Concept explainers
(a)
To explain: The reason why it is necessary for calcium ion channels to be highly specific for Ca2+.
Concept introduction: Calcium ion channels in the endoplasmic reticulum are opened by secondary messengers of the cell signaling cascades. The cytosolic calcium increases. The calcium ion channels on the mitochondria are highly specific for calcium ions.
(b)
To explain: The way in which increased matrix [Ca2+] affects the oxidative phosphorylation.
Concept introduction: Calcium ion channels in the endoplasmic reticulum are opened by secondary messengers of the cell signaling cascades. The cytosolic calcium increases. The calcium ion channels in the mitochondria are highly specific for calcium ions.
