Final answer:
Ubiquinone, or coenzyme Q, is the compound that receives electrons from NADH during the electron transport chain in cellular respiration.
Step-by-step explanation:
The compound that receives electrons from NADH during the electron transport chain is ubiquinone, also known as coenzyme Q or simply Q. During this crucial step of cellular respiration, NADH transfers its electrons to Complex I, which then passes them to ubiquinone.
Ubiquinone, being lipid-soluble, freely moves within the inner mitochondrial membrane and after becoming reduced to ubiquinol (QH₂), it carries the electrons to Complex III, continuing the process of energy production.
