In ATP sugar is

Options

A. ribose
B. deoxyribose
C. glucose
D. trioses

Answer

To answer the question "In ATP, sugar is," we need to analyze the components of ATP (adenosine triphosphate) and identify the type of sugar it contains.

### Step-by-Step Solution:

1. **Understanding ATP**: ATP stands for adenosine triphosphate. It is a nucleotide that plays a crucial role in energy transfer within cells.

2. **Components of ATP**: ATP consists of three main components:
- A nitrogenous base (adenine)
- A sugar
- Three phosphate groups

3. **Identifying the Sugar**: The sugar component of ATP is a pentose sugar, which means it has five carbon atoms. There are two types of pentose sugars:
- Ribose
- Deoxyribose

4. **Ribose vs. Deoxyribose**:
- Ribose is the sugar found in RNA (ribonucleic acid).
- Deoxyribose is the sugar found in DNA (deoxyribonucleic acid).

5. **Conclusion**: Since ATP contains ribose as its sugar component, the correct answer to the question is that in ATP, the sugar is ribose.

### Final Answer:
In ATP, sugar is ribose.
