跨膜梯度 的英文怎麼說
中文拼音 [kuàmótīdù]
跨膜梯度
英文
transmembrane gradient-
Xanthophyli cycle has been widely concerned since the finding that it has the function in heat dissipation. with the trans - thylakoid ph gradient, zeaxanthin ( z ) together with antheraxanthin ( a ) can absorb excess energy from chlorophyll and release it as heat, thus protect the photosynthetic apparatus from photodamage by high light. violaxathin de - epoxidase ( vde ) is the key enzyme in xanthophylls cycle
目前普遍認為葉黃素循環的色素定位於天線色素蛋白復合體上，在跨膜質子梯度（ ph ）形成后，玉米黃質（ z ）和環氧玉米黃質（ a ）能夠從葉綠素中吸收過多的激發能，並以熱能的形式耗散到體外，從而保護光合器官免受強光的破壞。Pcr analysis indicated that all lines had been integrated of ssmapkk. northern analysis revealed the presence of expression of ssmapkk mrna in transgenic lines. in principle, ssvp overexpression can increase proton electrochemical gradients across the vacuolar membranes, which permit the secondary active transport of na + and solute molecules
理論上， ssop的過量表達可增加轉基因植株細胞跨液泡膜的質子電化學梯度，為次級轉運提供驅動力，從而增加可溶性物質和na十向液泡內的轉運，提高轉基因植株的抗旱和抗鹽性。Facilitated diffusion a passive transport of molecules across a cell membrane along a concentration gradient, mediated by carrier molecules or complexes, usually proteins
易化擴散（促進擴散） ：分子沿濃度梯度由載體分子或復合物（通常是蛋白質）作為媒介的一種被動跨膜運輸。Active transport the transport of molecules or ions across a cell membrane against a concentration gradient, with the expenditure of energy, usually in the form of atp
主動運輸：伴隨著能量的消耗， atp的產生，逆著濃度梯度的分子或者離子的跨膜運輸。分享友人
