.Cells use ATP as a source of energy to carry out various functions within the cell. In order for ATP to be useful, a chemical reaction that converts ATP to ADP occurs, releasing energy. Which of the following changes in cellular conditions do you predict would cause a decrease in energy production for the cell?
Answer choices:
A lack of water molecules in the cellÍs mitochondria
A large quantity of oxygen in the cellÍs mitochondria
An abundance of ADP molecules in the cell
An increase in temperature of the cellÍs surroundings

The correct answer is A.

Ans.

ATP molecule is considered as energy currency of the cell that provides energy for all the cellular processes. The ATP molecules store energy in their high-energy phosphoanhydride bonds.

ATP molecule hydrolyzes into ADP into PPi (inorganic phosphate), with the help of water to release energy present in phosphoanhydride bond. When sufficient water is not present in cells, ATP will not convert into ADP and cell would show a decrease in energy production.  

Thus, the correct answer is option). 'a lack of water molecules in the cell's mitochondria.'
