Enzymes can catalyze a reaction only if they
encounter a substrate that fits their active site.
Which step of cellular respiration occurs outside the mitochondria?
glycolysis
The three stages of cellular respiration (in order) are
glycolysis, the Krebs cycle, and oxidative phosphorylation.
Glycolysis is an anaerobic process, indicating that the glycolytic reactions
require no oxygen.
Photosynthesis and cellular respiration are both complementary and balanced, but the early history of life on Earth showed increasing oxygen concentrations. This indicates that
the amount of photosynthesis exceeded the amount of cellular respiration.
