Question
Cellular respiration occurs in which of the following part of cell?
- Chloroplast
- Mitochondria
- Cytoplasm
- Both b and c are involved
Hint:
Adenosine triphosphate (ATP) is produced via a series of metabolic events and processes known as "cellular respiration," which occur in almost all the living cells.
Depending upon the use of molecular oxygen in oxidation, respiration can be classified into types-
aerobic respiration (uses molecular oxygen in oxidation), anaerobic respiration (occurs in absence of oxygen) and fermentation.
The correct answer is: Both b and c are involved
Mitochondria and cytoplasm are the sites involved in cellular respiration.
- Prokaryotic cells carry out the process in the cytoplasm, while eukaryotic cells start the process in the cytosol (cytoplasm) and finish it in the double membrane-bound organelle called- mitochondria.
- Glycolysis, Krebs' cycle (also known as the citric acid cycle), and oxidative phosphorylation via the electron transport chain are the steps of cellular respiration in eukaryotes.
