When a metabolic disequilibrium is in effect, then only cells continue to function
How do cells avoid reaching metabolic equilibrium?
Cells constantly exchange matter and energy with their surroundings.
Cells exist in a closed system, preventing interaction with the external environment.
Cells utilize feedback inhibition to slow down metabolic reactions, preventing equilibrium.
Cells maintain a static internal environment, independent of external influences.

Non-linked reactions
Heat evolving reactions
Catalysed reactions
In a metabolic pathway, enzyme A catalyzes the conversion of substrate X to intermediate Y. Enzyme B then catalyzes the conversion of Y to product Z. If a mutation in enzyme B renders it completely inactive, which of the following is MOST likely to occur?
Increased production of substrate X.
Accumulation of intermediate Y and depletion of product Z.
No change in the concentrations of X, Y, or Z.
