Cellular Respiration Flashcards
Cellular Respiration
Is a series of metabolic pathways that releases energy from food and generates a high energy compound called adenosine triposphate (ATP)
ATP
ATP is composed of adenosine and three inorganic phosphate, energy is released from ATP when the bond attached to the terminal phosphate is broken by enzyme activity.
Importance of ATP
It acts as the link between catabolic energy releasing reactions and anabolic energy consuming reactions. ATP is made continuously and does not need storing as it is constantly being used.
Where does Glycolysis occur?
Cytoplasm
What is Glycolysis
The breakdown of glucose to pyruvate
What is the energy investment stage?
2 ATP are invested and 4 ATP is produced (Net 2 ATP)
What is the function of Dehydrogenase
Enzymes remove H+ ions and high energy electrons and pass them to NAD to make NADH
What does pyruvate get broken down into?
Acetyl group
What does the Acetyl group bind with and form?
Binds with coenzyme A and forms acetyl coenzyme A
Where does the Citric Acid Cycle occur
Matrix of the mitochondria
What forms Citrate
Acetyl Coenzyme A and Oxaloacetate
Where does NADH take the H+ ions
Carries them to the Electron Transport Chain
What gas gets released in the Citric Acid Cycle
Carbon Dioxide
Where does the Electron Transport Chain take place?
Inner mitochondrial membrane
What are electrons passed through?
ATP synthesis
