Which molecule carries energy inside cells? ( 1 point )
A.) ATP
B.) water
C.) glucose
D.) oxygen
A.) ATP
The molecule that carries energy inside cells is A.) ATP (Adenosine Triphosphate).
The molecule that carries energy inside cells is ATP (adenosine triphosphate). To find the answer, we can go through the options one by one and eliminate the incorrect choices.
B.) Water: While water is essential for various cellular processes, it does not carry energy within cells.
C.) Glucose: Glucose is an important source of energy in cells, but it is not the molecule that directly carries energy. Glucose is broken down through cellular respiration to produce ATP, which is then used to store and transport energy.
D.) Oxygen: Oxygen is involved in cellular respiration and is required for the production of ATP. However, oxygen itself is not the molecule that directly carries the energy.
Therefore, the correct answer is A.) ATP, as it is the primary molecule used by cells to store and transfer energy.
