Anna K.S. Photosynthesis and cellular respiration are like two sides of the same coin. In the cell cytoplasm, glucose is broken down to pyruvate. Cellular respiration is the aerobic process by which living cells break down glucose molecules, release energy, and form molecules of ATP. Glucose, a simple sugar, and other carbohydrates made by plants during photosynthesis are broken down by the process of aerobic cellular respiration (requires oxygen) in the mitochondria of the cell. carbohydrates. The energy is then used in the performing of cellular activities. ATP is the energy-carrying molecule produced by the mitochondria through a series of chemical reactions. )�#�j��j:��>d��n� g��r�og��ƽ_Y���O�X����v�9�1G6/W���>��G\�W����q�� The six carbon sugar, glucose, is cut in half and converted into two three-carbon sugars called pyruvate. The process in which glucose is broken down to produce energy is called Glycolysis. During this process, oxygen and glucose are used to produce energy carrying molecules called adenosine triphosphate (ATP). Each reaction is designed to produce some hydrogen ions that can then be used to make energy packets (ATP). This process, called lipolysis, takes place in the cytoplasm. 5. 3 0 obj Mitochondria are the powerhouses of the cell because they “burn” or break the chemical bonds of glucose to release energy to do work in a cell.
