Respiration is the metabolic process by which cells convert nutrients into energy in the form of ATP. It involves a series of biochemical reactions, including glycolysis, the Krebs cycle, and oxidative phosphorylation.
5 Must Know Facts For Your Next Test
Eukaryotic cells primarily perform aerobic respiration, which requires oxygen to produce ATP efficiently.
The mitochondrion is the powerhouse of eukaryotic cells where most stages of cellular respiration occur.
Anaerobic respiration occurs in some microorganisms and does not require oxygen, yielding less ATP compared to aerobic respiration.
Glycolysis is the first step of both aerobic and anaerobic respiration and takes place in the cytoplasm.
In biogeochemical cycles, microbial respiration contributes to carbon cycling by converting organic carbon into carbon dioxide.
