Which of the Following is Regulated by Mitochondria

Question

Which of the following is regulated by mitochondria? A)cytosolic levels of chloride ions B)intracellular levels of K⁺ ions C)cytosolic levels of Ca²⁺ ions D)process of closure in endocytosis

Accepted Answer

Mitochondria are involved in regulating the cytosolic levels of calcium ions (Ca2+). They sequester calcium ions from the cytosol and release them in response to cellular signals, which helps in various cellular processes such as muscle contraction, cellular metabolism, and cell signaling. Therefore, option C is the correct answer. Options A, B, and D are not regulated by mitochondria.
