The red line represented the chemical reaction without the enzyme, and the black line represents the activation energy with the enzyme in what way does the addition of the enzyme effect the chemical reaction?​

the correct answer is 4) heat and pressure

metamorphic rocks arise from transformation of existing rocks types, in a process called metamorphism. during metamorphism the original rock(prolith) change into metamorphic rock by heating (150-200c) and pressure of more than 1000 bar. the original rock can be sedimentary, igneous, or existing metamorphic rock.
