Cellular Respiration/Aerobic Metabolism
Self-Assessment Worksheet
Human Biology


Directions: Complete each one of the following sections as directed.


A. Summary of Cellular Respiration/Aerobic Metabolism Stages: For each one of the following
events, state if it appropriately describes glycolysis, the transition reaction, the citric acid/Krebs
cycle, and/or the electron transport chain/phosphorylation


Event Relevant Stage(s)

P s
High energy electrons are passed down a series of Electron transport
molecules embedded in the mitochondrial membrane chain (ETC)

Glucose is the starting molecule Glycolysis
Transition reaction;
Carbon dioxide is released Krebs Cycle
Glycolysis, Krebs
