Answer:
C. Succinate is the substrate, and fumarate is the product.
Explanation:
Succinate is the substrate of the enzyme Succinate dehydrogenase, and as a product is obtained fumarate. In this scenario, malonic acid plays the role of a competitive inhibitor because its structure resembles the succinate's, so they compete for the active site of the enzyme. So, A option is wrong because fumarate is not the product. B option is wrong too because malonic acid is an inhibitor, not the substrate. Also, D is incorrect because malonic acid is a COMPETITIVE inhibitor, not a noncompetitive one. Finally, E can´t be true because malonic acid is not product and fumarate is the product, not an inhibitor.

Answer:
The coastal upwelling and changes in wind and water circulation patterns is the main natural cause of dead zones.
Fertilizers cause hypoxia due to the over growth of algae on the surface of water bodies.
Explanation:
Coastal upwelling is the cause of dead zones in which water that is present in depth comes to the surface of ocean due to the movement of water because of wind. Fertilizers cause hypoxia due to the over growth of algae on the surface of water bodies. The fertilizers increases the algal growth by providing nutrients necessary for its growth. This over growth decreases oxygen concentration in water and affect marine organisms.
Answer:
Both photosynthesis and cellular respiration occur in plants. However, the rate of photosynthesis exceeds that of cellular respiration during the day when there is sunlight. The Chlorophyll pigment picks up energy from the photons and uses it to reduce carbon dioxide into carbohydrates. During the night, when there is little sunlight, the rate of photosynthesis drops down below that of cellular respiration, that breaks down these energy molecules made in photosynthesis to supply the plant’s cellular processes with energy.
