Term
Where does Glycolysis Start?
Definition
Glucose
Term
What are the end products of glycolosis?
Definition
2 Pyruvic Acids
2 NADH
Net 2 ATP
Term
Where does Glycolosis take place?
Definition
In the cytosol
Term
What is the first stage of glycolosis?
Definition
Sugar Activation (uses 2 ATP)
Glucose is phosphorylated to fructose 1-biphosphate
Term
What is the second stage of Glycolosis?
Definition
Sugar Cleavage, split into 2 3-Carbon Fragments
Term
What is the last (3rd) stage of Glycolosis?
Definition
Sugar oxidation, oxidation due to loss of H to NAD, and 4 ATP molecules formed through loss of P by each 3 carbon fragment; these are now pyruvic acids
Term
Substrate Level Phosphorylation and Anaerobic
Definition
Glycolosis
Term
What has to be present in order for pyruvic acid to move into transitional phase?
Definition
O2
Term
What happens if 02 is not present in the pyruvic acid?
Definition
It becomes Lactic Acid
Term
What are the three steps of the Transition Phase?
Definition
1. Decarboxylation
2. Oxidation
3. Formation of ACetyl Co A
Term
In the first step to the transition phase... What is the function of Decarboylation?
Definition
One Carbon Removed, for the first time we have Co2 as Product
Term
In the second step to the transition phase... What is the function of Oxidation?
Definition
Remaining 2C Fragment has H removed to NAD
Term
In the third step to the transition phase... What is the function of Formation of Acetyl Co A?
Definition
Now Krebs Cycle can begin
Term
Is the Transition phase part of the krebs cycle? And is it neccesary for krebs cycle to happen?
Definition
YEs
Term
What starts the Krebs Cycle?
Definition
Acetyl- Co A
Term
What are the end products of the Krebs Cycle?
Definition
3 NADH,
1 FADH,
2CO2,
1 ATP
Term
Where does the Krebs Cycle take place?
Definition
Mitochondrial Matrix
Term
Substrat Level Phosphoyrlation and AEROBIC
Definition
Krebs CYCLE
Term
Where does the electron transport chain start?
Definition
NADH's & FADH's
Term
What are the end products of the electon transport chain?
Definition
28 ATP, h20
Term
Where does the electron trasport chain take place?
Definition
Mitochondrial Membrane/ Cristae
Term
Where does NADH+H and FADH2 (from glycolosis and the Krebs Cycle) drop off their H's at??
Definition
The inner mitochondrial membrane/cristae
Term
In the Electron transport chain protons and electrons are split apart, and the electrons are shuttled along the membrane from one complex to another....
Definition
protein I, III, IV
Term
While the protons are moved out into the intermembrane space this creates an ______
Definition
Electrochemical gradient
Term
IN the electron transport chain... Electrons are ultimately to Deliver O in order to make ____
Definition
h20
Term
IN the electron transport chain... Protons are pumped back across the membrane by ____ which creates an electrical current that powers ________________
Definition
ATP synthase

Phosphorylation of ADP to ATP
Term
Because Oxygen is directly used and linked to electrons to make water, oxygen is: __________ and the process is __________
Definition
Final electron acceptor
Oxidative phophorylation
