C
Water
D
Glucose
Verified step by step guidance1
Understand that cellular respiration is a process that converts glucose into energy in the form of ATP, involving oxidation-reduction reactions.
Identify that oxidation involves the loss of electrons from a molecule, while reduction involves the gain of electrons.
Recognize that in cellular respiration, glucose is the molecule that undergoes oxidation.
During glycolysis and the citric acid cycle, glucose is broken down, and its electrons are transferred to electron carriers like NAD+ and FAD, forming NADH and FADH2.
Conclude that glucose loses electrons during the oxidation phase, which are then used in the electron transport chain to produce ATP.
