![**Question 12**
Which of the numbered arrows in the figure points toward a "high-energy" phosphoanhydride bond?
[Diagram Explanation]
The diagram shows a nucleotide structure with the following features:
- A triphosphate group, with arrows numbered 4 and 5 pointing to the bonds between phosphate groups.
- A ribose sugar, with arrow 3 pointing at the carbon-oxygen bond.
- A nitrogenous base, with arrows 1 and 2 pointing at bonds within the base.
**Options:**
- ○ 1
- ○ 2
- ○ 3
- ○ 4
- ○ 5
