Transport Mechanisms in Cells

Fill in the blanks to explain how passive transport maintains homeostasis and life. Molecules are always moving. Without requiring energy, molecules move from areas where they are in _______ concentration to areas where they are in _______ concentration. This is called _______ transport. When this occurs with water molecules it is called _______. When molecules balance out but are still moving this is called _______. When molecules move against the concentration gradient, they move from areas of _______ concentration to areas of _______ concentration. This is called _______ transport and _______ is required to make this occur.

Identify each of the following types of transport, and explain how you can tell

In the body, red blood cells are in a 0.9% salt solution. What would happen to these cells if they were placed in a 10% salt solution? (Hint: draw a picture to help you figure it out)

Difference between hypertonic, isotonic, or hypotonic.

In your own words, describe what cellular respiration is, and why it is important.

What process is represented by this equation? 6 CO₂ + 6 H₂O + Light → C₆H₁₂O₆ + 6 O₂
