Bioenergetics and the metabolic pathways of glycolysis, citric acid
cycle, and lipid oxidation




Question:
What are 3 basic phases of breaking down glucose?
Answer:
1. glycolysis (glucose broken down)


2. citric acid cycle (acetyl-coa goes into cycle)


3. ETC (NADH and FADH2 form ETC)

,Question:
Where does glycolysis take place in the cell? where does citric acid cycle?
ETC?
Answer:
Glycolysis- in the cytosol
CAC- in the mitochondria
ETC- in the inner mitochondria




Question:
What is the structure of NADH?
Answer:
Two nucleotides put together




Question:
What is the structure of FADH2?
Answer:
also has a nucleotide

,Question:
What is the delta G under standard conditions for one ATP breaking down
into ADP and Pi? is it spontaneous?
Answer:
-30.5 kJ/mol- spontaneous bec neg delta G




Question:
What are the standard biochem conditions?
Answer:


pH= 7.4


Mg2+ concentration


temp= 25 C

, Question:
What are the basic steps of making ATP?
Answer:
1. glucose and carbs is broken down in the cytosol into acetyl-coa
2. the acetyl-coa moves to the outer mitochondria to enter the citric acid cycle
to make NADH and FADH2, and GTP
3. transporters/integral proteins bring pyruvates, NADH,FADH2 and ADP
into the inner mitochondria to make ETC and make ATP in a process known
as oxidative phosphorylation
4. the ATP is transported out to the cytosol




Question:
How many steps in glycolysis?
Answer:
10




Question:
What are the two phases of glycolysis?
Answer:
1. preparatory (investment)
2. payoff
