The path from a missing vitamin to a clinical symptom follows a fixed sequence. A vitamin is converted into its active coenzyme form. That coenzyme binds to a specific enzyme and enables a specific reaction. When the coenzyme is absent, that enzyme step slows or stops. The metabolic pathway that depends on that step becomes impaired. Tissues that rely heavily on that pathway are the first to malfunction. The symptom we observe is the functional consequence of that tissue's failure. Because each coenzyme serves only certain enzymes, the block is specific, not global. This is why one missing vitamin produces a characteristic symptom set rather than a random collection of problems.

2 / 3
Follow the chain from left to right. The vitamin becomes a coenzyme. That coenzyme enables one specific enzyme step. When the vitamin is missing, that step is blocked. The pathway that depends on it slows. The tissue that relies on that pathway malfunctions. The symptom is the visible result of that tissue failure. The block is specific because each coenzyme fits only certain enzymes, so only certain pathways are affected.
