Verified step by step guidance

Identify the role of each molecule listed in the options: ATP, NADH, FADH2, and Glucose.

Understand that ATP (Adenosine Triphosphate) is the primary energy currency of the cell, providing energy for most cellular processes.

Recognize that NADH and FADH2 are electron carriers involved in cellular respiration, specifically in the electron transport chain, where they help generate ATP.

Note that Glucose is a primary energy source that is metabolized through glycolysis and cellular respiration to produce ATP.

Conclude that ATP is the molecule that directly supplies energy for most chemical reactions in cells, as it releases energy when its phosphate bonds are broken.
