Answer:
Water, fresher climate, not only scientific factors but also a psychological factor (nice beaches, palms, other wildlife, etc.)
First of all, it makes algae grow, because pesticides and stuff provide too many nutrients. Algae needs a lot of oxygen and so the fish begin to die off because the algae is taking all the oxygen out of the lake. Next, it causes biodiversity to drop, meaning that species are beginning to get less varied. Water pollution harms the lakes and is a concern because the effects of it on species and the water will stay.
Answer:
a. It is a competitive inhibitor.
Explanation:
A competitive inhibitor competes with the substrate for the active site of the enzyme. Binding of the competitive inhibitor to the active site of enzyme forms enzyme-inhibitor complex and does not allow the substrate to bind to the enzyme. This inhibits the reaction. However, the competitive inhibition is overcome by increasing the concentration of substrate around the enzyme to facilitate its binding to the enzyme's active site.
According to the given information, malonic acid competes with succinate for the active site of enzyme succinate dehydrogenase and inhibits the reaction. This inhibition is overcome by increasing the succinate concentration around the enzyme. This makes malonic acid a competitive inhibitor to succinate dehydrogenase.
