Electricity is added to recharge a battery. What is added to ADP to form ATP?
White raven [17]

Electricity is added to recharge a battery. A third phosphate group  is added to ADP to form ATP.

ATP or Adenosine triphosphate contains adenine, ribose and 3 phosphate groups.

ADP is converted to ATP by the following reaction:

ADP+Pi+energy⇄ATP

The analogy between battery and ATP can be explained as ATP is higher energy form and ADP is lower energy form like charged and uncharged form of the battery. When the terminal or third phosphate is removed from the ATP it becomes ADP and releases energy like a battery. The additional phosphate group when added to ADP forms the ATP molecule like the energy spent by the batteries are recharged by putting in additional energy. Here the additional energy is provided by the third phosphate group.

Tetrahydrofolate is important for the activity of which enzyme?
saul85 [17]

Answer:

GAR and AICAR transformylase

Explanation:

Tetrahydrofolate is essential for purine and pyrimidine synthesis, its deficiency can lead to inhibition of nucleic acid such as DNA and RNA and protein synthesis, which are important for the growth and survival of both normal cells and cancer cells. N-10-formyltetrahydrofolate acts as a donor of  carbon atoms to the actively growing bases. It contribution is mediated by the action of the Glycinamide Ribonucleotide (GAR) transformylase and the N-5-aminoimidazole-4-carboxamide ribonucleotide (AICAR) transformylase.
