Question

what are the products of the krebs cycle? (sometimes the formatting for these answers makes part of it bold; ignore any strange formatting. just choose the correct answer regardless of what is in bold.) multiple choice
atp nad+ fadh₂
co₂ atp fadh₂
atp and nadh
co₂ and atp

Explanation:

The Krebs cycle (citric acid cycle) produces carbon dioxide ($\ce{CO_2}$), ATP (adenosine triphosphate), and $\ce{FADH_2}$ (flavin adenine dinucleotide, reduced form), along with $\ce{NADH}$. Among the options, the one with $\ce{CO_2}$, ATP, and $\ce{FADH_2}$ is correct. The first option has $\ce{NAD+}$ (oxidized form, not a product here), others are incorrect. So the correct option is the one with $\ce{CO_2}$, ATP, $\ce{FADH_2}$.

Answer:

B. $\ce{CO_2}$, ATP, $\ce{FADH_2}$ (assuming the second option is labeled B, with the content $\ce{CO_2}$, ATP, $\ce{FADH_2}$)
