Post-Translational Regulation of an Enzyme's Activity,such as Glutamine Synthetase,can Be

question 14

Multiple Choice

Post-translational regulation of an enzyme's activity,such as glutamine synthetase,can be finely controlled at varied levels due to

• A) the varied strengths metabolite-regulating compounds can have with the enzyme such as hydrogen bonding, covalent bonding, and van der Waals attractions.
• B) having multiple independently functional subunits.
• C) the structural strength enzymes have once properly folded compared to short-lived and easily degradable transcripts during translational regulation.
• D) weak chemical modifications of the enzyme rather than harsh protein-protein or protein-DNA interactions.

Definitions:

Levels

Levels refer to the different positions or stages in a hierarchical structure or process, indicating varying degrees of magnitude, importance, or progress.

Efficient Scale

The level of production that minimizes long-term average total costs, resulting from economies of scale without incurring diseconomies of scale.

Marginal Cost

The supplementary cost attached to the output of an additional product or service unit.

Diminishing Marginal Product

The principle stating that as one inputs more of a factor of production while holding other inputs constant, the added output produced from each additional unit of the variable input eventually decreases.
