![]() It is often called aerobic respiration because the process requires oxygen (the root aer. Cellular respiration takes place in the cells of animals, plants, and fungi, and also in algae and other protists. ![]() These molecules enter the matrix of a mitochondrion, where they start the Krebs cycle. These include glycolysis, the preparatory reaction, the citric acid cycle, and th. vector diagram presentation of the processes of aerobic cellular respiration. Recall that glycolysis, stage I of cellular respiration, produces two molecules of pyruvate. This 2-minute animation discusses the four stages of cellular respiration. Simple Designing of Cellular Respiration Equation. movement - in animals, energy is needed to make muscles contract, while in plants, it is needed for transport of substances in the phloem close phloem The tissue in plants that transports the products of photosynthesis, including sugars and amino acids. Cellular respiration is the process by which organisms use oxygen to break down food molecules to get chemical energy for cell functions. Cellular Respiration Stage II: The Krebs Cycle.in plants, and the products of digestion close digestion The breakdown of large insoluble food molecules to smaller soluble ones. Algae subsumed within plants and some bacteria are also photosynthetic. Oxygen is produced as a by-product of photosynthesis. from the products of photosynthesis close photosynthesis A chemical process used by plants to make glucose and oxygen from carbon dioxide and water, using light energy. and lipids close lipid Fat or oils, composed of fatty acids and glycerol. This respiration also occurs in the absence of oxygen. In lactic acid fermentation, one molecule of glucose is degraded into lactic acid and energy. One of the three main food groups, proteins are needed by the body for cell growth and repair. The overall equation of anaerobic respiration is: C6H12O6 + 2ADP + 2Pi 2C2H5OH + 2CO2 + 2ATP. ![]() In plants, carbohydrates are important for photosynthesis., proteins close protein Organic compound made up of amino acid molecules. Carbohydrates are vital for energy in humans and are stored as fat if eaten in excess. The first half is known as the energy requiring steps. There are two halves of glycolysis, with five steps in each half. This pathway breaks down 1 glucose molecule and produces 2 pyruvate molecules. This pathway is anaerobic and takes place in the cytoplasm of the cell. to drive the chemical reactions needed to keep organisms alive - the reactions to build complex carbohydrates close carbohydrate Food belonging to the food group consisting of sugars, starch and cellulose. Glycolysis is the first pathway in cellular respiration.
