Crossing over? That involves the random exchange of chromosomes.
There are 4 electrons altogether shared between carbon atoms in a molecule of C2H4, to be more precise there are 2 electron pairs shared between the carbon atoms.
When the cell gains glucose, the process of glycolysis occurs and then the glucose is broken down into pyruvate.
Now, in pyruvate processing, Acetyl CoA is produced and used in the Krebs Cycle.
During that process, NADH and FADH2 are made and go into the electron transport chain. That is where water and ATP are made.
B) The data will help to generate a new consensus.
Please correct me if I'm wrong!! :)
