The integral membrane proteins called transporters that mediate movement of molecules across a membrane by diffusion. In order to achieve such movement, a solute (molecule to be transported) binds to a specific site on a transporter (large peptide) on one surface of the membrane. The transporter then changes shape in order to expose the bound solute to the opposite side of the membrane. The solute then dissociates from the transporter and reached on the other side of where it started. There are various types of transporter having specific binding sites which bind specific substances depending on the membrane and the need of cellular environment.

Secreted or membrane-bound proteases can provide another simple, yet effective resistance strategy against antimicrobial peptides, by effectively cleaving and inactivating them. why nowadays ,many antimicrobial peptides still can be used in the antimicrobial area and as a novel drug to kill bacterila? and the antimicrobial peptides how to avoid the proteases to inactivating it???
Molecule A is rapidly consumed by cells. Membrane Protein A is a carrier protein that allows molecule A to move across a cell membrane. How would inhibiting the expression of the gene that codes for Membrane Protein A affect intracellular and extracellular concentrations of molecule A?
Question 2 Which of the following best describes how both symport and antiport transporters move two different types of molecules? They move two molecule types down both of their electrochemical gradients. They move two molecule types up both of their electrochemical gradients. They move one molecule type up and one down their electrochemical gradients. They move two molecule types into the cytosol. They move two molecule types out of the cell. They use ATP to power active transport. Question 3...
How can a signaling molecule be interpreted in different ways by cells in the body?
In accomplishing facilitated diffusion in living cells: Group of answer choices no ATP is required move particles down a concentration gradient move large or impermeable particles move particles using integral proteins all of these
Cars A and B move in the same direction in adjacent lanes. The position of car A is given in the figure. At t=0, car B is at x=0, with a velocity of 10 m/s and a negative acceleration. What must be that acceleration such that the cars arc side by side when t=6 sec? For that value of the acceleration, how many times will the cars be side by side?
