Cellular respiration
Storyboard Text
- Cellular Respiration
- That's interesting!
- Hello guys! Let's talk about cellular respiration.
- Cellular Respiration
- And guys, do you know what is ATP?
- Cellular respiration can be defined simply as a series of metabolic processes that take place within a cell.
- Mitochondria are also responsible for generating clusters of iron and sulfur, which are important cofactors of many enzymes
- Cellular Respiration
- ATP is produced directly in the reactions that transform glucose. Much more ATP, however, is produced later in a process called oxidative phosphorylation.
- During cellular respiration, a glucose molecule is gradually broken down into carbon dioxide and water.
- 1
- The oxidation of these molecules is primarily used to transform the energy contained in these molecules into ATP.
- Cellular Respiration
- The Krebs cycle is the second of three stages of cellular respiration, in which glucose, fatty acids and certain amino acids, the so-called fuel molecules, are oxidized
- 2
- The stages of cellular respiration include glycolysis, pyruvate oxidation, the citric acid or Krebs cycle, and oxidative phosphorylation.
- Cellular Respiration
- During cellular respiration, a glucose molecule is gradually broken down into carbon dioxide and water.
- Plants have mitochondria and can perform cellular respiration.

- Cellular Respiration: C6H12O6 + 6O2 → 6CO2 + 6H2O
- This is the chemical equation for cellular respiration.

- Electron transport is the stage that produces the most ATP molecules. The electron transport chain is a collection of carrier proteins found on the inner membrane of mitochondria. NADH release the hydrogen ions and electrons into the transport chain.
