Multiple Choice

In aerobic cellular respiration, pyruvate molecules must be transformed through a process called pyruvate oxidation before they can be broken down in the Krebs Cycle. What are the products of pyruvate oxidation?

Acetyl CoA, O₂, and ATP.

Acetyl and CO₂.

Acetyl CoA, FADH₂, and CO₂.

Acetyl CoA, NADH, and CO₂.

Acetyl CoA, NAD⁺, ATP, and CO₂.

Verified step by step guidance

Understand the context: Pyruvate oxidation is a crucial step in aerobic cellular respiration, occurring in the mitochondria after glycolysis and before the Krebs Cycle.

Identify the main reactant: Pyruvate, which is produced from glucose during glycolysis, is the starting molecule for pyruvate oxidation.

Recognize the transformation: Pyruvate is converted into Acetyl CoA, which is necessary for entering the Krebs Cycle.

Identify the by-products: During pyruvate oxidation, NAD+ is reduced to NADH, and CO2 is released as a waste product.

Summarize the products: The complete products of pyruvate oxidation are Acetyl CoA, NADH, and CO2, which are essential for further energy production in the Krebs Cycle.
