B
Release of CO2 and release of coenzyme A
C

검증된 단계별 안내1
Understand the context: Pyruvate conversion to acetyl CoA is a crucial step in cellular respiration, linking glycolysis to the citric acid cycle.
Identify the key components involved: Pyruvate, acetyl CoA, CO2, NAD+, and NADH are involved in this conversion process.
Recognize the chemical reaction: Pyruvate undergoes oxidative decarboxylation, where it loses a carbon atom in the form of CO2.
Consider the role of NAD+: During this conversion, NAD+ is reduced to NADH, capturing high-energy electrons.
Conclude the process: The conversion results in the release of CO2 and the formation of acetyl CoA, with NADH being synthesized, not ATP.
