Expert Solution
Step 1

Malate synthase converts glyoxylate to malate by combining with acetyl CoA. The malate formed can enter citric acid cycle.

The glyoxylate cycle is a cyclic process that converts two carbon fragment acetyl CoA to four-carbon compound succinate.

The glyoxylate cycle occurs in glyoxysomes.
