Answer: C(CO2)
Some of the uncharged such as O2 and CO2 pass through the lipid bilayer and as the concentration is more outside so it can easily cross the membrane by diffusion i.e from higher concentration to lower concentration.
Which of the following substances is most likely to enter a cell by diffusing directly through...

Question 24 Which of the following categories of membrane proteins is most likely to have restricted lateral mobility in a membrane? enzyme transporter O anchor O receptor all are restricted Question 5 New membrane synthesis occurs by spontaneous aggregation of free phospholipids into a new bilayer incorporation of phospholipids into one face of a preexisting membrane and their specific redistribution by enzymes like flippases incorporation of phospholipids into both faces of a preexisting membrane at the same time formation of...
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...
