How many oxidation steps are involved in aerobic respiration during acetylation and Krebs cycle?
1 Two
2 Four
3 Three
4 Five
Explanation:
Exp:B There are four oxidation steps are involved in aerobic respiration during acetylation and Krebs cycle. (A) Isocitrate to alpha-Ketoglutarate (B) Alpha-ketoglutarate to succinyl Co-A (C) Succinate to Fumarate (D) Malate to oxaloacetate

Which statement is wrong for Krebs' cycle?
1 There are three points in the cycle where $\mathrm{NAD}+$ is reduced to $\mathrm{NADH}+\mathrm{H}+$
2 There is one point in the cycle where FAD+ is reduced to FADH
3 During conversion of succinyl CO-A to succinic acid, a molecule of GTP is synthesised
4 The cycle starts with condensation of acetyl group (acetyl CO-A) with pyruvic acid to yield citric acid
Explanation:
Exp:D The kreb's cycle starts with condensation of acetyl CoA with oxaloacetic acid and water to provide citric acid. Each turn of the cycle forms three NADH molecules and one $\mathrm{FADH}_{2}$ molecule. One GTP molecule is synthesised during conversion of succinyl CoA to succinic acid. Fig :- Kreb's cycle

Biological oxidation in Krebs cycle involves:
1 $\mathrm{O}_{2}$
2 $\mathrm{N}_{2}$
3 $\mathrm{CO}_{2}$
4 $\mathrm{SO}_{2}$
Explanation:
Exp:A There is no need of oxygen in Krebs cycle directly but it can only take place when oxygen is present because it depends on by products from the electron transport chain which needs oxygen.

Which of these is not a ketone body?
1 Acetoacetic acid
2 Acetone
3 Succinic acid
4 Betahydroxy butyric acid
Explanation:
Exp:C Ketone bodies are produced by the liver and used peripherally as an energy source when glucose is not readily available. Hence, succinic acid is not a ketone body
