Intro to Biochemistry - Pyruvate, Lactate, ETC

What is the ETC (electron transport chain) for?

For moving H+ into the inter membrane space

What runs ATP Synthase?

The flow of H+ across the membrane ( ETC)

What is the 1st building block of Glucose?

Alanine - can be deaminated into pyruvate

What is the 2nd building block of Glucose?

Lactate - can be oxidized into pyruvate

What is the 3rd building block of Glucose?

Glycerol - can be converted into DHAP

How can ethanol metabolism interfere with gluconeogenesis?

the overproduction of NADH inhibits access to the 3 building blocks

Under what conditions does Pyruvate → Lactate make sense?

anaerobic

Under what conditions does Pyruvate → Acetyl CoA → Citric Acid Cycle make sense?

Aerobic

What is ADP Respiratory Control?

the more ADP, the more synthase → more H+ → more ETC

What is the Cori Cycle?

the idea that tissues other than the liver can send the liver lactate that can convert to glucose, then convert back to lactate

What is the Glucose- Alanine Cycle?

the idea that glucose makes pyruvate through glycolysis to make alanine

Why do we breathe harder when using ATP?

The increased need for ATP requires more oxygen to fuel muscles and remove waste
