Adenosine 5'-triphosphate, or ATP, is the most abundant energy carrier molecule in cells. This molecule is made of a nitrogen base (adenine), a ribose sugar, and three phosphate groups.
The energy molecule of a cell is called ATP (Adenosine triphosphate). Cells make this molecule through the process of cellular respiration. Cells use this ATP to transfer molecules and atoms across the cell membrane.
Lysosomes are vesicles that create and transport enzymes to the endoplasmic reticulum. The rough endoplasmic reticulum synthesizes the enzymes. Also, ribosomes synthesize proteins.
