Which statement about the enzymes ALS and EPSP is false?

The statement that is false is the one indicating that ALS and EPSP are found in both plants and animals. ALS (Acetolactate synthase) and EPSP (5-enolpyruvylshikimate-3-phosphate) are enzymes that play crucial roles in various metabolic pathways essential for plant growth and development. Specifically, they are involved in the biosynthesis of amino acids and secondary metabolites in plants.

Both of these enzymes are specific to the shikimic acid pathway, which is present in plants, certain microorganisms, and fungi but is not found in animals. This pathway is vital for synthesizing aromatic amino acids, which are important for protein synthesis in plants. Since animals do not possess this pathway or these enzymes, it's accurate to say that ALS and EPSP are not present in animal metabolism.

In contrast, the other statements are true: these enzymes are indeed essential for plant growth and operate in distinct metabolic pathways integral to the plant lifecycle.
