Question
Chapter 30, Problem 4A
Summary Introduction
Introduction:
The main function of the heart is to pump the blood in the body through the blood vessels. The mammalian heart consists of four chambers, two auricle, and two ventricles, the auricles receive the blood from the body and lungs and the ventricles pump blood to the lungs and body.
Expert Solution & Answer
Answer to Problem 4A
Correct answer:
Option (C).
Explanation of Solution
Explanation/justification for the correct answer:
Option (C) circulatory system. The main function of the circulatory system is to pump the blood in the organism and the heart is the central organ of the circulatory system. The given system represents the heart with a series of blood vessels. Hence, the correct answer is option (C).
Explanation for incorrect answer:
Option (A) excretory system. The excretory system consists of kidney, urinary bladder and other tubes, this system does not represent any of these organs. Hence, it is an incorrect answer.
Option (B) skeletal system. The muscles and the bones together form the skeletal system of the body. Hence, it is an incorrect answer.
Option (D) reproductive system. The reproductive system consists of either male gonads or female gonads. The illustration does not indicate the presence of gonad. Hence, it is an incorrect answer.

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.
