Cellular Respiration Flashcards
Three stages of cellular respiration
Glycolysis, Kreb’s Cycle/Citric Acid Cycle, and ETC and Oxidative Phosphorylation
Glycolysis happens in the cytosol and does what
Uses ATP to convert G3P to Pyruvate, making ATP and NADH
Krebs Cycle: what happens
Pyruvate turns into Acetyl Coa. Bunch of reactions, makes CO2, NADH, ATP, and FADH2. ONLY IF CO2 IS PRESENT
Substrate-Level Phosphorylation
Both Glycolysis and C.A.C can make ATP using a kinase to transfer phosphate to ADP
Electron Transport Chain: where do the electrons come from
NADH (made in Glycolysis/ Krebs Cycle) and FADH2 (made in Krebs Cycle)
What pulls electrons through the ETC (CR)
O2
ETC (CR) makes what
H2O, ATP, FAD+, and NAD+
What creates the H+ gradient across the membrane (CR)
Electron transport and pumping of protons
Chemiosmosis
ATP synthesis is powered by the flow of H+ across the membrane
