Asked Oct 24, 2019

Where do the high-energy electrons come from in cellular respiration (what is the source)? Where do the high-energy electrons go in cellular respiration (what is the terminal electron acceptor)?


Expert Answer

Step 1

Cellular respiration is the process in which the energy is harvested from the carbon compound (glucose from food molecule) as they pass through a series of enzyme catalyzed reactions (glycolysis, Krebs cycle and the electron transport chain).

Step 2

Glucose passes through a series of catabolic reactions in the process of cellular respiration.  First, glucose is split in the cytoplasm in the process of glycolysis.   The resulting end-products move into the mitochondria and go through a preparatory step to the Krebs cycle, and finally to the electron transport system.&...
