Q:

In what organelle does cellular respiration occur?

A:

Cellular respiration takes place in the mitochondria. This is where the chemical energy of glucose, carbohydrates, fats and proteins is harvested and partially captured in the form of ATP. Cellular respiration involves glycolysis, the Krebs cycle and oxidative phosphorylation via the electron transport chain. Glycolysis occurs in the cytosol, and the other two processes occur in the mitochondria. In the absence of oxygen, respiration is confined to the cytosol.

Full Answer

An organelle is a component of the cell, such as the mitochondria, that has its own DNA. These entities evolved from independent organisms and eventually became part of the human cell. The mitochondria are referred to as cellular power plants because they generate most of the ATP the cells need for energy. In addition, mitochondria are involved with signaling, differentiation of cells and cellular growth and death.

Mitochondria have also been implicated in diseases such as cardiac dysfunction and autism as well as the aging process. These organelles are composed of particles that perform different functions. While most of human DNA is contained in the nucleus of a cell, mitochondrial DNA resembles the bacterial genome. Most eukaryotic cells, which are found in plants, animals, fungi and other life forms, contain mitochondria.

  • Q:

    Where does respiration occur in the cell?

    A:

    Aerobic respiration on the cellular level occurs in the cell's mitochondria, according Georgia State University. Respiration transforms pyruvate into adensoine triphosphate through the TCA cycle in mitochondria. The TCA cycle, also known as the Krebs cycle, uses enzymes to transport electrons among water, oxygen, carbon and other atoms.

    Where does cellular respiration occur?

    A:

    Cellular respiration occurs in both the cytoplasm and mitochondria of eukaryotic cells. In general, the complete process of cellular respiration is composed of two main parts: glycolysis in the cytoplasm, and the citric acid cycle in the mitochondria.

    What organelle produces ATP?

    A:

    The mitochondria inside a cell produces ATP, or adenosine triphosphate. Cellular respiration is responsible for ATP production, a process in which ATP production occurs after biochemical energy from nutrients is converted.

    How Is Breathing Related to Cellular Respiration?

    A:

    Cellular respiration is directly related to breathing, as breathing provides the necessary oxygen molecules for the process of cellular respiration to take place; cellular respiration is a process by which cells acquire energy. The oxygen provided by breathing is used as a final hydrogen acceptor for the process, explains Antranik.org.
