Which of the following best explains the role of enzymes in a reaction c. an enzyme binds to a product causing a decrease in the rate of the reaction. a. an enzyme causes an increase in the rate of reaction by binding to a substrate. d. an enzyme increases the temperature of a reaction so that the reaction can occur faster. b. an enzyme increases the amount of energy needed to complete the reaction.

The Option A is correct i.e

By increasing the enzyme concentration, the maximum reaction rate greatly increases.

Conclusions:

The rate of a chemical reaction increases as the substrate concentration increases. Enzymes can greatly speed up the rate of a reaction. However, enzymes become saturated when the substrate concentration is high.

answer: tributaries flow into rivers.

wetland is a biome that develops when the water gets accumulated in a land exhibiting a huge depression. these form either seasonally or permanently. the water in the wetland comes from rivers, lakes, ocean, flood, rain or other sources. the wetlands includes mangroves, marshes and peatland.

tributaries flow into the rivers develops a wetland because such water will get deposited in the depression and will restrict the original flow of tributary water. hence, water with low drainage current combines with the river water.

the correct answer is d
