The Basic Steps of an Enzyme-Catalyzed Reaction Are

question 117

Multiple Choice

The basic steps of an enzyme-catalyzed reaction are:

• A) substrate and product combine, forming an S-P complex. The reaction occurs, enzymes are released, and the unchanged substrate is released and recycled.
• B) substrate and enzyme combine, forming an E-S complex. The reaction occurs, products are released, and the unchanged enzyme is released and recycled.
• C) substrate, enzyme, and product combine, forming an S-E-P complex. The reaction occurs, enzymes are released, and the unchanged enzyme is released and recycled.
• D) enzyme and product combine, forming an E-P complex. The reaction reverses, enzymes are released, and the unchanged substrate is released and recycled.

Definitions:

Predetermined Overhead Rate

A rate used to allocate manufacturing overhead to individual units of production, based on estimated costs rather than actual costs.

Volume Variance

A measurement of the difference between the actual production volume and the expected (or budgeted) production volume, affecting the costs incurred.

Variable Component

A cost associated with the production of goods or services that varies with the level of output or sales.

Predetermined Overhead Rate

A rate calculated before the accounting period begins, used to apply manufacturing overhead costs to products by estimating fixed and variable manufacturing overhead costs for the coming period.
