Inside the body they preform cellular respiration‚ they take in nutrients from the cell‚ break it down‚ and turn it into energy. This energy is then used by the cell to carry out various life processes. Without this energy‚ none of the organelles within the cell would be able to function

questions: Cellular respiration: • What is cellular respiration and what are its three stages? Cellular respiration is the process by which cells harvest energy that is stored in food. The three stages are glycolysis‚ citric acid cycle‚ and electron transport. • What is the role of glycolysis? Include the reactants and the products. Where does it occur? Glycolysis which mean splitting sugar‚ with oxygen it is the first step in cell respiration‚ without oxygen

and energy as follows: C5 H12 O6 2C3 H6 O3 + energy Anaerobic respiration is a stage of cellular respiration that happens in the absence of oxygen. The first step is the breakdown of glucose in glycolysis. During this step glucose is broken down to two pyruvic acid molecules. The fate of pyruvic acid depends on whether there is oxygen available or not. In the absence of oxygen‚ pyruvic acid continues the anaerobic respiration pathway and is converted into lactic acid. Only six ATP molecules

study the effects of ethanol on the cellular respiration of mealworms. Cellular respiration is the process by which cells harvest the energy stored in food. It is the intake of oxygen and energy in the form of glucose‚ and the cells ability to break it down into carbon dioxide‚ water‚ and energy required for the body to function. More scientifically‚ it is a three-step pathway that produces ATP (adenosine triphosphate.) The three stages of cellular respiration are: glycolysis‚ the citric acid cycle

fermentation which occur under anaerobic respiration to produce ATP without the use of oxygen. Anaerobic respiration takes place in certain prokaryotic organisms that have an Electron Transport Chain (ETC) but do not use oxygen as a final electron acceptor at the end of the chain (Campbell et all‚ 2015) different with the aerobic respiration which use oxygen to produce ATP and its final electron acceptor will be oxygen. The net product of energy for anaerobic respiration is 2 ATP molecules per glucose molecule

plants transform radiant solar energy into chemical energy that gets stored as potential energy in carbohydrates‚ and conduction of nerve impulses which is when chemical energy is transformed into electrical energy. An example of energy transfer is; respiration when the chemical energy stored in respiratory substrates is transferred to ADP and is stored in ATP. The ATP molecules transfer energy to other biological molecules. ATP‚ which stands for adenosine tri-phosphate‚ is an energy rich compound having

animals eat the plants‚ and take the carbon in the sugars‚ inside their cells they take the energy from the food‚ this is cellular respiration‚ which takes oxygen (product of photosynthesis) and makes carbon dioxide (also used in photosynthesis) ‚ it then gives energy by breaking down the food molecules‚ this is the link between the two. There are two types of cellular respiration; aerobic and anaerobic. Both use the same steps‚ where the sugar created during photosynthesis is broken down. (Audesirk
