Verified step by step guidance

Understand the process of oxidative cleavage: Oxidative cleavage involves breaking down a molecule by adding oxygen, which typically results in smaller fragments. In the context of glucose metabolism, this process can lead to the formation of various compounds.

Identify the compounds listed: Starch, sucrose, and cellulose are polysaccharides, which are large molecules composed of glucose units. Acetic acid, on the other hand, is a small molecule with the formula CH₃COOH.

Consider the biosynthetic pathways in plants: Plants can synthesize starch, sucrose, and cellulose from glucose through various enzymatic processes. These pathways involve polymerization of glucose units, not oxidative cleavage.

Analyze the formation of acetic acid: Acetic acid is typically formed through the breakdown of larger molecules, such as fatty acids, rather than directly from glucose through oxidative cleavage. This process involves different metabolic pathways, such as the conversion of pyruvate to acetyl-CoA, which is not directly related to glucose oxidative cleavage.

Conclude which compound cannot be synthesized: Given the nature of oxidative cleavage and the biosynthetic capabilities of plants, acetic acid cannot be synthesized directly from glucose through oxidative cleavage, unlike starch, sucrose, and cellulose.
