In the electron transport chain, protons are pumped from the <u>mitochondrial matrix to the intermembrane space</u>, and oxygen is reduced to form water.
The energy derived from the transfer of electrons through the electron transport chain is used to pump protons, as a result, an electrochemical gradient is generated, consisting of a proton gradient and a membrane potential.
The energy created by the formation of this gradient is then harnessed to form ATP as the protons travel down their gradient into the matrix through the ATP synthase channel.
The electron transport and ATP production occur simultaneously and are tightly coupled.

Answer:
The correct answer is: β1 adrenergic receptor activation. Increased in cAMP lead to increased amounts of Na influx (though if channels) and calcium influx of pacemaker cells. This increases the frequency of APs of the pacemaker and increases the rate of contraction.
Explanation:
cAMP generated in response to β1 adrenergic receptors,results in excitation contraction coupling by initiating PKA and causing phosphorylation of L type Ca2+ channels and ryanodine receptors. This increases the concentration of intracellular Ca2+ ions in atrial cells, ventricular cells and AV pacemaker cells. This increase in firing rate. As a result rate of contraction increases.
