In an experiment, the enzyme lactase is added to milk in a test tube. the products obtained are glucose and galactose. which of these correctly explains the function of the enzyme in this reaction?
a) the enzyme molecules collide with the substrate and break it into simpler products.
b) the enzyme has active sites where the substrate binds with the enzyme to form a complex.
eliminate
c) the substrate binds at the non-active sites of the enzyme, where it is broken down into simpler compounds.
d) the substrate breaks the bonds of the enzyme, resulting in the formation of simpler products.

Agenetically engineered corn plant is approved for agricultural use. the plant produces pollen that can make its own toxins. these toxins protect the corn plant against pests and no longer require the application of chemical pesticide. what is a likely impact on the farmer of growing such a variety of corn? a- the financial costs for the farmer would be lowered since less crops would be lost to pests. b-the financial costs for the farmer would be lowered since more crops would be lost to pests. c-the farmer may be held responsible for increasing chemical pollution. d-the farmer's expenses for pest control would increase due to an increase in bee population.
