這些細胞形狀的多樣性都是細胞形態(tài)與其功能相適應的結果。
一般講來,植物細胞的體積很小,多數(shù)細胞的直徑為10~100μm,肉眼難以辨別。有人認為:細胞體積的大小,主要受細胞核所能控制的范圍的制約,體積小,則表面積大,有利于細胞與外界進行物質交換。但不同種類、不同部位的細胞大小差別懸殊。
分內在蛋白和外在蛋白兩種。內在蛋白以疏水的部分直接與磷脂的疏水部分共價結合,兩端帶有極性,貫穿膜的內外;外在蛋白以非共價鍵結合在固有蛋白的外端上,或結合在磷脂分子的親水頭上。如載體、特異受體、酶、表面抗原。占20%~30%的表面蛋白質(外周蛋白質)以帶電的氨基酸或基團——極性基團與膜兩側的脂質結合;占70%~80%的結合蛋白質(內在蛋白質)通過一個或幾個疏水的α-螺旋(20~30個疏水氨基酸吸收而形成,每圈3.6個氨基酸殘基,相當于膜厚度。相鄰的α-螺旋以膜內、外兩側直鏈肽連接)即膜內疏水羥基與脂質分子結合。理論上,鑲嵌在脂質層中的蛋白質是可以橫向漂浮移位的,因而該是隨機分布的;可實際存在著的有區(qū)域性的分布;(這可能與膜內側的細胞骨架存在對某種蛋白質分子局限作用有關),以實現(xiàn)其特殊的功能:細胞與環(huán)境的物質、能量和信息交換等。(Frye和Edidin1970年用發(fā)紅光的堿性芯香紅標記人細胞同用發(fā)綠光熒光素標記膜蛋白抗體標記離體培養(yǎng)的小鼠細胞一起培養(yǎng),然后使它們融合,從各自分布,經(jīng)過37℃40min后變?yōu)榫鶆蚍植肌9庵缕谉晒饣謴头?,微區(qū)監(jiān)測)
細胞膜上存在兩類主要的轉運蛋白,即:載體蛋白(carrier protein)和通道蛋白(channel protein)。載體蛋白又稱做載體(carrier)、通透酶(permease)和轉運器(transporter),能夠與特定溶質結合,通過自身構象的變化,將與它結合的溶質轉移到膜的另一側,載體蛋白有的需要能量驅動,如:各類ATP驅動的離子泵;有的則不需要能量,以協(xié)助擴散的方式運輸物質,如:纈氨酶素。通道蛋白與與所轉運物質的結合較弱,它能形成親水的通道,當通道打開時能允許特定的溶質通過,所有通道蛋白均以協(xié)助擴散的方式運輸溶質。
The diversity of these cell shapes is the result of the adaptation of the cell morphology to its function.
In general, the volume of plant cells is very small, the majority of cells with a diameter of 10 ~ 100μm, the naked eye is difficult to distinguish. Some people think: the size of the cell volume, mainly controlled by the scope of the cell nucleus constraints, small size, the surface area is large, is conducive to cell exchange with the outside world. But different types, different parts of the cell size difference.
Divide the intrinsic protein and exogenous protein two kinds. The intrinsic protein is covalently bound directly to the hydrophobic portion of the phospholipid in a hydrophobic moiety and has polarities at both ends that penetrate both inside and outside the membrane; extrinsic proteins bind non-covalently to the outer ends of the native proteins or to phospholipid molecules Hydrophilic head. Such as carriers, specific receptors, enzymes, surface antigens. 20 to 30% of surface proteins (periplasmic proteins) are bound to lipids on both sides of the membrane with charged amino acids or group-polar groups; 70 to 80% of bound proteins (intrinsic proteins) Or several hydrophobic α-helices (20 to 30 hydrophobic amino acids, 3.6 amino acids per circle, equivalent to the membrane thickness. The adjacent α-helices are linked by linear peptide in the membrane and on the outside) That is, the hydrophobic hydroxyl in the membrane binds to lipid molecules. Theoretically, the proteins embedded in the lipid layer are laterally floating and displaceable, and thus they are randomly distributed; there may actually be a regional distribution (this may be related to the presence of a cytoskeleton on the inside of the membrane Protein molecular constraints related to), in order to achieve its special function: the cell and the environment of the material, energy and information exchange.

There are two main types of transporters on the cell membrane: carrier protein and channel protein. Carrier proteins, also known as carriers, permease and transporters, are capable of binding to specific solutes and transferring the solute bound thereto to the other side of the membrane by a change in self-conformation, Some proteins need energy-driven, such as: all kinds of ATP-driven ion pump; while others do not need energy to facilitate the proliferation of transport substances, such as: valsamin. The channel protein binds weakly to the transported substance, it forms a hydrophilic channel that allows specific solutes to pass when the channel is open, and all channel proteins transport the solute in a manner that assists diffusion.
