A biological steady state:

A. maintains reactions at chemical equilibrium within the cell.

B. is maintained by adjustments in metabolic flux. is a reversible state of the system.

C. allows turnover (utilization and reproduction) of biomolecules while maintaining a constant concentration of biomolecules.

D. is reversible state system

1. all of above

2. A, B and D

3. B and D

3. B and D

Explanation:

1. Steady State: A system that is in a steady state, remains constant during a long time, it requires continual work.

2. It also known as a "system in dynamic equilibrium".

3. A system if it is in a steady state then it has a higher level of energy than its surroundings.

4. A biological steady-state or dynamic equilibrium is when the concentration in a biological system such as a cell is constant but reactions are occurring.
