Multiple Choice

Refer to the graph below. The graph shows results from an investigation using living cartilage cells extracted from slaughtered cows.The cells were treated so that they took up a fluorescent dye in their cytosols without losing viability.(This dye undergoes a change in fluorescence intensity upon binding calcium ions.) The treated cells were then exposed to forces that mimic the forces on cartilage during weight-bearing exercise.This experiment was then repeated with cells that were pretreated with a calcium ion channel inhibitor before exposure to forces of weight-bearing exercise.This inhibitor is specific for intracellular calcium ion channels.Which statement is consistent with the results shown in the graph?

• A) Calcium ions move out of the cytosol into other cell compartments in response to a mechanical stimulus.
• B) Calcium ions are inhibited from moving out of the cytosol into other cell compartments as the result of a mechanical stimulus.
• C) A mechanical stimulus induces cellular changes in cartilage that include the opening of intracellular calcium ion channels.
• D) Extracellular calcium ion channels open as part of the response of cartilage cells to a mechanical stimulus.
• E) Cartilage cells use an inhibitor molecule to prevent intracellular calcium ion release during weight-bearing exercise.
