Plants and other photosynthetic organisms perform both sets of reactions. Rich P.R. Plants are green because their cells contain an abundance of chlorophyll. Which part of the body will most likely use the cellular respiration? Pyruvate is the pyruvic acid. The body is more likely to inhale because of high carbon dioxide levels in the blood rather than low levels of oxygen. Plant cells do cellular respiration, too. Cellular respiration is a metabolic pathway that allows cells to take apart food molecules and use their atoms as an energy source. They share the initial pathway of glycolysis but aerobic metabolism continues with the Krebs cycle and oxidative phosphorylation. Glucose is broken down to carbon dioxide and water. Science Photo Library - ANDRZEJ WOJCICKI / Getty Images. Pyruvate oxidation and the citric acid cycle. When you chomp food, your body changes the food into a special kind of sugar (like the unique sugar coating on candies) called glucose. In eukaryotes, most cellular respiration reactions take place within the mitochondria. It is often called aerobic respiration because the process requires oxygen (the root aer comes from the Greek word for air). The steps of aerobic cellular respiration are: In glycolysis, glucose in the cytoplasm is broken into two molecules of pyruvate. A portion of the air you breathe never reaches the alveoli. Although energy is also stored in larger molecules, such as complex carbohydrates and fats, they must be broken down into molecules of glucose before the cell can use their energy. The grana and thylakoid are where light-dependent chemical reactions occur (those involving chlorophyll). The respiratory system is a vital organ system that allows for gas exchange.
