What is cellular respiration?
Process that converts glucose into ATP (energy) in cells
Where does glycolysis occur?
Cytoplasm (cytosol)
What is the main purpose of glycolysis?
Break glucose into 2 pyruvate molecules
What does glycolysis produce (net)?
2 ATP, 2 NADH, 2 pyruvate
What type of phosphorylation happens in glycolysis?
Substrate-level phosphorylation
Where does pyruvate oxidation occur?
Mitochondria
What happens in pyruvate oxidation?
Pyruvate is converted into Acetyl-CoA
What does pyruvate oxidation produce?
NADH and Acetyl-CoA (2 of each per glucose)
Where does the Krebs cycle occur?
Mitochondria
What is the main purpose of the Krebs cycle?
To load electron carriers (NADH and FADH2)
What does the Krebs cycle produce per glucose?
6 NADH, 2 FADH2, 2 ATP, CO2
What is the electron transport chain (ETC)?
A series of proteins that transfer electrons and pump H⁺ ions
Where does the ETC occur?
Inner mitochondrial membrane
What is the main purpose of the ETC?
To create a proton (H⁺) gradient
Does the ETC directly make ATP?
No
