1. Enzyme interacts with substrate.
2. Enzyme may undergo a conformational change to capture the substrate ("induced fit" model)
3. Enzyme-substrate complex may undergo several changes to form the product(s).
4. The product(s) are released.
5. The enzyme returns to its original form. It is then ready to do the cycle all over again.
The statements the describe the ecosystems are the following:
1. Balance is required for the survival of an ecosystem.
2. One way to determine an ecosystem's health is by its biodiversity. Biodiversity means having different kinds of plants and animals in an ecosystem.
3. Predators play a role in balancing the earth's ecosystems. These animals are essential in maintaining the food pyramid or the food chain.
Without frequent ground fires to clear out dead brush, a woodland becomes more susceptible to catastrophic wildfires and forest fires that can completely destroy the forest.
However, large forest fires are a natural phenomenon that occur less frequently than small ones.
