Petrified fossils (permineralization) form when dissolved minerals infiltrate the porous tissues of dead organisms and harden, turning the remains into stone while preserving internal structure. Mold and cast fossils are impressions, trace fossils are tracks or burrows. Petrified wood is a common example.

Explanation:
Adenosine triphosphate (ATP) is the universal energy currency of the cell, storing energy in its high-energy phosphate bonds. Hydrolysis to ADP releases energy for cellular work. NADH and FADH₂ are electron carriers in respiration, ultimately used to produce ATP. Glucose is a fuel molecule, broken down to produce ATP. ATP is directly used in processes like muscle contraction and active transport.
