Tissue respiration denotes

Options

A. Respiration denotes
B. Gaseous exchange between cell and tissue fluid
C. Cell respiration
D. Both B and C

Answer

**Step-by-Step Solution:**

1. **Understanding Tissue Respiration:**
- Tissue respiration refers to the processes that occur within tissues to produce energy. It involves the biochemical reactions that convert nutrients into energy, primarily in the form of ATP.

2. **Identifying the Options:**
- The question provides four options:
- A) Respiration
- B) Gaseous exchange between cells and tissue fluid
- C) Cell respiration
- D) Both B and C

3. **Analyzing Each Option:**
- **Option A:** "Respiration" is too vague and does not specifically refer to tissue respiration.
- **Option B:** "Gaseous exchange between cells and tissue fluid" is a correct description of part of tissue respiration, as it involves the exchange of gases (like oxygen and carbon dioxide) between cells and their surrounding fluid.
- **Option C:** "Cell respiration" is also correct, as it refers to the metabolic processes that occur within cells to produce energy.
- **Option D:** "Both B and C" combines the correct aspects of options B and C.

4. **Conclusion:**
- Since both options B and C accurately describe aspects of tissue respiration, the correct answer is option D: "Both B and C."

**Final Answer:** The correct answer is D) Both B and C.
