Answer:
Enzymes may require a nonprotein cofactor or ion for catalysis to take speed up more appreciably than if the enzymes act alone;
Enzymes increase the rate of chemical reaction by lowering activation energy barriers.
Explanation:
Some enzymes need a cofactor to act, it is attached to the enzyme and can be nonprotein such as a metal ion. The enzyme function depends on the physical properties of the environmental, especially temperature and pH, each enzyme has a great point of pH and temperature where it has a maximum activity.
If the three-dimensional function of an enzyme is altered, it loses it specified and may not catalyze the reaction, because the structure of the enzyme is responsable for its specified. The catalyst occurs because the enzyme lows the activation energy barriers and this increases the rate of the reaction.

Answer: A. Exothermic reaction
Explanation: Enthalpy change for a reaction is sum of enthalpy of formation of products minus sum of enthalpy of formation of reactants.
When the energy level of reactants is above as compared to the products, the reaction is exothermic and when its opposite then reaction is endothermic.
From given information, the potential energy diagram starts at 380 kJ means the energy level of reactants is 380 kJ. It ends at 100 kJ means the energy of products is 100 kJ.
Enthalpy of reaction = 100 kJ - 380 kJ
Enthalpy of reaction = -280 kJ
Negative sign of enthalpy change indicates an Exothermic reaction.
