Question
Chapter 19, Problem 1CRQ
Summary Introduction
Introduction: The heart contracts and relaxes to pump the blood throughout the body. One complete contraction and relaxation is called a heartbeat and the rate of heartbeat is 70 to 75 beats per minute. The heart produces a characteristic sound during the heartbeat.
Expert Solution & Answer
Answer to Problem 1CRQ
Correct answer: The statement “the S1 or lubb sound of the heart is produced by the closing of the AV valves” is true.
Explanation of Solution
The heart produces the “lubb” and “dubb” sound due to the closure of the heart valves. The heart has four valves, two semilunar valves, and two atrioventricular (AV) valves. The mitral valve or bicuspid valve and tricuspid valve are atrioventricular valves situated between atria and the ventricles. The closure of AV valves creates the first sound the S1-“lubb”.

- Aerobic respiration of one lipid molecule. 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.
