DNA RNA -Helps with protein synthesis by mRNA (messenger RNA), tRNA (transfer RNA), and rRNA (ribosomal RNA). -Stores genetic information. -Maintains growth and repair. -Controls all cellular activities. -Contains protein codes. -Ensures each daughter cell & gamete receives exact genetic information. Functions/roles Cytoplasm, nucleus Nucleus & mitochondria Location in cell
ATP: Relating the structure to its role as the “energy currency” of cells
ATP is like a “ coin/currency ” and when it is required, ATP can be used to provide a readily available source of energy for synthesis of molecules, nerve impulses, muscle contraction, chemical reactions, transport of molecules etc.
