Question

b) there are many factors that affect the rate of enzyme - catalyzed reactions, incluc temperature. name another factor.

Explanation:

Enzymes are biological catalysts. The rate of enzyme - catalyzed reactions is affected by several factors. One of the well - known factors is the concentration of the substrate. When there is more substrate available, more enzyme - substrate complexes can form (assuming the enzyme concentration is constant initially), which can increase the reaction rate up to a certain point. Another factor is the concentration of the enzyme. More enzyme molecules mean more active sites available to bind with the substrate, potentially increasing the reaction rate. pH is also a crucial factor. Enzymes have an optimal pH at which they function best. Deviating from this pH can denature the enzyme (change its shape) and reduce the reaction rate. Inhibitors can also affect the rate. Competitive inhibitors compete with the substrate for the active site of the enzyme, while non - competitive inhibitors bind to a different site on the enzyme (allosteric site) and change the enzyme's shape, both of which can reduce the rate of the enzyme - catalyzed reaction.

Answer:

Substrate concentration / Enzyme concentration / pH / Inhibitors.
