Question
1. The directional movement of ions by facilitated diffusion through protein channels is determined by O the formation of a secretory vesicle O the electrochemical gradient of the ion being transported the availability of ATP 2. Simple and facilitated diffusion differ because O lons being transported by simple diffusion move along their electrochemical gradients, while ions being transported by facilitated diffusion move against their electrochemical gradients O ions being transported by simple diffusion move against their electrochemical gradients, while ions being transported by facilitated diffusion move along their electrochemical gradients O facilitated diffusion requires the presence of a transport protein within the plasma membrane, while simple diffusion does not O simple diffusion requires the presence of a transport protein within the plasma membrane, while facilitated diffusion does not 3. Changes in the membrane potential trigger the opening or closing of O mechanically-gated channels O voltage-gated channels O ligand-gated channels Prev 1 2 of 10 Score answer > 0Explanation / Answer
1.a) formation of secretory vesicles
.vesicles are formes to transport substances out or into the cell.
2.c)
simple diffusion doesnot require any membrane protein whime facilitaed diffusion require membrane protein.
3.c) voltage gated channel
Voltage-Gated Cation Channels Generate Action Potentials.
