The intrinsic rate of the atrioventricular av bundle is 40 to 60 beats per minute (bpm).
<h3>
What is the Atrioventricular (AV) and the intrinsic rate?</h3>
Atrioventricular (AV) can be regarded as the block that usually altered the interruption of impulse transmission between the atria to the ventricles.
And this have the 40 to 60 beats per minute (bpm) as the intrinsic rate.

Answer: Option B
The enzyme has changed shape because of high temperature.
Explanation:
Enzymes are biological catalysts in living organisms that speed up the rate of chemical reactions.
High temperature changes the shape of enzymes.
Increase or high temperature lead to decrease in enzymes activities. This is due to enzyme protein been denatures by high temperature which is the breaking of molecular bonds within the enzyme protein. When the enzymes bonds are broken, the shape of the enzymes changes and they no longer act as catalysts.
