Aerobic cellular respiration rates vary according to three main factors: the amount of nutrients available to the cell, the specific type of cell and the ambient temperature. All three factors affect the rate at which respiration takes place, according to UC Clermont College.Know More
Aerobic cellular respiration is the process by which a cell converts nutrients into energy through a chemical reaction, according to UC Clermont College. Without the necessary nutrients, such as oxygen, carbon dioxide, or glucose, a cell cannot perform respiration. This means that a cell lacking nutrients has a lower respiration rate than a cell that has access to all the nutrients it requires, states the Journal of Experimental Botany.
Some types of cells work harder than others; therefore, they require more energy. Productive cells such as neurons, which constantly send information through the nervous system, have higher energy needs than idle cells, such as lipid cells, according to the Journal of Experimental Botany. Therefore, neurons have a higher cellular respiration rate than lipid cells.
The temperature of the environment also affects cellular respiration. The higher the temperature is, the higher the cellular respiration rate is. Heat enhances the cell's ability to convert nutrients into energy by diminishing the amount of work that enzymes have to do. Enzymes are special types of proteins within a cell that do most of the legwork in converting nutrients into energy, according to Mary Freeman of CU Boulder.Learn more about Biology
Cellular respiration products are water, carbon dioxide, heat and adenosine triphosphate or ATP. This applies to aerobic respiration. For anaerobic respiration, cellular respiration products are alcohol or lactic acid, carbon dioxide and ATP.Full Answer >
Many organisms perform cellular respiration, including animals, bacteria, fungi and protozoa, according to CliffsNotes. These organisms use carbohydrates derived from plants to acquire the energy they need to carry out metabolic processes.Full Answer >
The main purpose of cellular respiration is to convert biochemical energy from nutrients into adenoside triphosphate, or ATP, a chemical energy needed by cells to perform certain functions. Muscle and brain nerve cells require energy that contains a high number of mitochondria to perform effectively.Full Answer >
Pyruvate is involved in several steps of cellular respiration including glycolysis, where it is the product of glucose being broken down, the Kreb's cycle uses the pyruvate to complete its process as well. During vigorous exercise, pyruvate is turned into lactate to give more energy to the oxygen-starved muscles.Full Answer >
