Temperature is very significant to the living beings because of

Options

A. kinetic of locomotion depends on temperature
B. kinetic of enzymes depends on temperature
C. high temperature facilitates digestion
D. low temperature facilitates digestion

Answer

**Step-by-Step Solution:**

1. **Understanding the Importance of Temperature:**
Temperature plays a crucial role in the functioning of living organisms. It affects various physiological processes, including enzyme activity, metabolism, and overall organism behavior.

2. **Evaluating the Options:**
The question provides four options regarding why temperature is significant to living beings. We need to analyze each option to determine its validity.

3. **Option 1: Kinetic of locomotion depends on temperature.**
- This statement is incorrect. While temperature can influence the overall activity levels of organisms, locomotion itself is not directly dependent on temperature. Organisms can move regardless of external temperature, although extreme temperatures may affect their energy levels.

4. **Option 2: Kinetic of enzymes depends on temperature.**
- This statement is correct. Enzymes are biological catalysts that facilitate biochemical reactions. Each enzyme has an optimum temperature at which it functions most efficiently. If the temperature is too high, enzymes can denature (lose their structure and function), and if it is too low, their activity decreases significantly. Therefore, temperature is critical for enzyme kinetics.

5. **Option 3: High temperature facilitates digestion.**
- This statement is incorrect. Digestion is primarily influenced by the presence of digestive enzymes and acids, not directly by temperature. While some digestive processes may be affected by temperature, it is not a primary factor.

6. **Option 4: Low temperature facilitates digestion.**
- This statement is also incorrect for the same reasons as option 3. Digestion is not directly facilitated by low temperatures; it depends on enzymatic action and the digestive environment.

7. **Conclusion:**
After evaluating all options, the only correct statement is that the kinetic of enzymes depends on temperature. Therefore, temperature is significant to living beings primarily because it affects enzyme activity.

**Final Answer:**
Temperature is very significant to living beings because the kinetic of enzymes depends on temperature.
