The relative rate of incorporation of CO 2 by Rubisco under N 2 and under pure O 2 should be described. It should also be decided if O 2 is competitive or uncompetitive inhibitor. Concept introduction: In any enzyme, the activity can be inhibited if any small molecule or ion is bonded to it. This inhibition can be done either irreversibly or reversibly. The competitive inhibitors can resemble with the substrate and so they bind to the active sites of enzyme while the uncompetitive inhibitors do not bind as substrate but it binds to enzyme site simultaneously with substrate. The uncompetitive inhibitors are reversible in nature. When the concentration of competitive inhibitor increases, the higher concentration of substrate is required while in case of uncompetitive inhibitors the concentration of substrate does not increase. Pictorial representation: From the given data; the relative rate of incorporation of CO 2 by Rubisco under N 2 and under pure O 2 could be given as:

Interpretation Introduction

Interpretation:

The relative rate of incorporation of CO₂ by Rubisco under N₂ and under pure O₂ should be described. It should also be decided if O₂ is competitive or uncompetitive inhibitor.

Concept introduction:

In any enzyme, the activity can be inhibited if any small molecule or ion is bonded to it. This inhibition can be done either irreversibly or reversibly.

The competitive inhibitors can resemble with the substrate and so they bind to the active sites of enzyme while the uncompetitive inhibitors do not bind as substrate but it binds to enzyme site simultaneously with substrate. The uncompetitive inhibitors are reversible in nature.

When the concentration of competitive inhibitor increases, the higher concentration of substrate is required while in case of uncompetitive inhibitors the concentration of substrate does not increase.

Macmillan Learning Cholesterol synthesis begins with the formation of mevalonate from acetyl CoA. This process activates mevalonate and converts it to isopentenyl pyrophosphate. Identify the atoms in mevalonate and isopentenyl pyrophosphate that will be labeled from acetyl CoA labeled with 14C in the carbonyl carbon. Place 14C atoms and C atoms to denote which carbon atoms are labeled and which are not labeled.
