What is the effect of mild heating on tissue metabolism?

• A. Accelerates metabolic tissue rate
• B. Slows metabolic rate
• C. No change in tissue metabolism
• D. Decreases blood flow

Answer: (A)

Mild heating raises tissue temperature, which speeds up biochemical reactions inside cells. Enzymes work more efficiently as temperature increases, so metabolic processes occur faster. This increased enzymatic activity means higher oxygen use and energy demand in the tissue, effectively accelerating the metabolic rate. That’s why the best choice describes metabolism as accelerated. The idea that metabolism slows, doesn’t change, or that blood flow decreases doesn’t fit the typical metabolic response to mild heating—although heating can increase blood flow, the core effect on metabolism is the faster rate.
