Glycolysis takes in one molecule of glucose (6C), and produces two molecules of pyruvate (3C). This requires the energy from the conversion of 2 molecules of ATP to 2 molecules of ADP.
This process releases energy in the form of 4 molecules of ATP (from ADP) and 2 molecules of NADH (from NAD+)
The electron transport chain (ETC) uses 1 molecule of NADH and 1 molecule of FADH2 (produced in the Kreb's cycle, the stage between glycolysis and the ETC), as well as one molecule of oxygen.
The ETC generates NAD+, 32 molecules of ATP, as well as water as a byproduct.
Gel electrophoresis is a process or a technique in which fragments of DNA are separated in terms of their sizes.
<em><u>The restriction enzyme is mixed with a DNA sample before the process. The restriction enzyme cut DNA at specific points into fragments which can then be separated based on their sizes on an agarose gel.</u></em>
When current is applied to the gel DNA move towards the positively charged electrode since DNA is negatively charged, with shorter fragments migrating faster through the gel in comparison with large fragments.
