vredina [299]

Answer: Aerobic respiration will not take place and the animal will lose large amounts of ATP.

Explanation:

Mitochondria is the powerhouse that converts product of glycolysis that occurs in the cytoplasm into energy and release carbon dioxide as a byproduct. In the presence of oxygen (aerobic), products of glycolysis such as pyruvate enters the mitochondria, joins the kreb cycle and the electron transport chain yielding a large amount of energy or ATP.

Aerobic respiration that yield large amounts of ATP strictly occus in the mitochondrial matrix whereas anearobic respiration occurs in the cytoplasm.

<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.
