Cells acquire and use energy to synthesize,store and degrade and eliminate substances through chemical reactions called:

Options

A. metastasis
B. respiration
C. metabolism
D. homeostasis

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks about the chemical reactions through which cells acquire and use energy to synthesize, store, degrade, and eliminate substances.

2. **Identifying Key Terms**: The key terms in the question are "acquire energy," "synthesize," "store," "degrade," and "eliminate." These terms relate to the processes that occur within cells.

3. **Defining Metabolism**: The term that encompasses all chemical reactions in the body that convert food into energy is called "metabolism." Metabolism includes both the breakdown of substances to release energy (catabolism) and the synthesis of substances (anabolism).

4. **Evaluating Other Options**:
- **Metastasis**: This refers to the spread of cancer and is unrelated to energy production.
- **Respiration**: While respiration is involved in energy production, it is a part of metabolism and does not encompass all the reactions mentioned in the question.
- **Homeostasis**: This refers to the body's ability to maintain stable internal conditions and does not directly relate to energy production.

5. **Conclusion**: Based on the definitions and evaluations, the correct answer to the question is **metabolism** (Option C).
