Cellular Respiration Flashcards
The first stage occurs in the cytoplasm outside of the mitochondria
Glycolysis
During this stage, enzymes break down glucose into two molecules of pyruvate.
Glycolysis
What is produced during Glycolysis
2 ATP
In this stage, the pyruvates in glycolysis move into mitochondria.
Preparatory reaction
In preparatory reaction, the pyruvates are converted into…
Acetyl-CoA (acetyl coenzyme A)
During this process, more NADH is produced, and CO2 is released.
Preparatory reaction
In this stage, the remaining carbons from the initial glucose are oxidized, releasing CO2
Citric acid cycle
What is produced in the citric acid cycle?
NADH, FADH2, and 2 ATP molecules
FADH2 stands for
Flavin adenine dinucleotide
This is the 4th stage, where most ATP production occurs.
ETC (electron transport chain)
Where is the Electron Transport Chain located?
Inner mitochondrial membrane
Enzyme responsible for ATP synthesis in the ETC?
ATP synthase
What is the role of oxygen in the ETC?
Final electron acceptor
What is the ultimate product of the Electron Transport Chain?
ATP (adenosine triphosphate)
What is pumped across the inner mitochondrial membrane during the ETC?
Protons (H+)
