the lateral division of central nucleus ofthe amygdala, the bednucleus of the stria terminalis, and in the hippocampus. Moreover, ectopic expression of preproorexin mRNA in the gut, ependymal cells, neuroblastomas, and of orexin receptors in adrenal gland, cancer and hematopietic stem cells suggests yet unexplored roles of orexins as paracrine factors controlling blood-brain barrier, and tumor or stem cell function. [Pg.911]

P-site ligands inhibit adenylyl cyclases by a noncompetitive, dead-end- (post-transition-state) mechanism (cf. Fig. 6). Typically this is observed when reactions are conducted with Mn2+ or Mg2+ on forskolin- or hormone-activated adenylyl cyclases. However, under- some circumstances, uncompetitive inhibition has been noted. This is typically observed with enzyme that has been stably activated with GTPyS, with Mg2+ as cation. That this is the mechanism of P-site inhibition was most clearly demonstrated with expressed chimeric adenylyl cyclase studied by the reverse reaction. Under these conditions, inhibition by 2 -d-3 -AMP was competitive with cAMP. That is, the P-site is not a site per se, but rather an enzyme configuration and these ligands bind to the post-transition-state configuration from which product has left, but before the enzyme cycles to accept new substrate. Consequently, as post-transition-state inhibitors, P-site ligands are remarkably potent and specific inhibitors of adenylyl cyclases and have been used in many studies of tissue and cell function to suppress cAMP formation. [Pg.1038]

The total inapplicability of the Thomson rule to this case is at once apparent none of the electrical energy comes from chemical change, but the cell functions as a heat engine, converting the heat of its environment into electrical work. [Pg.463]

The antimetabolites interfere with various metabolic functions of cells, thereby disrupting normal cell functions. They inactivate enzymes or alter the structure of DNA, changing the DNA s ability to replicate These drag are most effective in the treatment of rapidly dividing neoplastic cells. Examples of the antimetabolites include methotrexate and fluorouracil (Adrucil). [Pg.592]

The composition of body fluids remains relatively constant despite the many demands placed on the body each day. On occasion, these demands cannot be met, and electrolytes and fluids must be given in an attempt to restore equilibrium. The solutions used in the management of body fluids discussed in this chapter include blood plasma, plasma protein fractions, protein substrates, energy substrates, plasma proteins, electrolytes, and miscellaneous replacement fluids. Electrolytes are electrically charged particles (ions) that are essential for normal cell function and are involved in various metabolic activities. This chapter discusses the use of electrolytes to replace one or more electrolytes that may be lost by the body. The last section of this chapter gives a brief overview of total parenteral nutrition (TPN). [Pg.633]

A student was given a standard Fe(s) Fe2+(aq) half-cell and another half-cell containing an unknown metal M immersed in 1.00 M MNO,(aq). When these two half-cells were connected at 25°C, the complete cell functioned as a galvanic cell with E = +1.24 V. The reaction was allowed to continue overnight and the two electrodes were weighed. The iron electrode was found to be lighter and the unknown metal electrode was heavier. What is the standard potential of the unknown MT/M couple ... [Pg.642]

A voltaic cell functions only when the electrical circuit is complete. In the external circuit the current is carried by the flow of electrons through a metal wire. Explain how the current is carried through the cell itself. [Pg.646]
