The gas exchange process is performed by the lungs and respiratory system. Air, a mix of oxygen and other gases, is inhaled. In the throat, the trachea, or windpipe, filters the air.

Answer:
The two cycles are photosynthesis and cellular respiration.
Cellular respiration releases energy stored in glucose (during photosynthesis). Most of this energy is transferred to an energy molecule that can be used by all cells: ATP.
And the wastes of respiration are carbon dioxide and water, which are precisely the raw materials of photosynthesis in chloroplasts (forming two linked closed cycles).
Explanation:
Answer:
In lactic acid fermentation, pyruvate from glycolysis changes to lactic acid. This type of fermentation is carried out by the bacteria in yogurt, and by your own muscle cells. In alcoholic fermentation, pyruvate changes to alcohol and carbon dioxide. This type of fermentation is carried out by yeasts and some bacteria.
