Avery's experiments showed that bacteria are transformed by “transforming principle” – DNA.
When Griffit in his experiments showed that R-strain bacteria (non-virulent) could be transformed by the heat-killed S bacteria, and become virulent, scientists assumed that there is some kind of “transforming principle” that is involved.
Avery and his colleagues cultured heat-killed S cells and tried t separate cellular components that could possibly be that “transforming principle”. Molecule of DNA gave positive result in a chemical test and also when enzymes able to degrade DNA were introduced, the transforming activity was eliminated.
The electrons generated from the Krebs Cycle are transferred to NAD+ and then sent to the Electron Transport Chain.
The Kreps cycle is part of cellular respiration. Cellular respiration takes place inside the mitochondria. The main purpose of the mitochondria is to convert glucose into energy that the cell can use. <span>The Krebs Cycle is a never-ending cycle which keeps on repeating itself to produce ATP and gives off CO2. </span>
The Electron Transport Chain is the mechanism used by the cell for obtaining energy from sunlight during the photosynthesis process.
