Which of the following does not occur within mitochondria? Correct Answer Glycolysis
The correct answer is Glycolysis.
- Glycolysis is the Cytoplasm Phase.
- The word glycolysis means "glucose splitting".
- It is the first stage of cellular respiration.
- It is an anaerobic process - it does not need oxygen to proceed.
- There are three Stages of Glycolysis:
- (1) Glucose is trapped and destabilized.
- (2) Two interconvertible three-carbon molecules are generated by cleavage of six-carbon fructose.
- (3) ATP is generated.
- Mitochondria are tubular-shaped organelles that are found in the cytoplasm of every eukaryotic cell.
- They called the powerhouses of the cell because they generate large quantities of energy in the form of adenosine triphosphate (ATP).
- They also have a special role in making cells die (apoptosis).
- Krebs cycle is also known as Citric Acid Cycle or Tricarboxylic Acid Cycle.
- It takes place in the mitochondrial matrix.
- In this process, glucose and other molecules are breaks down into carbon dioxide and water in the presence of oxygen.
- 2 ATP is produced in the Krebs cycle.
- During electron transport, the participating protein complexes push protons from the matrix out to the intermembrane space.
- This creates a concentration gradient of protons that another protein complex, called ATP synthase.
- The Electron Transport chain can be found inside the mitochondrion.
- It removes electrons from electron donors to electron receiver through redox reactions.
- This stage produces most of the energy (34 ATP).
