Solution

The correct option is D

Glycolysis


The correct option is D:
Explanation for Correct option:

  1. Glycolysis is the first step of cell breath happening in quite a while, and plants are vigorous and anaerobic organic entities.
  2. During glycolysis, glucose is to some extent oxidized to two atoms of pyruvic corrosive.

Explanation for the incorrect options:

Option A;

  1. The carboxyl corrosive (TCA) cycle, otherwise called the Krebs or citrus extract cycle, is the fundamental wellspring of energy for cells and a significant component of oxygen-consuming breath.
  2. The cycle outfits the accessible synthetic energy of acetyl coenzyme A (acetyl CoA) into the lessening force of nicotinamide adenine dinucleotide (NADH).

Option B:

  1. Aging is a substance process by which atoms, for example, glucose, are separated anaerobically.
  2. All the more comprehensively, maturation is the frothing that happens during the production of wine and brew, a cycle no less than 10,000 years old.

Option C:

  1. The inner mitochondrial membrane contains the ETS, or electron transport system.
  2. In the process of cellular respiration, glucose-derived electrons proceed steadily down the electron transport chain in the direction of oxygen, passing through states with progressively lower energies and releasing energy at each stage.
  3. To store this energy as ATP is the aim of cellular respiration.

Final Answer: The first phase in the breakdown of glucose, in animal cell, is glycolysis.
