Which outcome limits an enzyme's catalytic rate inside cells?

💡 Explanation

The reaction reaches maximal velocity (Vmax) when substrate arrival becomes rate-limiting, known as diffusion limitation, because the enzyme active site is unoccupied a significant amount of time; therefore substrate diffusion restricts catalysis, rather than conformational instability playing the dominant role.
