A Feature Common to All Control Mechanisms Is

Question

A feature common to all control mechanisms is
A) quorum sensing.
B) phosphorylation cascades.
C) the ability to sense that something inside or around the cell has changed.
D) housekeeping enzymes.
E) increased or decreased gene expression.

Accepted Answer

The ability to sense that something inside or around the cell has changed is a feature common to all control mechanisms. This allows cells to respond and adjust their behavior accordingly. Quorum sensing and phosphorylation cascades are specific types of control mechanisms, while housekeeping enzymes are not always involved in control mechanisms. Increased or decreased gene expression is a common outcome of control mechanisms rather than a feature of the control mechanism itself.
