Which of the following is the best explanation for the inability of a specific animal cell to reduce the Ca²⁺ concentration in its cytosol compared with the extracellular fluid?
A)blockage of the synaptic signal
B)loss of transcription factors
C)insufficient ATP levels in the cytoplasm
D)low oxygen concentration around the cell
E)low levels of protein kinase in the cell

Question

Quizplus · Accepted Answer

Reducing the Ca²⁺ concentration in the cytosol requires active transport processes that are ATP-dependent. Insufficient ATP levels in the cytoplasm would result in the inability to carry out these processes, thus preventing the cell from reducing the Ca²⁺ concentration in its cytosol compared with the extracellular fluid.
