navik [9.2K]

Answer:

A. The muscle would not contract.

Explanation:

The sarcoplasmic reticulum is a specialized smooth endoplasmic reticulum that transmits electrical impulses and is the primary regulator of calcium storage, release, and reuptake. On the other hand, glycolysis and the mitochondria are responsible for cellular ATP production.

In the muscle, the SR and mitochondrial function are interconnected, ATP is used to lower myoplasmic calcium levels during muscle relaxation, this means that muscle contractility is linked to the control of sarcomeric Ca2+ delivery/removal and ATP generation/utilization.<em> If we have a failure to remove Ca2+ from the cytosol by not producing ATP, the muscle will be prevented from relaxation, subsequently there will be a decrease in muscle contraction too.</em>

I hope you find this information useful and interesting! Good luck!

vfiekz [6]

Answer:

There are two possible answers to the question

I) decreasing the pressure of the system

II) decreasing the temperature of the system

Explanation:

Looking at the equation of the reaction, it can be seen that the reaction is endothermic. This implies that decreasing the temperature favours the reverse reaction and more NO2 is produced.

Secondly, decreasing the pressure drives the equilibrium position towards the side having the higher total volume hence decreasing the pressure favours the reverse reaction and more NO2 is produced.
