Source sentences:
text: With these specialized proteins, the cell membrane becomes a selectively permeable membrane, as the genetics of the cell decide which molecules can pass the membrane.
text: Very small molecules, such as gaseous oxygen (O 2 ), gaseous carbon dioxide (CO 2 ), and water (H 2 O), can pass freely across the membrane, but the passage of larger molecules, such as amino acids and sugars, is tightly controlled.
text: Only small, nonpolar molecules can pass through the membrane through simple diffusion.
text: Biological cell membranes are selectively permeable, which means that the ease and rate of small molecules passing through membranes vary widely.
text: The molecules binds to the outer surface of the protein and the protein then changes shape allowing the molecule to move across the membrane.
text: Yes, it does restrict many molecules from entering (or leaving) the cell, but it is also designed so that some molecules can very quickly move through the membrane, and thus enter or leave the cell with ease.
text: Electrically neutral and small molecules pass the membrane easier than charged, large ones.
text: Small molecules, such as oxygen, carbon dioxide, and water, are able to pass freely across the membrane, but the passage of larger molecules, such as amino acids and sugars, is carefully regulated.
text: Their hydrophobic regions help to prevent ions or polar molecules inadvertently passing through the membrane.
