Which does not occur in glucose

Options

A. Digestion
B. Ingestion
C. Absorption
D. Assimilation

Answer

To determine which process does not occur in glucose, we need to analyze the options provided: digestion, ingestion, absorption, and assimilation.

### Step-by-Step Solution:

1. **Understanding Glucose**:
- Glucose is a simple sugar and is the primary energy source for the body. It is the end product of carbohydrate digestion.

2. **Analyzing the Options**:
- **Option 1: Digestion**:
- Digestion is the process of breaking down food into simpler forms. Since glucose is already a simple sugar, it does not undergo further digestion. Therefore, digestion does not occur in glucose.
- **Option 2: Ingestion**:
- Ingestion refers to the intake of food. Glucose can be ingested in the form of sugary foods or drinks (like glucose powder). So, ingestion does occur.
- **Option 3: Absorption**:
- Absorption is the process by which nutrients are taken up from the digestive tract into the bloodstream. Glucose is absorbed in the small intestine after digestion. Therefore, absorption does occur.
- **Option 4: Assimilation**:
- Assimilation is the process of utilizing absorbed nutrients in the cells for energy and other functions. Glucose is used in cellular respiration to produce energy (ATP). Thus, assimilation does occur.

3. **Conclusion**:
- Based on the analysis, the process that does not occur in glucose is **digestion**.

### Final Answer:
**Digestion does not occur in glucose (Option 1).**
