What is the role of ATP in the cell?
a
to signal cell death
b
to make all energy disappear
c
to capture energy from sunlight
d
to store energy in the cell
d
to store energy in the cell
d) to store energy in the cell
The correct answer is D) to store energy in the cell.
ATP, or adenosine triphosphate, is often referred to as the "energy currency" of the cell. It plays a crucial role in energy metabolism, storage, and transfer within the cell.
To arrive at the correct answer, we can go through the options:
a) To signal cell death: ATP does not have a direct role in signaling cell death. Cell death is regulated by other cellular processes.
b) To make all energy disappear: This statement is incorrect. ATP is involved in energy storage and transfer, not in making energy disappear.
c) To capture energy from sunlight: While ATP is important in various energy-capturing processes in cells, such as photosynthesis in plant cells, this statement is too specific and doesn't encompass the complete role of ATP.
d) To store energy in the cell: This statement is correct. ATP acts as the primary energy storage molecule within cells. When energy is needed for cellular processes, ATP is broken down to ADP (adenosine diphosphate) and inorganic phosphate, releasing the stored energy.
Therefore, the correct answer is D) to store energy in the cell.
