What is the process that allows a substance to enter and leave the cell?

Answer 1

The cell has two ways of "eating" substances. The first is active transport. This is when the cell engulfs the food molecule or substance and the food becomes part of the cell. The second way is called diffusion. Substances that are outside the cell, protein for example, are so small that they can move through the cell's membrane without any trouble.

Answer 2

It depends on the substance, but the action could fall into the categories of active transport or diffusion. Some molecules are small enough to diffuse through the membrane through its own kinetic energy alone. This may be facilitated by ion channels as well. The other form is active transport, which could include endocytosis/exocytosis, pinocytosis, or ion pumps.

Answer 3

The process that allows substances to enter and leave the cell is called cellular transport. This process involves movement of molecules across the cell membrane through mechanisms such as diffusion, osmosis, active transport, and facilitated diffusion. These processes help maintain the cell's internal environment and ensure proper functioning.

Answer 4

Active transport facilitated through proteins embedded in the cell's surface, or passive transport facilitated through concentration gradients.

Answer 5

The drug molecules diffuse into the cell.
