Answer- a small uncharged molecule
A cell is having a lipid bilayer as a boundary. The cell membrane separates cellular content from surrounding.
The cell membrane is composed of lipids, proteins, and carbohydrates. Phospholipids are amphipathic molecules, have a hydrophilic head and hydrophobic fatty acid chains.
The small uncharged molecule can pass through lipid bilayer as they are soluble in the lipid bilayer. The large polar molecule cannot cross the lipid bilayer.
Please give a thumbs up!!!!!!!! Ask any doubts regarding the above question in the comment section !!!!!!!!!!! Thank you!!!!!
which is more likely to cross the plasma membrane, a small uncharged molecule or a large...
A small molecule that is lipid-soluble is likely to cross the cell membrane via? Osmosis, active transport, diffusion, facilitated diffusion, or group translocation?
Question 1 (1 point) Of the following, which type of molecule moves directly across a membrane at the slowest rate? Large polar molecules, such as glucose Proteins and other macromolecules Small, uncharged polar molecules, such as water lons, such as chloride (CI)
Question 11 (1 point) of the following, which type of molecule moves directly across a membrane most easily? Large polar molecules, such as glucose Small, uncharged non-polar molecules such as 02. lons, such as chloride (CI) Proteins and other macromolecules
Which of the following correctly describe(s) the normal structures and functions of the plasma membrane, described by the fluid mosaic model? A.The type of transmembrane protein complexes that a cell has in its membrane determine which materials can be shuttled in and out of the cell if they are polar or large. B.glycoproteins contribute to the identification of cells C.the selective permeability of the plasma membrane is a function of the phospholipid bilayer D.amino acids embedded in the bilayer...
12. Rank the following molecules in their ability to freely diffuse across the membrane (from 1- likely to 4- very unlikely) Large uncharged polar molecules, hydrophobic molecules, small uncharged polar molecules, ion.
what about the nucleosides? how could it cross the membrane? Q6: How would you expect nucleosides and steroids to cross the plasma membrane? And what are the requirements for compounds to pass through the membrane [20% Points] plasma * The el membrane is Selectively permeable; hydrophobic molecules and Small polar molecules can diffuse through the lipid Layer, but ions and Larg polar molecules Cannot. Integral membrane proteins enable ians and lary polar molecules to pass through by passive or active...
An uncharged molecule is at a concentration of 5.00 mM on the outside of a membrane and 4.00 uM on the inside. What is the potential energy change if a solute was allowed to move across the membrane by diffusion? (AG = RTin[X]ir/[X]out) Xout 5 or 0.0050 Xin 4x10-4 V AG= (0.008314). AG ?
Ions, polar molecules, and large molecules cannot readily cross a lipid bilayer and are dependent on transport proteins to cross a membrane. Classify each of the seven images as an example of a uniport, symport, or antiport transport system.
5. What is the free energy change in transporting an uncharged molecule across the membrane of a cell from 10 M to 10 M? Is an input of free energy required for this transport? (5 points) 6. What is the free energy cost of pumping Ca out of a cell when the cytoplasmic concentration is 0.9 uM, the extracellular concentration is 1.5 mM, and the membrane potential is -70mV at a temperature of 25°C? What is the free energy cost...
Question 1 Which of the following are likely to diffuse through the plasma membrane? glucose K+ Cl- H20 Na+ CO2 02 lipid Question 4 Which is(are) true about transport across the membrane? Channels can perform either active or passive transport Charged molecules move according to their electrochemical gradients Movement of an ion down its gradient requires energy Transporters are faster but less selective than channels Question 6 In the coupled transport of Na+ and glucose, the transporter O is an...
