Which option defines ATP?(1 point)
a molecule that allows other molecules to enter and leave a cell
a molecule that allows other molecules to enter and leave a cell
a molecule used in energy transfers within the cell
a molecule used in energy transfers within the cell a molecule that copies genetic information within the cell
a molecule that copies genetic information within the cell
a molecule used to help chemical reactions progress in a cell
a molecule used in energy transfers within the cell
The correct option that defines ATP is:
- A molecule used in energy transfers within the cell
The correct option that defines ATP is:
a molecule used in energy transfers within the cell.
To determine the correct answer, you can break down the acronym ATP, which stands for Adenosine Triphosphate. Adenosine Triphosphate is a molecule that plays a crucial role in energy metabolism in living organisms. It acts as the main energy currency of the cell, providing the energy needed for various cellular processes.
By eliminating the other options:
- The first option mentions a molecule that allows other molecules to enter and leave a cell. This is more related to the function of transport proteins or channels, not ATP.
- The third option suggests that ATP is a molecule that copies genetic information within the cell. This is incorrect as ATP is not directly involved in DNA replication.
- The last option states that ATP is used to help chemical reactions progress in a cell, which is partially true. ATP provides energy for chemical reactions but is also involved in other cellular processes beyond just helping reactions progress.
Therefore, the correct definition of ATP is the second option: a molecule used in energy transfers within the cell.
