Correct answer: regulate the uptake and removal of materials.
Active and passive transport are important processes that help the cell regulate the uptake and removal of materials.
To determine which statement is correct, we can look at the definitions and functions of active and passive transport.
Active transport refers to the movement of molecules or ions across a cell membrane against their concentration gradient, meaning from an area of lower concentration to an area of higher concentration. This process requires the cell to expend energy in the form of ATP (adenosine triphosphate). Active transport is important for maintaining the cellular membrane's integrity and regulating the uptake and removal of materials, as it allows the cell to control the movement of specific substances in and out of the cell.
Passive transport, on the other hand, does not require the use of energy. It is the movement of molecules or ions across a cell membrane along their concentration gradient, meaning from an area of higher concentration to an area of lower concentration. Passive transport can occur through different mechanisms such as diffusion, osmosis, and facilitated diffusion. While passive transport is essential for metabolizing materials and maintaining the cellular membrane, it does not actively regulate the uptake and removal of materials like active transport does.
Considering these explanations, we can conclude that the correct statement is: Active and passive transport are important processes that help regulate the uptake and removal of materials.
