Crystals with large active faces have a large contact area with epithelial cell surface, and crystals with sharp edges can easily scratch epithelial cells; these factors could promote crystal adhesion and aggregation, thus increasing stone risk....
TRANSPORT OF WATER AND SALTS THROUGH PLANT TISSUES The cellular mechanism of active transport of water and salts is probably similar in plants and animals ; but plants are in several respects more ... H Lundegardh - 《Nature》 被引量: 0发表: 0年 Water transport across mammalian cell membrane...
Tumor cells may develop resistance to an antifolate drug by virtue of, (1) amplified activity in its target enzyme, (2) impaired function of drug transport protein, e.g. reduced folate carrier (RFC), (3) induction of mutated target enzyme with low affinity for antifolate(s), and (4) ...
Calcium supply for calcification is diffusional through oral layers, and active membrane transport only occurs between the calicoblastic cells and the site of calcification. Photosynthesis and calcification are tightly coupled in zooxanthellate scleractinian corals and coral reef communities. Calcification is...
Once membrane bound, either the protonated LCFA diffuses across the membrane bilayer or the ionized (or possibly the protonated) LCFA may bind to LCFA translocase proteins for transbilayer transport (see Step 6). Step 4. Entry of extracellular free long chain fatty acid into the cell membrane:...
