Week 07 - Aerobic Energy Systems Flashcards
Where does AEROBIC glycolysis occur?
In the cytosol
What is the last product of aerobic glycolysis?
Pyruvate (does not go to lactate)
Can NADH+H+ move across mitochondrial membranes?
No
How does energy get from cytosol into mitochondria
Active transport (via glycerol-3-phosphate shuttle)
NADH+H+ outside the mitochondria becomes equivalent to _____
FADH2 in mitochondria
Does the Pyruvate Dehydrogenase Reaction have high or low ΔG
High ΔG (possible high control point)
Lipolysis involves two lipase enzymes..?
- Triacylglycerol lipase
2. Monacylglycerol lipase
FFA after lipolysis (4 steps)
- FFA activation
- Into mitochondrion
- Beta oxidation pathway
- Glycerol use for energy (CHO pathway)
Can FFA cross 2 mitochondrial membranes?
No
FFA Activation takes FFA and converts it to _____
Acyl CoA (not Acetyl CoA)
If the acyl CoA has >14 Carbons in it it can cross the ____ membranes but not the ____ membrane
Outer membrane but not the inner membrane
If FFA has 14+ Carbons it needs to use ______ as a carrier
Carnitine
Beta oxidation occurs in rounds, it shortens chain by ____ each round
2 Carbons
Each round of Beta oxidation gives you (4)…
- acyl CoA
- acetyl CoA
- FADH2
- NADH+H+
Glycerol from lipolysis gets converted into ________ by liver
glycerol-3-phosphate (by glycerol kinase)
glycerol phosphate dehydrogenase take glycerol-3-hydrogenase and converts to _________
dihydrogenase phosphate (intermediate)
This process uses NADH and FADH2 to produce ATP
oxidative phosphorylation
This process begins with the production of Acetyl-CoA
krebs cycle (TCA)
Oxidative phosphorylation is also known as:
electron transport chain
The final electron acceptor during oxidative phosphorylation is:
Water
Which process produces the most ATP?
oxidative phosphorylation
Which of the following is necessary for oxidative phosporylation to occur?
CO2
Products of the krebs cycle (3)?`
ATP, NADH & FADH
