Question

Exercise Question 32 INCORRECT. Fatty acids with an odd number of carbon atoms also generate acetyl-CoA which can be used in the glyoxylate cycle. The glyoxylate cycle in germinating seeds is a pathway that has some similarity to the citric acid cycle, but it uses the carbon- based products from the catabolism of fatty acids as the precursors for gluconeogensis. How can the glyoxylate cycle accomplish this? Its reactions bypass the decarboxylation steps of the citric acid cycle. It prevents the formation of malate, which can form oxaloacetate. oIt produces an excess of ctrate, whch s sported out of the mtochondria. Its reactions take place partly in the matrix of the mitochondria and partly in the cytosol. It uses only the catabolic products of saturated fatty acids with an even number of carbon atoms

Explanation / Answer

Glyoxylate cycle is an anabolic pathway operating in plants, bacteria, fungi but is absent in animals. it centers around conversion of acetyl coA to succinate for synthesis of carbohydrates. It differs from TCA cycle in that the decarboxylation reactions dont operate here.

So option A is correct
