What is the process of using oxygen to release energy from food called?
Respiration
The source of the energy required to regenerate ATP is the chemical energy stored in food (e.g. glucose). The cellular process of releasing energy from food through a series of enzyme-controlled reactions is called respiration .
In which process is oxygen used to release the energy stored?
cellular respiration
Aerobic cellular respiration is the process by which cells use oxygen to help them convert glucose into energy.
What is a process that requires energy to produce food?
Most autotrophs use a process called photosynthesis to make their food. In photosynthesis, autotrophs use energy from the sun to convert water from the soil and carbon dioxide from the air into a nutrient called glucose.
What process releases energy?
respiration
The energy is released during respiration. During cellular respiration, glucose is broken down in the presence of oxygen to produce carbon dioxide and water. The energy released during the reaction is captured by the energy-carrying molecule ATP (adenosine triphosphate).
What is the breakdown of food using oxygen?
Respiration using oxygen to break down food molecules is called aerobic respiration . ‘Aero’ means air, which contains oxygen, leading to the name aerobic respiration. Glucose is the molecule normally used for respiration – it is the main respiratory substrate .
What type of metabolism occurs in the absence of oxygen?
Anaerobic metabolism
Anaerobic metabolism, which can be defined as ATP production without oxygen (or in the absence of oxygen), occurs by direct phosphate transfer from phosphorylated intermediates, such as glycolytic intermediates or creatine phosphate (CrP), to ADP forming ATP.
What energy does respiration release?
ATP
Respiration releases energy – it is an exothermic process. The energy is stored in molecules of ATP . ATP can be broken down in other processes in cells to release the stored energy. Don’t confuse respiration with photosynthesis.
