Why can’t an enzyme use an induced fit mechanism to achieve catalytic perfection?

Is the following statement correct or incorrect? It is only possible to employ enzymes that are present naturally in yeast or bacteria for biocatalysis.

Knowing that for a bacterial colony to be able to grow it must produce product "3" AND "4", use the information in the image to describe which enzyme(s) are that are Non-Functional in Colony C? Please note error in enzyme description at bottom of image. X converts 1 into 2; Y converts 1 into 3; and z converts 2 into 4.

Can you explain the following based on its mode of enzyme kinetics:  1) Synthesis/degradation of enzymes 2) Allosteric regulation  3) Covalent modification

what is the properties of an enzyme that make it a good biological catalyst?

Catalysis involves overcoming the activation energy barrier of a reaction. What are three ways by which enzymes can do this?

Although we have introduced catalytic strategies separately, an enzyme typically employs more than one during a reaction. The catalytic strategies employed by serine protease include: Select one or more: O a. reduction of ASt b. transition state stabilization Oc. metal-assisted catalysis O d. acid/base catalysis O e. covalent catalysis
