Bisubstrate Reactions

'Ping Pong' reaction is the other name for

• Single displacement bi-substrate reaction

• Single-substrate reaction

• Double-displacement bi-substrate reaction

• Lysine

Distinguishing between ordered sequential and random sequential bisubstrate reactions.Which is more complex to describe kinetically?

• Ordered sequential reactions

• Random sequential reactions

• Both are more complex

• None of these

The first step in any reaction catalysed by an enzyme is the formation of a specific association between the molecules called an______________

• Enzyme-product complex

• Enzyme-intermediate complex

• Enzyme-substrate complex

• All of these

Which are the two types of sequential reactions?

• Ping-Pong reaction

• Ordered sequential reactions

• Single displcement reactions

• Random sequential reactions

An enzyme utilizing a ________kinetic mechanism is one in which one or more products are released before all the substrates bind.

• Ping Pong reaction

• Ordered sequential reaction

• Ternary complex

• Random sequential reaction

An enzyme catalyzing a reaction involving two substrates & yielding two products are termed as_____________

• Multisubstrate reaction

• Monosubstrate reaction

• Bisubstrate reaction

Name the co-enzyme present in the conversion of pyruvate into lactate in anaerobic glycolysis?

• NADPH

• FADH

• Mg 2+

• NADH

State true or false.

In random sequential reaction the substrate & products are bound & then released in a preferred order.

• True

• False

What are the characteristics of an enzyme that catalyzes a reaction through the ping-pong mechanism?

• A product is seen before the second substrate is bound

• Binding of the first substrate causes the enzyme to change into an intermediate form that will bind the second substrate.

• The substrate molecules binds to the active site in a specific order and the products are released in a specific order.

• All of the above

Which are the different types of bisubstrate reactions?

• Nucleophilic reaction

• Ping -Pong reactions

• Single displacement reactions

• All of the above
