What is the purpose of glycolosis?
To release usuable energy from glucose to power cell work
What is the fate of pyruvate?
To be trasnported to a mitochondrion to be oxidized and used in the Krebs cycle
What are the products of the Krebs cycle (Citric Acid Cycle)?
ATP, NADH, and FADH2
How is energy released from ATP?
The dephosphorylation of ATP into ADP releases energy
What is required for glycolosis to turn glucose into pyruvate?
2 ATP
What are the products of glycolosis
Pyruvate, NADH, and ATP
What comes after the Krebs cycle?
The ETC chain
How much ATP is generated from the Krebs cycle and ETC chain?
Up to 36 ATP
At which point is there a decision between having reactions with or without the presence of oxygen?
After pyruvate is formed
Where and how is pyruvate transported?
From the cytosol, through the mitochondrion, and into it’s matrix through active transport
What happens to pyruvate after it’s transported to the mitochondrions matrix?
It get’s oxidized and enters the Krebs cycle
What happens in the Krebs cycle?
A pathway involving many key reactions in which carbon dioxide is released from organic intermediates, and high energy electrons are transported to NADH and FADH2, and ADP is phosphorylated to turn into ATP
What happens to the electrons that are extracted from glycolosis and the Krebs cycle?
They are transported to the ETC.
NADH from glycolosis, and NADH and FADH2 from the Krebs cycle are donated to the ETC and are then transferred between membrane protiens
What does the ETC do after recieving and passing the electrons between its membrane protiens?
It creates an electrochemical gradient of protons (hydrogen ions) across the inner mitochondrial membrane
What does fermentation allow for?
It allows for glycolosis to proceed in the absence of oxygen
