Facilitated Diffusion Eg Glycrol Molecule, H2O,W2 Once the solute binds the conformational change happens here. Solute binding Sites Present in the Camer molecule. Rate of transport is enhanced. Active transport a) ATP Carette Protein ABC- ATP binding error Sulute binding protein and transporter protein Transporter Protein - ATP binding Protein. (ATP binding domain/ Nucleoticle binding domain) Solute binding protein bind to solute and brings to transporter prote ATP binds to ATP binding domain and gets hydrolyzed ATP Apptip.). phosphorous facilitates the entry of the Solute b) Proton Motive Force look e trange NADP larrier molecule O2. chair) e hanger chain (series of). During e transport the protony will be Pumbed out of cell (Periplain So Proton gradient occurs 3 Propoin Proton - \ ATP.
- Proton gradient drives Sodium ion expulsin by an antiport mechanism Ht moves out Uniport Steps 1 Protons are pumbed to the outside of the plasma membrane. during e transport 2 The Proton gradient drives Sodium inn expulsion byan an antport mechanism 3 Sodium binds to the carrier poten complex. 4 The shape of the Solute binding site change and it bind the solute eg. sugar (aminoacid . 5 The carrier's conformation then alter $0 that sodium is released on the inside of the membrane. Then is followed by solute dissounction from the carrier (sympart mechanism). PTS Transport (.g. works in E.coli). Also called Group translaction. PEP-higherang mulecule PTS - phosenol Pynevate Sugar polyp transferace system. - Gucose taken Inside after modification. b - High energy molecule like PEP required to give phosphorous phosphothersferae helps Do the PEP to release phosphonous and. gre
Enzyme I ,11, 111 present for Phorphotransforase. Enzyme A - freely suspended. B haryboar 11c Attached Hpr Histidine rich Protein - helps in translocation Glucose enters through 11C. Mannitol mannose can also be transported using this. Module Eukergotin tion uptake Iron Uptake Setal Because of solubility Iron is difficult to transport Siderophore are used. for the transport of Iron Catecholites actually. Examples of Sidenphore - ferratroma enterobaitin. Siderophores binds to Fc molecule 00/01/19 Iron moleant secrete Sideopha - Recepton are present for siderophores in the membre. ie receptors Complex formed ag. enterobacth - Iron comple (ie, Siderophoe complex) The complex binds to receptors and then taken to periplasmic space (ie, femic to ferrous occurs and then taken Inside) enzyme helps in this conversion
