Question

Cells can make certain molecules when needed for a certain function. What happens when those molecules are no longer needed? They return to the cell nucleus. They float freely in the cell. They are broken down. They are stored for later use.

Answer 1

Molecules that are no longer needed by the cell are typically broken down in a process that is part of the cell's catabolic metabolism. This breakdown helps maintain cellular homeostasis by recycling components and releasing stored energy.

Step-by-step explanation:

When cells make certain molecules that are needed for specific functions, what happens when those molecules are no longer needed? The answer is that these molecules are typically broken down. This process of breaking down complex molecules is part of the cell's catabolism, which is one half of the cellular metabolism. The process is essential for maintaining cellular homeostasis as it helps in recycling components and preventing the accumulation of unnecessary or potentially harmful molecules.

Once the molecules are broken down, the energy that was stored in their chemical bonds may be released and used for various cellular processes, such as cellular respiration. Additionally, the breakdown products can be further processed or excreted as waste, depending on the nature of the molecule and the needs of the cell and organism

Answer 2

It would be the last choice. They are stored for later use.
