Accessing or producing ATP to fuel cellular work OVERALL GOAL: describe the basic ATP producing biochemical pathways in general terms.
Emphasis on the process/results i.e.,"big picture". Memorization of specific intermediates, chemical structures, an
What is behind the term Latin?
original purpose of using the term "Latin" was during the French occupation of Mexico in (1862-1867).
What is the word Caribbean?
region that belongs to Cannibals.

Review glycolysis, TCA, and etransport Fat (lipid) utilization during exercise
Protein utilization during exercise
Describe the cross-over concept:
Recall: ATP is an energetic intermediate
Glycolysis detailed view
Today: More on the interpretation of VO2 data
Establishing a true VO2max?
VE threshold vs Anaerobic threshold vs Lactate threshold vs OBLA Predicting VO2max O2 consumption dynamics (the O2 deficit and O2 debt)-this is mostly chap 7 of your text
The cardiovascular system
Cardio -the heart Vascular- the circulation Functions:
Delivering oxygen and fuels to tissues Removing metabolic waste products It helps maintain pH Temperature regulation Delivers hormones
Function during exercise:
The Pulmonary System
Part I. Lung Structure/Anatomy and mechanics of breathing Major functions of lung: Maintain O2 content of blood Eliminate CO2 Regulate H+
Evaluate lung structure based on its function How does O2 enter the blood? How does CO2 le
Measuring VO2 in the laboratory: Two things will be measured in lab today:
External work (work done on the environment) Internal work (i.e., metabolic work, or energy expenditure).
Open circuit indirect calorimetry (the measurement of VO2). VO2max "
Measuring energy expenditure
The amount of energy that raises one gm of H2O one degree C. Very small unit, thus we report kilocalories (kcal) = 1000 calories.
Example: A snickers bar has about 200 kcal of energy Conversion to Joules: 1 kcal
