<h2>Correct answer is option "A"</h2>

Explanation:

  • The initial concentration of the substrate(Keeping the initial substrate concentration steady permits the specialist to think about the response rates under various natural conditions. The response rates will furnish the scientist with data about the protein's capacity in various situations).
  • A substrate is a substance that is used to make a final product. It is changed and reformed during the process. Sometimes chemical groups are added or taken away.
  • In the cell, enzymes bind and change substrates into their final product. When the enzyme is bound to the substrate, it is known as an enzyme-substrate complex.
  • Substrate concentration is the amount of substrate present that can be turned into a product. The unit of measurement usually assigned to eggs is dozen. Substrate concentration can be measured in various ways. Since the substrates inside the cell are suspended in cellular fluid, the substrate concentration is most commonly measured in molar concentration, or molarity (M), which is moles per liter.
  • Hence,the correct answer is option A "the initial concentration of the substrate.

What is the effect of uneven heat distribution
kondor19780726 [428]

Answer:

Unequal heating of the earth's surface causes temperature differences which cause pressure differences. Lower temperatures  cause higher air pressure. Wind direction is described as where the wind is coming from. For example a northerly wind blows from the north to the south. Usually when we talk about uneven heating of the Earth's surface we are discussing convection. The uneven heating results in some of the atmosphere to be warmer than other parts and changes in volume and pressure which result in updrafts and can cause thunderstorms and other violent weather.
