* ATP (adenosine triphosphate) is the primary energy currency of cells. It's used to power countless cellular processes.

* Organelles are the functional units within cells, each with specific tasks.

Here are some examples:

* Mitochondria: The powerhouse of the cell, mitochondria use ATP to produce more ATP through cellular respiration.

* Ribosomes: Protein synthesis, a crucial process, relies on ATP to move and assemble amino acids.

* Endoplasmic reticulum (ER): ATP is used for protein folding, lipid synthesis, and detoxification within the ER.

* Golgi apparatus: ATP fuels the packaging and sorting of proteins and lipids for transport within the cell.

* Lysosomes: ATP is needed for the breakdown of cellular waste and recycling of materials.

* Vacuoles: ATP is used for maintaining osmotic balance and storing nutrients.

Even though all organelles require ATP, some require it more directly than others. For instance, mitochondria are the primary producers of ATP, so they rely on it for their own processes.
