Which of the following is formed from phosphorylation ?

Options

A. Fructose 1,6-biphosphate
B. Phosphoglyceric acid
C. PEP
D. Pyruvic acid.

Answer

To solve the question "Which of the following is formed from phosphorylation?" we will analyze each option provided:

1. **Understanding Phosphorylation**:
- Phosphorylation is the process of adding a phosphate group (PO4) to a molecule. This process is crucial in metabolic pathways, including respiration and glycolysis.

2. **Analyzing Each Option**:
- **Option A: Fructose 1,6-bisphosphate**:
- Fructose is converted to fructose 1,6-bisphosphate through the addition of a phosphate group. Therefore, this compound is formed from phosphorylation.

- **Option B: Phosphoglyceric acid**:
- Phosphoglyceric acid is formed from fructose 1,6-bisphosphate, but this conversion does not involve the addition of a phosphate group. Hence, this option is incorrect.

- **Option C: PEP (Phosphoenolpyruvate)**:
- PEP is formed from 2-phosphoglycerate. This conversion does not involve the addition of a phosphate group, making this option incorrect as well.

- **Option D: Pyruvic acid**:
- Pyruvic acid is produced from PEP, and this conversion also does not involve the addition of a phosphate group. Therefore, this option is incorrect.

3. **Conclusion**:
- The only compound that is formed through the process of phosphorylation is **Fructose 1,6-bisphosphate**.

**Final Answer**: Fructose 1,6-bisphosphate is formed from phosphorylation.
