1D: Metabolism Flashcards
What is the net ATP production from aerobic respiration?
36 ATP
What might cause an increase in high ammonia levels when fat metabolism fails?
body relies more on protein metabolism and release ammonia as a waste product
What is the rate limiting step in glycolysis?
phosphofructokinase
Which electron carrier is a highly water-soluble protein?
cytochrome c
-most others are mobile and hydrophobic
(T/F) Electron acceptors are oxidizing agents and get reduced
true
Cytochrome C acts as what type of electron carrier?
1-electron carrier
Net ATP production in aerobic cellular respiration
38 ATP per glucose
What are the components of fatty acid?
-long hydrocarbon tail and carboxyl head group
Cori Cycle
lactate produced in muscle converted to glucose by liver and then used by muscles
What does the pentose phosphate pathway produce?
- NADPH
- pentoses (5C sugars)
- ribose-5-phosphate
Products of Krebs Cycle (1 acetyl-CoA)
3 NADH, 1 FADH2, 2 CO2, 1 ATP
What enzymes are involved in each of the 4 complexes of the ETC?
Complex I- NADH reductase
Complex II- succinate dehydrogenase
Complex III- cytochrome reductase
Complex IV- cytochrome oxidase
Can acetyl-coA be used to create glucose?
No-not a precursor for gluconeogenesis
What is a fatty acid comprised of?
carboxyl acid head group and long hydrocarbon tail
Where do bacteria carry oxidative phosphorylation?
plasma membrane
