Microfibrils

... of a plant cell for it's wall to stretch. In fact that is how the shape of a cell is determined: the cell wall in the young cell has microfibrils oriented in a particular fashion so that when the cell accumulates water the cell wall will stretch in a particular way giving the cell ...

... to an increase in volume. The cell wall will stretch, but of course it is a directed stretch, dictated by the number of bonds between cellulose microfibrils and the orientation of the microfibrils. Unfortunately it is too much too explain here. Look up molecular mechanism of auxin and giberelins, ...

... by the inability of enzymes to access additional substrate . This is likely to be due in part to most cellulose chains being buried within the microfibrils. Moreover, coverage of some surface chains by the "footprint" of enzyme molecules (particularly those in a complexed form) that ...

... evidence, to our knowledge, of the presence of cellulose in these organisms. Based on the results of x-ray diffraction, electron microscopy of microfibrils, and cellobiohydrolase I-gold labeling, we report the occurrence of cellulose biosynthesis in nine species representing three of the five ...

... that these aggregates are a component of the cellulose synthethase complex (E. SCHNEPF,1986). The rosettes are thought to spin out cellulose microfibrils while moving through the plant plasma membrane. The diagram is simplified in that about six cellulose polymers must emerge in association ...
