Questions: DAY 1, 08:10 SCORE: 40 / 100 PROGRESS: 39% You are now launching an ion! Which three transporters can let ions into a cell? Click on them. Voltage-Gated Aquaporin Antiporter Mechanically-Gated

The three transporters that can let ions into a cell are:

1. Voltage-Gated
2. Antiporter
3. Mechanically-Gated

Explanation for each option:

1. Voltage-Gated: These channels open in response to changes in the electrical membrane potential near the channel. They are crucial for the propagation of electrical signals in neurons and muscle cells, allowing ions to enter the cell.

2. Antiporter: This type of transporter moves ions across the membrane in opposite directions. One ion is transported into the cell while another is transported out. This exchange can help maintain ion balance and is essential for various cellular processes.

3. Mechanically-Gated: These channels open in response to mechanical deformation of the cell membrane, such as stretching or pressure. They allow ions to enter the cell in response to physical changes in the cell's environment.

Aquaporin is not included because it primarily facilitates the transport of water molecules across the cell membrane, not ions.

In summary, the correct transporters that can let ions into a cell are Voltage-Gated, Antiporter, and Mechanically-Gated.
