ATP or Adenosine Triphosphate is the energy that the cells use to make the body perform properly. Carbohydrate is the preferred nutrient for ATP production in the mitochondria of the cell because it can be easily broken down. When absorbed by the body, carbohydrates automatically turn into glucose and glycogen.

Glucose, as the by-product of carbohydrates, readily provides a supply of energy to the body as it circulates with the blood. Too much glucose in the blood will make the blood sticky and will have a hard time to flow in the blood vessels.

Glycogen on the other hand, is the back-up energy source of the body when glucose is no longer available. It is stored in the muscles and liver. It can readily turn again into glucose when the body thinks it needs it.

step 1: initiation

initiation is the beginning of transcription. it occurs when the enzyme rna polymerase binds to a region of a gene called the promoter. this signals the dna to unwind so the enzyme can ‘‘read’’ the bases in one of the dna strands. the enzyme is now ready to make a strand of mrna with a complementary sequence of bases.

step 2: elongation

elongation is the addition of nucleotides to the mrna strand. rna polymerase reads the unwound dna strand and builds the mrna molecule, using complementary base pairs. there is a brief time during this process when the newly formed rna is bound to the unwound dna. during this process, an adenine (a) in the dna binds to an uracil (u) in the rna.

step 3: termination

termination is the ending of transcription, and occurs when rna polymerase crosses a stop (termination) sequence in the gene. the mrna strand is complete, and it detaches from dna.
