How does substrate concentration affect reaction rates?

How does substrate concentration affect reaction rates?

Substrate concentration can significantly impact reaction rates. Generally, as substrate concentration increases, the rate of reaction also increases until it reaches a maximum rate.

What happens when the substrate concentration is too high?

When substrate concentration is too high, the reaction may reach a saturation point where all active sites of the enzyme are occupied, and the rate of reaction levels off.

Can you explain the concept of saturation in more detail?

Sure! Saturation occurs when all enzyme active sites are filled with substrate, meaning adding more substrate won't increase the reaction rate.

Are there any factors other than substrate concentration that affect reaction rates?

Yes, other factors include temperature, pH, enzyme concentration, and the presence of inhibitors or activators.
