Explain the 3 stages of cellular respiration
Glycolysis:
How many ATP are produced? ____
Other notes about this stage:
Glycolysis is the first stage of cellular respiration and occurs in the cytoplasm of the cell. It is a process that breaks down one molecule of glucose into two molecules of pyruvate. During glycolysis, a small amount of ATP is produced directly, with a net gain of 2 ATP molecules. Additionally, two molecules of NADH are also produced, which will further contribute to the production of ATP in the later stages of cellular respiration.
Other notes about this stage include:
- Glycolysis does not require oxygen and is therefore considered anaerobic.
- It is the same in both aerobic and anaerobic respiration.
- The process involves a series of chemical reactions, facilitated by enzymes, that convert glucose into pyruvate, releasing energy in the form of ATP and NADH.
- Each molecule of glucose undergoes 10 reactions in glycolysis.
- Glycolysis is the most ancient pathway for energy production and is present in all living organisms.
