Which of the following statements is true for a molecule that is phosphorylated?
A)It has been reduced as a result of a redox reaction involving the loss of an inorganic phosphate.
B)It has a decreased chemical energy and is less likely to provide energy for cellular work.
C)It has been oxidized as a result of a redox reaction involving the gain of an inorganic phosphate.
D)It has increased chemical potential energy that may be used to do cellular work.

Question

Quizplus · Accepted Answer

When a molecule is phosphorylated, a phosphate group is added to it, which increases its chemical potential energy. This increased energy can be used by the cell to do work, such as powering chemical reactions or transporting molecules across membranes. Therefore, option D is the correct answer. Option A is incorrect because phosphorylation does not involve a redox reaction that results in a loss of inorganic phosphate. Option B is incorrect because phosphorylation actually increases chemical energy. Option C is incorrect because phosphorylation does not involve a redox reaction that results in the gain of inorganic phosphate.
