Respiration releases energy from nutrients from "summary" of The Biology Book by DK
Respiration is a vital process that occurs within cells, allowing organisms to obtain the energy they need to carry out various functions. Through respiration, energy is released from the nutrients that organisms consume, such as glucose. This energy is then used to power the various processes that keep the organism alive and functioning. The process of respiration can be broken down into two main types: aerobic respiration and anaerobic respiration. Aerobic respiration requires oxygen to take place and is the most efficient way for cells to produce energy. During aerobic respiration, glucose is broken down in the presence of oxygen to produce carbon dioxide, water, and a large amount of ATP, the molecule that stores and releases energy for the cell to use. On the other hand, anaerobic respiration occurs in the absence of oxygen and is a less efficient way for cells to produce energy. Anaerobic respiration also involves the breakdown of glucose, but it produces lactic acid or ethanol as byproducts, along with a smaller amount of ATP compared to aerobic respiration.- Respiration is a crucial process for organisms to obtain the energy they need to survive. By breaking down nutrients through respiration, organisms can generate the ATP required to power their cells and carry out essential functions. Whether through aerobic or anaerobic respiration, the end goal remains the same: to release energy from nutrients and use it to sustain life.
