High km meaning with rate

Web8 de mai. de 2024 · A high Km value means you need a lot of substrate to get the enzyme to act on it. Enzyme feels kinda meh about the substrate in this case. Vmax is simply the rate at which enzyme's do their thing. This is concentration dependent. The more enzymes you have, the higher the Vmax because even more enzyme's are doing their thing. Web17 de fev. de 2024 · At initial reaction time, when t ≈ 0, little product formation occurs, therefore the backward reaction rate of k-2 may be neglected. The new reaction becomes: E + S ↔ ES → E + P Assuming steady state, the following rate equations may be written as: Rate of formation of ES = k 1 [E][S] Rate of breakdown of ES = (k-1 + k 2) [ES]
