Chapter 10.2, Problem 4QC
Summary Introduction
To review:
The functional protein types that are present in a myofibril.
Introduction:
A myofibril is also known as the muscle fiber. It is a rod-like structure and constitutes the basic unit of a muscle cell. The muscles contain tubular cells, which are called myocytes. In striated muscles, the tubular cells are known as muscle fibers. The muscle fibers, in turn, are made up of several chains of myofibrils.

6. This diagram shows rates of oxygen depletion and carbon dioxide accumulation in the blood in
relation to the levels needed to maintain consciousness and trigger the urgent need to breathe in
diving humans.
• How might the location and slope of the O2 line differ for diving marine mammals such as
whales and dolphins?
•
How might the location and slope of the CO2 line differ for diving marine mammals such as
whales and dolphins?
•
•
Draw in predicted lines for O2 and CO2, based on your reasoning above.
How might the location of the Urgent Need to Breathe line and the O2 Blackout Zone line
differ for diving marine mammals?
What physiological mechanisms account for each of these differences, resulting in the ability
of marine mammals to stay submerged for long periods of time?
How much ATP will be produced during the following metabolic scenario:
Aerobic respiration of a 5mM lipid solution that is made up of one glycerol and an 8-carbon fatty acid and 12-carbon fatty acid. Recall that when glycerol breaks down to Glyceraldehyde-3-phosphate it costs one ATP but your get an extra FADH2. Every two carbons of a fatty acid break down to one acetyl-CoA.
Units cannot be entered in this style of question but the units of your answer should be in mM of ATP.
