Factors that can affect enzyme activity include:
1. **pH** - Enzymes have an optimal pH range in which they function best. Deviations can lead to decreased activity or denaturation of the enzyme.
2. **Temperature** - Enzyme activity typically increases with temperature up to a certain point (optimal temperature). Beyond this, high temperatures can lead to denaturation.
3. **Substrate Concentration** - Increasing substrate concentration generally increases enzyme activity up to a saturation point, where all active sites of the enzyme are occupied.
4. **Enzyme Concentration** - Increasing enzyme concentration, while substrate is in excess, can increase the rate of reaction.
The **presence of DNA** does not directly influence enzyme activity unless the enzyme in question specifically interacts with DNA (like DNA polymerases or ligases).
The **time of year/season** is not a direct factor that affects enzyme activity, although it could indirectly influence factors like temperature and availability of substrates.
So, the applicable factors from your list are: **pH, temperature, substrate concentration, and enzyme concentration**.
