例如，神經(jīng)鞘膜中脂類含量占75%，而蛋白質(zhì)只占18%，這利于膜在神經(jīng)興奮傳導中的絕緣作用；而線粒體膜蛋白質(zhì)含量占75%以上，脂類則占約20%，這與該膜含有豐富的酶有關。膜的功能越復雜，蛋白質(zhì)含量越高。膜中蛋白質(zhì)與脂類之比一般為4：1到1：4之間。生物膜的存在，不僅作為屏障為細胞的生命活動創(chuàng)造了穩(wěn)定的內(nèi)環(huán)境，介導了細胞與細胞、細胞與基質(zhì)之間的連接，而且還承擔了物質(zhì)轉(zhuǎn)運、信息的跨膜傳遞和能量轉(zhuǎn)換等功能，這些都是由生物膜的結(jié)構(gòu)決定的。
物質(zhì)運輸
生物膜因其半通透性而成為具有高度選擇性的通透屏障。細胞生長所需要的水、氧及其他營養(yǎng)物質(zhì)被運進細胞，細胞內(nèi)產(chǎn)生的激素、毒素和某些酶被運出細胞，細胞內(nèi)代謝產(chǎn)生的CO2、NH3等廢物被運出細胞，這些過程都與生物膜的物質(zhì)運輸機制有關。（1）被動運輸
被動運輸是小分子物質(zhì)和離子通過細胞膜的運輸機制之一，它不需要能量。
① 簡單擴散
像O2、N2、CO2和NO等氣體，類固醇激素等脂溶性小分子，水、甘油、尿素等不帶電的極性小分子均可經(jīng)此方式自由通過生物膜。這些物質(zhì)可由高濃度的一側(cè)通過膜向低濃度的一側(cè)擴散，這個過程或方式即簡單擴散。這種運輸方式的速率取決于被運輸物質(zhì)在膜兩側(cè)的濃度差，并zui后趨于達到擴散平衡。其特點在于不與膜上任何物質(zhì)發(fā)生反應，也不消耗能量。
一般來講，生物膜的電阻較高，不帶電荷的脂溶性物質(zhì)較易通過，即帶電荷或極性基團的親水物質(zhì)則不易自由通過，但上述幾種則例外。一般講，物質(zhì)在質(zhì)膜上的通透性主要取決于分子的大小和極性。小分子物質(zhì)比大分子物質(zhì)更易通過，非極性分子比極性分子更易通過。小的疏水分子和小的不帶電的極性分子能夠通過人工膜；水具有一定的透性，離子和大的不帶電的極性分子不能通過膜。
② 協(xié)助擴散
協(xié)助擴散是物質(zhì)借助膜上特異蛋白的幫助而從其濃度較高的一側(cè)通過膜運輸?shù)狡錆舛容^低的一側(cè)，直到兩邊濃度達到動態(tài)平衡的過程或方式，也不消耗能量。它也叫促進擴散或易化擴散。這里涉及的一般是膜的內(nèi)在蛋白，該蛋白通過其構(gòu)象變化而完成對物質(zhì)的運輸作用。這種運輸促進了擴散，并縮短了達到平衡所需的時間。根據(jù)這種運輸過程中運輸?shù)鞍椎墓ぷ魈攸c可做如下分類。

For example, the content of lipid in the nerve sheath accounts for 75%, while the protein accounts for only 18%, which is conducive to the insulation of the nerve conduction in the nerve membrane; and the mitochondrial membrane protein content accounted for more than 75%, lipid is about 20% This is related to the membrane-rich enzymes. The more complex the function of the membrane, the higher the protein content. The ratio of protein to lipid in the membrane is typically between 4: 1 and 1: 4. The existence of biomembrane not only serves as a barrier to create a stable internal environment for the life activities of cells, mediates the connection between cells and cells, cells and matrix, but also transports material, transmembrane transmission of information and energy conversion And other functions, these are determined by the structure of the biofilm.
Material transport
Biofilms are highly selective barrier to permeability due to their semipermeability. Water, oxygen and other nutrients needed for cell growth are transported into the cells. The intracellular hormones, toxins and certain enzymes are transported out of the cells. The CO2, NH3 and other wastes that are metabolized in the cells are transported out of the cells. These processes Biofilm with the material transport mechanism. (1) passive transport
Passive transport is one of the transport mechanisms for small molecules and ions through the cell membrane, which does not require energy.
① simple proliferation
Gas molecules such as O2, N2, CO2 and NO, fat-soluble small molecules such as steroid hormones, uncharged polar molecules such as water, glycerol and urea can all pass freely through the biofilm in this manner. These substances can diffuse from the high concentration side to the low concentration side through the membrane, which simply diffuses. The rate of this mode of transport depends on the concentration difference of the substance being transported on both sides of the membrane and finally tends to reach a diffusion equilibrium. It is characterized by not reacting with any substance on the membrane and consuming no energy.
In general, biofilms have higher electrical resistance, and uncharged lipophilic substances are easier to pass. Hydrophilic substances with charged or polar groups are not easily passed freely, except for the above. In general, the permeability of matter on the plasma membrane depends mainly on the size and polarity of the molecule. Small molecules are easier to pass than larger molecules, and non-polar molecules are easier to pass than polar molecules. Small hydrophobic molecules and small uncharged polar molecules can pass through the artificial membrane; water has a certain permeability, ions and large uncharged polar molecules can not pass through the membrane.
② to help spread
Assisted diffusion is the process by which matter is transported through the membrane from its higher concentration side to its lower concentration side with the help of specific proteins on the membrane until the concentration on both sides reaches the homeostasis and does not consume energy. It is also called promotion of diffusion or facilitation of diffusion. What is involved here is generally the membrane's intrinsic protein, which through its conformational change completes the transport of the substance. This transport has facilitated proliferation and has shortened the time it takes to reach equilibrium. According to the transport of transport proteins in the process of working characteristics can do the following classification.
