released
removal hydrogen atoms
used
addition of hydrogen atoms
CYTOSOL
the internal fluid of the cell
made up of water, salts, organic molecules and many enzymes that catalyze reactions (aka - the liquid portion of the cytoplasm)
CYTOPLASM
the "molecular soup" in which the organelles are suspended and held together by a fatty membrane within the plasma membrane of a cell and surrounds the nuclear envelope and the cytoplasmic organelles

the ANAEROBIC BREAKDOWN of a 6-carbon GLUCOSE molecule into two 3-carbon PYRUVIC ACID units
During gylcolysis _____ are lost and join with NAD to form _____.
2 hydrogen atoms
NADH2
REDUCTION
the ADDITION of HYDROGEN atoms
Although some energy is used in the process, what is the overall net gain of glycolysis?

3
glucose
Acetyl CoA is a ____ carbon atom formed from ______
2

CO2
The KREBS CYCLE takes place in the ____ of the mitochodria.
MATRIX
The KREBS CYCLE is the _____ and requires _____
AEROBIC
OXYGEN
What is the first step of the KREBS CYCLE?
ACETYL CoA (2C) + 4C compound = Citric Acid (6C)
What is the second step of the KREBS CYCLE?
Citric Acid (6C) - CO2 - 2H = 5C compound
During the KREBS CYCLE one Pyruvate molecule generates ________.
3 CO2
4 NADH2

NAD
Nicotinamide adenine dinucleotide
the primary energy producers of the cell
MITOCHONDRIA
The MATRIX of the Mitochodria contains ________.
mDNA (mitochodrial DNA), tRNA, ribosomes, and enzymes
How much ATP is produced by the KREBS CYCLE?
NONE - Hydrogens are produced and carried to the inner mitochodrial layer by NADH2 and FADH2
During the third step of the KREBS CYCLE what occurs?
5C compound - CO2 - 2H = 4C compound
What are the last two steps of the KREBS CYCLE?
4C compound - 2H --> 4C compound - 2H --> 4C copmound available to bind with CoA again
What other names is the CYTOCHROME SYSTEM known as?
Hydrogen Carrier System
Electron Transport System
