Scrambled Steps of Cellular Respiration
Cut the following steps into strips. Put the following Steps to Cellular Respiration in Order.
Somewhere in the list is the purpose of cellular respiration. Be sure to identify it and put it at
the top of your list next to the hand-written words “Purpose of cellular respiration.”
Glycolysis breaks a 6-carbon molecule in half.
During this process of fermentation, plants produce alcohol, while animals produce lactic
acid. This process only produces 2 ATP.
Two things can happen: If oxygen is present, pyruvic acid enters the mitochondria to enter
the Kreb’s Cycle.
As H+ ions pass back across the mitochondrial membrane through ATP Synthase, molecules
of ATP are made.
From the Kreb’s cycle, NADH and FADHS enter the electron transport chain.
The products are 2 molecules of pyruvic acid (each has 3-carbons).
The process that releases energy by breaking down food in the presence of oxygen.
Each protein in the electron transport chain passes an electron to the next protein and pumps
an H+ ion into the intermembrane space.
If no oxygen is present (anaerobic), pyruvic acid goes through “fermentation.”
In the cytoplasm of a cell, cellular respiration begins.
The final end products of cellular respiration are energy (ATP), H2O, and CO2.
Here in the Krebs’ cycle, pyruvic acid (pyruvate) is converted into CO2, H2O, and 2 ATP.
The electron transport chain takes electrons from NADH and FADH2 and moves them down
the series of proteins.
