Cellular Respiration and ATP 3135, 3137 Cellular respiration creates energy in the form of ATP for the cell too use for all life functions. There are 2 types of cellular respiration: 1) aerobic and 2) anaerobic. In both cases, the function of respiration is to create energy that is useful to the cells. 1) Aerobic Cellular Respiration: Respiration that uses oxygen is called aerobic respiration. Aerobic respiration creates a lot of useful energy. It creates more energy than anaerobic. It is the most common and familiar to humans. 2) Anaerobic Respiration: Respiration that does not require oxygen is called anaerobic respiration. Anaerobic does not create much energy. It creates less energy than aerobic. Anaerobic bacteria that live in soil and have less access to oxygen do this. REMEMBER THS!!! Aerobic cellular respiration requires oxygen and releases a lot of energy. Anaerobic cellular respiration does not require oxygen and releases small amounts of energy. Aerobic creates more energy than anaerobic. They both produce energy that is useful to the cells. Question 1. Explain the function of cellular respiration. Question 2. What are the two differences between aerobic cellular respiration and anaerobic cellular respiration?
Aerobic Cellular Respiration During aerobic cellular respiration glucose (food) combines with oxygen to create energy, carbon dioxide, and water. The purpose of cellular respiration is to create energy. The energy that is created is useful to the living organism. Cellular respiration takes place in all of the cells of both plants and animals. REMEMBER THIS!!! The equation for aerobic cellular respiration: Glucose + oxygen ENERGY (ATP) + carbon dioxide + water Or C6H12O6 + 6O2 Energy + 6CO2 + 6H2O Interesting Scientific Fact: If you were to reverse the equation for aerobic cellular respiration, it would be the equation for photosynthesis. The waste products of respiration are the starting chemicals for photosynthesis. The waste products for photosynthesis are the starting chemicals for respiration. They are a cycle. ATP The energy that is created during cellular respiration is stored as ATP. ATP is a molecule that stores and releases energy whenever a cell needs it. The energy released from ATP allows the cells to function properly. Most of the energy that is released from ATP is in the form of heat. Interesting Scientific Fact: The heat given off by the release of energy from ATP is what creates your body temperature. That is why when you are exercising, you are warmer than when you are resting. When you are exercising, more cells are using aerobic cellular respiration to make energy. Therefore, when you are exercising, more ATP molecules are being converted into energy which then creates more body heat, but can also be use top help organisms move and provide electrical energy to run the nervous system.
REMEMBER THIS!!! ATP is the energy molecule. It can store and release energy as the cell requires it. Question 3. Without looking, write the equation that describes aerobic cellular respiration. Question 4. What is ATP? How is it used by the cell? How Aerobic Cellular Respiration works: Glucose is a carbohydrate. Remember! Carbohydrates are the energy containing organic molecules. Glucose is created through the digestion of carbohydrates in food. Oxygen is one of the gases in the air. When you breathe, you bring oxygen into your body. The oxygen is then moved to your cells. The glucose from the food you eat, and the oxygen from the air you breathe is both present in every cell. During the process of aerobic cellular respiration they are combined to release energy in the form of ATP, along with the waste products carbon dioxide, and water. Question 5. Explain aerobic cellular respiration and ATP. Interesting Scientific Fact: The mitochondrion is the cell part that performs aerobic cellular respiration. In certain muscle cells that are very active and require a lot of energy, there may be hundreds of mitochondria. (You will need to remember mitochondria and their function for a later unit.) Question 6. What cell structure performs cellular respiration?
Summary Cellular Respiration and ATP 3135, 3137 Cellular respiration is the process of breaking apart glucose molecules to get energy. There are two types of cellular respiration: 1. Aerobic Respiration Using oxygen to break down glucose to release large amounts of ATP energy. 2. Anaerobic Respiration - Breaking down glucose to release smaller amounts of ATP energy with no oxygen present. In both processes, the energy given off is stored in a smaller molecule called ATP. ATP is an abbreviation for a long chemical name. Whenever a cell needs energy, it uses ATP molecules. If a cell runs out of ATP, it cannot carry out its reactions and will die. One difference between aerobic and anaerobic respiration is that many, many more ATP can be created during aerobic respiration than during anaerobic. So whenever a cell is using energy, it is using energy stored in its ATP molecules. Each cell needs to create its ATP, so it must perform cellular respiration. The general equation for aerobic respiration: Glucose and oxygen combine to create ATP(energy) and the waste products carbon dioxide and water. C6H12O6 + 6O2 Energy + 6CO2 + 6H2O
