Mitochondrial Physiology Laboratory


Course Description

Students will perform experiments to evaluate mitochondrial content and function using spectrophotometry, histology, and electrophysiology to reinforce concepts discussed in the corequisite course Skeletal Muscle and Mitochondrial Physiology.

Additional Requirements for Graduate Students:
Graduate students are required to give a research presentation for the lab portion proposing how their research could be integrated with the laboratory techniques they are learning in the lab section. Additionally, graduate students will have a final laboratory practicum exam in which they will be presented with a research question and must identify the appropriate laboratory technique, control groups, and methodology.
