NURS 3100 Exam 1 Practice

Question: 1 / 400

A nurse is reviewing enzymatic activity that changes a medication to a less active form with a nursing student. The nurse knows the teaching is effective if the nursing student responds that which of the following is an example of this concept?

active transport

Active transport is the movement of substances across a cell membrane against a concentration gradient, requiring energy expenditure from the cell. In this context, it refers to the enzymatic activity that changes a medication to a less active form. The other options are incorrect because they do not involve the process of changing a medication's activity. Diffusion is the passive movement of molecules from an area of high concentration to low concentration. Pharmacodynamics is the study of how a drug affects the body, while pharmacokinetics is the study of how the body affects a drug. These options do not directly relate to the concept of enzymatic activity changing a medication's activity.
