In cell signaling, what does the acronym "CADET" refer to?

• A. Receptors and ligands
• B. Factors that influence enzyme activity
• C. Elements that shift the oxygen dissociation curve
• D. Components of the ATP cycle

Answer: (C)

The acronym "CADET" stands for factors that influence the oxygen dissociation curve in hemoglobin. Specifically, it represents Carbon dioxide, Acidity (or pH), 2,3-DPG (2,3-diphosphoglycerate), Exercise, and Temperature. These factors affect the affinity of hemoglobin for oxygen, with shifts in the curve indicating that hemoglobin either releases oxygen more readily (due to increased levels of carbon dioxide, lower pH, elevated temperature, etc.) or holds onto it more tightly. This physiological response is crucial for delivering oxygen to tissues that are metabolically active and producing lots of carbon dioxide and protons, thus ensuring that oxygen supply meets the demand in various tissues during different states of activity. The other options pertain to different concepts in biochemistry and physiology and do not relate to the specific context of the oxygen dissociation curve and its influencing factors as represented by the acronym "CADET."
