Question
How do substances like CO2 and water move in and out of the cell? Discuss.
Solution
Substances like CO2 (carbon dioxide) and water move in and out of the cell through a process known as diffusion. Here are the steps:
-
Concentration Gradient: The first step in this process is the creation of a concentration gradient. This means that the substance is more concentrated in one area than another. For example, a cell might have a lot of CO2 because it's a waste product of cellular respiration, but there's less CO2 outside the cell.
-
Movement of Substances: Once a concentration gradient is established, substances will naturally want to spread out evenly. This is similar
