Question

Complete oxidation of acetyl from acetyl-CoA during TCA cycle forms:

• A. ${\mathrm{CO}}_2$
• B. ${\mathrm{NADH}}_2$
• C. Alcohol
• D. ${\mathrm{FADH}}_2$

Answer 1

Answer: (A), (B), (D)

${\mathrm{FADH}}_2$

TCA cycle or Kreb's cycle takes place in the mitochondria. Pyruvic acid produced during glycolysis is converted to acetyl-CoA and enters this cycle. Acetyl part of acetyl-CoA is completely oxidised during TCA cycle and $H_{2}O,{\mathrm{NADH}}_2,{\mathrm{FADH}}_2$, ${\mathrm{CO}}_2$ are formed.
