Q:

What is the end product of glycolysis?

A:

The end product of glycolysis is pyruvate, which can be used in aerobic or anaerobic respiration. Gycolyissis is the process by which glucose is broken down with two molecules of ATP.

Glycolysis is the process that is the first phase of catabolism and is part of cellular respiration. It is needed in order for cells to continue breathing and surviving instead of floundering and becoming obsolete. When there is no oxygen available after gylcolysis has occurred, the pyruvate end product will be used in anaerobic respiration. This type of respiration takes a lot of energy from the cell and requires the cell to use many of its stored sources. When there is a presence of oxygen within the cell, the pyruvate will work using the TCA cycle to perform aerobic respiration. This type of respiration does not require as much energy and results in the cell having a higher amount of usable energy after respiration.

Glycolysis is derived from Greek origins. It literally means the breakdown of something that is sweet. Glucose is a sugar, meaning that it would generally be sweet in a non-cellular environment. The process breaks the sugar down into something that can be used in a practical sense by the cell. The process allows sugars to function within the cell.

  • Q:

    What is the function of pyruvate in cellular respiration?

    A:

    Pyruvate is involved in several steps of cellular respiration including glycolysis, where it is the product of glucose being broken down, the Kreb's cycle uses the pyruvate to complete its process as well. During vigorous exercise, pyruvate is turned into lactate to give more energy to the oxygen-starved muscles.

  • Q:

    What is the process of glycolysis like?

    A:

    Glycolysis is a metabolic process by which a single molecule of glucose is broken down into two pyruvate compounds. Each glucose molecule releases two NADH and ATP molecules during the reaction. Glycolysis is carried out by all living organisms as a mechanism for gaining the necessary energy to sustain life.

    What is anaerobic glycolysis?

    A:

    Anaerobic glycolysis is a metabolic process in which glucose is transformed to lactate. The process occurs when energy is required in the absence of oxygen. Anaerobic glycolysis is essential for tissues with insufficient oxygen supply and high-energy requirements.

  • Q:

    Does glycolysis require oxygen?

    A:

    Glycolysis takes place in the cell's cytoplasm and can occur with or without oxygen. However, without oxygen present, the glycolysis phase of cellular respiration doesn't produce additional adenosine triphosphate, or ATP.
