| Polarization or depolarization of the membrane voltage opens the gate subunits and permits a flood of calcium ions through the cell membrane. |
| The peptides can be linked to a large protein or an oligonucleotide, which may then be carried through the cell membrane. |
| Action potentials are elicited when tiny pores in the nerve cell membrane, known as sodium channels, open up in response to a stimulus. |
| This may be true, but chemically the cyanide will adsorb onto a cell membrane increasing the electron donor or antioxidant capacity of the cell. |
| The insertion of the fusion peptide in the host membrane provides the necessary link between the viral envelope and the cell membrane. |
| The infection of a cell by a virus is a complicated multistage process during which the virus penetrates the host cell membrane. |
