Chapter 7, Problem 21RA
Summary Introduction
To review:
Action potential conduction by unmyelinated axons.
Introduction:
Axons transmit the action potential from the axon hillock to the end of the axon till it reaches the dendrites of another neuron. Unmyelinated axons do not have a myelin sheath covering them and the process of depolarization and repolarization occurs across the entire axon membrane. The action potential is conducted due to the cable properties of the axon which can conduct charges.

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.
If a bacterium using aerobic respiration was to degrade one small protein molecule into 8 molecules of pyruvic acid, how many ATP would that cell make? Assume there is no other carbon source.
Units cannot be entered in this style of question but the units of your answer should be in molecules of ATP.
If a bacterium using aerobic respiration was to degrade a 30 mM solution of citric acid, how many ATP would that cell make? Assume no other carbon source is available.
Units cannot be entered in this style of question but the units of your answer should be in mM of ATP.

The researcher chooses randomly 400 women to participate in this experiment for 9 months of their pregnancy period. They all need to have the same diet. The researcher designs two groups of 200 participants: One group take the real medication intended to reduce heartburn, while the other group take placebo medication. In this study what are: Independent variable: Dependent variable: Control variable: Experimental group: " Control group: If the participants do not know who is consuming the real pills and who is consuming the sugar pills. This study is It happens that 40% of the participants do not find the treatment helpful and drop out after 6 months. The researcher throws out the data from subjects that drop out.
