Which one is false?
I. Energy can enter and leave a cell
II.Matter can enter and leave a cell
III. A cell can use energy from other sources to increase its order and complexity
IV. Metabolic pathways are interlinked
V. Blood concentration of glucose in a normal healthy person is 4.5 -5.0 mm, while that of hormones would be nanogram/mL
VI. Living process is a constant effort to promote falling into equilibrium

Options

A. Only V
B. Only VI
C. Only I and IV
D. Only IV

Answer

To determine which statement is false among the provided options, let's analyze each statement one by one:

1. **Statement I: Energy can enter and leave a cell.**
- This statement is true. Cells can absorb energy in the form of nutrients and convert it into usable energy (ATP) while also releasing energy in various forms.

2. **Statement II: Matter can enter and leave a cell.**
- This statement is also true. Cells can take in substances (like nutrients and water) and expel waste products.

3. **Statement III: A cell can use energy from other sources to increase its order and complexity.**
- This statement is true. Cells utilize energy from food and other sources to build complex molecules and maintain their structure.

4. **Statement IV: Metabolic pathways are interlinked.**
- This statement is true. Metabolic pathways often share intermediates and are interconnected, allowing for efficient energy use and resource allocation.

5. **Statement V: Blood concentration of glucose in a normal healthy person is 4.5 - 5.0 mm, while that of hormones would be nanogram/mL.**
- This statement is true. The glucose levels in healthy individuals typically fall within this range, and hormone concentrations are indeed measured in nanograms per milliliter.

6. **Statement VI: Living process is a constant effort to promote falling into equilibrium.**
- This statement is false. Living organisms strive to maintain a state of non-equilibrium to sustain life processes. If they were to reach equilibrium, metabolic activities would cease, leading to death.

Based on the analysis, the false statement is **Statement VI**.

### Summary of the Solution:
- The false statement among the options provided is **Statement VI**, which incorrectly states that living processes promote falling into equilibrium. In reality, living organisms maintain a state of non-equilibrium to sustain life.
