Determine how reaction rate (velocity) varies with substrate concentration. Rate increases Rate decreases Rate is unchanged Additional substrate is added when substrate concentration is high but is not yet saturating. Additional substrate is added when substrate concentration is low. Substrate is added when enzyme is saturated with substrate. Answer Bank © Macmillan Learning Reaction velocity Determine which of the graphs represents the relationship of reaction rate (velocity) and substrate concentration when the enzyme concentration of the non-allosteric enzyme is constant. Substrate concentration Answer Bank

Catalysis through proximity and orientation effects involves: (select all that applies) Group of answer choices binding of acidic and/or basic groups in the binding site facilitating chemical reactions by binding substrates close to specific groups binding of substrate in specific, restrictive orientations depending on metal ions for catalysis

Condition: heat What molecule is the enzyme, what molecule is the substrate, and what molecules are the products? Enzyme: Substrate: Product:

Describe the specific multi-enzyme example discussed in class of how enzyme activity can be altered by changing its substrate to product ratio.
