What might happen if catalysts are not adequately supplied in muscle cells?

When catalysts, such as enzymes, are not adequately supplied in muscle cells, the biochemical reactions that depend on these catalysts can be severely impaired. Enzymes serve as catalysts that accelerate the rate of metabolic processes, including those involved in energy production and muscle contraction.

Without sufficient enzymes, the metabolic pathways that generate ATP—the primary energy currency for muscle function—would be significantly disrupted. This can lead to an inability to produce the necessary energy for muscle contractions, ultimately resulting in dysfunction. Thus, muscle fibers may not be able to perform their normal roles, leading to compromised muscle activity and performance.

In this context, the other options are less feasible. Normal function of muscle fibers would not be maintained without proper enzymatic activity. Lacking energy is a symptom rather than a complete description of the outcome, as the muscle fibers may completely fail to function at all without catalysts. Overproduction of ATP is also not a likely scenario; instead, a lack of catalysts usually results in insufficient ATP production. Therefore, the most accurate conclusion is that muscle fibers would be unable to function effectively in the absence of adequate catalysts.
