Q. Sequence of events in Kreb’s cycle is
A) Acetyl Co-A $\rightarrow$ Citrate $\rightarrow$ Pyruvate $\rightarrow$ Oxaloacetic acid $\leftarrow$ fumarate $\leftarrow$ Malate $\leftarrow$ Succinate $\mathbf{\alpha}$-ketoglutaralte
B) Acetyl Co-A $\rightarrow$ Citric acid $\rightarrow$ $\mathbf{\alpha}$-ketoglutarate acid $\rightarrow$ Oxaloacetic acid $\leftarrow$ Malic acid $\leftarrow$ Fumaric acid $\leftarrow$ Succinic acid
C) Acetyl Co-A $\rightarrow$ Citric acid $\rightarrow$ Malic acid Oxaloacetic $\leftarrow$ Oxaloacetic acid Succinic $\leftarrow$ $\mathbf{\alpha}$-ketoglutaric acid $\leftarrow$
D) All are wrong
Explanation
The correct answer is Option B: Acetyl Co-A $\rightarrow$ Citric acid $\rightarrow$ $\mathbf{\alpha}$-ketoglutarate acid $\rightarrow$ Oxaloacetic acid $\leftarrow$ Malic acid $\leftarrow$ Fumaric acid $\leftarrow$ Succinic acid.
