The vagus nerve fibers carry action potentials from the brain toward the heart.
<h3>What is vagus nerve?</h3>
The vagus is a nerve that performs the role in sensory, motor, and secretory functions. It contains about 80% sensory fibers. The vagus nerves comes from the brain towards the carotid artery of the heart.
So we can conclude that The vagus nerve fibers carry action potentials from the brain toward the heart.

The corect ancer i thank it is c
"Anaerobic process that restores NAD+ supply" describes the process of fermentation.
<u>Answer:</u> Option D
<u>Explanation:</u>
"When oxygen is not present or an organism can not undergo aerobic respiration, pyruvate will be subjected to a process" called fermentation. These do not need oxygen, so is anaerobic. Also, will refill NAD+ formed in glycolysis from NADH + H+.
Although in humans, aerobic conditions generate pyruvate while anaerobic conditions go for lactate formation. There are two major kinds of anaerobic respiration involving alcoholic fermentation and fermentation of the lactic acid. These are not the preferred way to release the energy from the glucose molecules but it is the only alternative to survive when energy is needed.
