Question

How does respiration occur outside of cells?

Answer 1

Hint: All living organisms rely on the chemical reaction known as respiration for their growth, repair, and survival. Respiration takes place in the mitochondria of plants, animals, and humans, which are found in the cytoplasm of the cell. Plants use the energy released during breathing to build amino acids, whereas animals and humans use it to contract their muscles and move.

Complete answer:
A type of respiration is cellular respiration. It must occur in order to provide energy to the cells in a live organism's body. A live organism's cells engage in cellular respiration. It turns nutrients to energy and discards them when they are no longer needed.

Cellular respiration is constantly present. Outside the cells, there is no breathing. Animals and plants both have anaerobic and aerobic respiration. Anaerobic respiration occurs in the cytoplasm of all cells. It is devoid of oxygen from the outside world. Glycolysis is an example.
In mitochondria, aerobic respiration takes place outside of the cytoplasm. Glycolysis produces a substance that enters mitochondria. In terms of ATP, both anaerobic and aerobic respiration provide energy.

The mitochondria of cells do the majority of the effort involved in respiration. In the mitochondria, the energy-rich molecule adenosine triphosphate (ATP) is produced utilising energy from the sun (for plants) or food (for animals and humans). Mitochondria are found in all live cells, albeit some have more than others. Because fat cells store a lot of energy, they have a lot of mitochondria. Muscle cells have a lot of mitochondria because they have to release energy fast when the body needs it.

In plants, respiration occurs in tandem with photosynthesis, another chemical reaction. Plants are autotrophs, which means they produce their own sustenance from carbon dioxide, water, and solar energy. A plant absorbs carbon dioxide from the air and water from its surroundings during photosynthesis through small pores in its leaves, flowers, stems, roots, and branches.

The sun's energy triggers a chemical reaction in the mitochondria, which breaks down carbon dioxide and water molecules and recombines them to form sugar (glucose) and oxygen gas. As a starting point for respiration, glucose is required. To release energy, it consumes glucose produced by photosynthesis and oxygen from the air.

Note:-
Breathing is an important aspect of the metabolic process, however it may not be obvious. Even those without lungs or lunglike structures, most multicellular creatures on Earth use the ample supply of oxygen and carbon dioxide in the atmosphere to help fuel energy production. This is true for plants, insects, and a variety of other living things.
