Uniporters - Study guides, Class notes & Summaries

Microbiology Exam 2 UTA; Questions and Answers % Correct Uniporters Correct answer-Transport in one direction across the membrane Symporters Correct answer-Functions as co-transporters; the two molecules travel in the same direction; 1. Energy is released as one substituent moves down its concentration gradient 2. This energy moves a second substrate against its gradient into the cell

BIO 213 EXAM 3 GMU LATEST UPDATE 100% PASS active transport energy required Active transport moves substances across a concentration gradient, requires energy, involves uniporters, symporters, and antiporters Antoni Van Leeuwenhek discovered microbial world using a simple lens apical membrane faces the lumen of outside of the body Autocrine signals diffuse to and affect the cells that make them ex: is a tumor cell autophagy lysosomes digest cell material basolateral memb...

bulk transport involves packaging of large molecules exocytosis secretion of large molecules via bulk transport "bulk secretion" endocytosis intake of large molecules via bulk transport "bulk uptake" Primary Active Transport active transport that utilities ATPs directly to move molecules Secondary Active Transport active transport that utilizes a pre-existing gradient flow to move molecules carrier proteins proteins that are known as transporters--undergo a 3D change, bind solute on one...

Membrane Transport What is the major difference between V-ATPase and F-ATPase? - ANSWERSV-ATPase uses ATP to pump hydrogen against the concentration gradient; F-ATPase uses hydrogen concentration gradient to make ATP Why can't H3O+ flow through an aquaporin channel? - ANSWERSH3O+ size and charge; positively charged Asn repel H3O+ How would F-ATPase be affected with H3O+ could flow through aquaporins? - ANSWERSChange H+ gradient, affecting function of F-ATPase and production of ATP How...

_______________ have a single or multiple solute binding pockets and after solute binding, a reversible conformation movement exposes the solute-binding pocket to the other face of the membrane. - transporters Because of the factors affecting diffusion, H2O will move from an area of higher concentration (low osmolarity) to an area of lower concentration (higher osmolarity) if the cell membrane is permeable to H2O [6.03]. The movement of H2O in this way is a very powerful force, capable of r...
