How does the process of cellular respiration work?

Question

Brooklyn Alexander · Accepted Answer

A cell extracts energy from glucose and puts it in a more usable form, as ATP.

Glucose is absorbed by cells from nutrients. It is produced by photosynthesis in plants and moves up the food chain and through the environment. Within respiration, glucose passes through four distinct processes: the Krebs cycle, link reaction, glycolysis, and the electron transport chain. Through these processes, glucose's energy passes through a number of molecules before arriving at ATP. Because it is composed of an adenose sugar head and three phosphates as a tail, ATP is known as adenosine triphosphate. When energy is required, ATP cuts off a phosphate and releases energy into the surrounding environment through the bonds. Though some reactions occur in the cell's cytoplasm, respiration primarily occurs in the mitochondria. The respiratory system's general equation is #C_6H_12O_6 + 6O_2 -> 6CO_2 + 6H_2O + "energy"# Water remains mostly in the body because it can be recycled, but oxygen is inhaled, goes through the bloodstream in humans, and diffuses out of the cell when needed. Carbon dioxide is then produced and exhaled. 34 ATP molecules can ideally be created from the energy in glucose, but this doesn't account for errors in the process because no cell is flawless.

undefined Cellular respiration is a set of metabolic reactions and processes that take place in the cells of organisms to convert biochemical energy from nutrients into adenosine triphosphate (ATP), and then release waste products. It is a key process in both aerobic and anaerobic organisms. In aerobic respiration, oxygen is used as the final electron acceptor in the electron transport chain, while in anaerobic respiration, other electron acceptors are used.
