If you have a cell with more salt outside the cell, then inside the cell what will happen to the cell?
hodyreva [135]

Answer:

The cell would lose the water inside it causing it to die.

Explanation:

Water in cells moves towards the higher concentration of salt so if there is more on the outside the water would move on the outside causing it to die because it needs water. If it was the opposite and there was more salt inside more water would go inside causing the cell to swell and virtually exploding and diluting parts of our body.

During a laboratory experiment, you discover that an enzyme-catalyzed reaction has a G of -20 kcal/mol. If you double the amount
luda_lava [24]

Answer:

-20 kcal/mol (It stays the same)

Explanation:

Enzymes will reduce the Gibbs free energy of activation, but will neither increase or decrease the free energy of reaction.

Enzymes means of activity is by decreasing the activation energy (Ea or ΔG✳) for a reaction. This in turn raises the reaction rate.

Free energy of reaction

= free energy of product - free energy of substrate

The free energy of the product remains constant even without the enzyme. Hence, the enzyme would show no effect on the free energy of the reaction.

The attached image shows the effect of changes in enzyme concentration on the free energy.
