Summary Introduction
To discuss:
The process of how Parkinson patients respond to Valsalva maneuver and how this relate to a common condition in Parkinson patients called orthostatic hypotension, in which blood pressure falls suddenly when the person stands up, leading to dizziness and fainting.
Given:
Recent research indicates that Parkinson disease damages the sympathetic division of the peripheral nervous system. One test for sympathetic division function, called the valsalva maneuver, requires the patient to blow against resistance. A functional nervous system will compensate for the decrease in blood output from the heart by constricting blood vessels.
Introduction:
Valsalva maneuver (VM) was described by Anton Maria Valsalva which he described as the act of the forceful inspiration against a closed glottis after the process of full inspiration. There are several studies related to the complication of cardiovascular changes with respect to Valsalva maneuver

The lipid is composed of one glycerol molecule connected to two fatty acid tails. One fatty acid is 12 carbons long and the other fatty acid is 18 carbons long in the figure below. Use the information below to determine how much ATP will be produced from the glycerol part of the lipid. Then, in part B, determine how much ATP is produced from the 2 fatty acids of the lipid. Finally put the NADH and ATP yields together from the glycerol and fatty acids (part A and B) to determine your total number of ATP produced per lipid. Assume no other carbon source is available. 18 carbons fatty acids 12 carbons glycerol . Glycerol is broken down to glyceraldehyde 3-phosphate, a glycolysis intermediate via the following pathway shown in the figure below. Notice this process costs one ATP but generates one FADH2.
