Cellular respiration is the biochemical pathway by which cells release energy from the chemical bonds of food molecules and provide that energy for the needed processes for life
100
What is glycolysis?
The breakdown (splitting) of glucose in enzymes, releasing energy and pyruvic acid.
100
What is Kreb's Cycle?
Refers to a complex series of chemical reactions in all cells that utilize oxygen as part of their respiration process.
100
What is the Electron Transport Chain?
A sequence of membrane protein that shuttle electrons during the redox reactions that release energy used to make ATP.
200
What are the 3 stages of cellular respiration (in order) ?
1- Glycolysis
2- Kreb's Cycle
3- Electron Transport Chain
200
Where does the Glycolysis stage occur in the cell?
It occurs in the cytoplasm of the cell.
200
Where does the Kreb's Cycle occur?
In the matrix of the mitochondrion.
200
What is the abbreviation of this stage?
ETC: Electron Transport Chain
300
What part of the cell respiration forms water?
Water is formed during the Electron Transport Chain. The electrons pass thru to the end to attach to oxygen to create water.
300
What substances go into the glycolysis?
It requires the sugar molecule and 2 ATP molecules. It does not require oxygen.
300
What substances go into the Kreb Cycle?
Pyruvate (Made from glucose during glycolysis), O2 (Oxygen), H2O (Water) and ATP.
300
What does the ETC require?
It requires oxygen
400
What are the types of cell respirations?
Aerobic & Anaerobic
400
What substances come out the glycolysis?
2 NADH, 2 ATP, and 2 pyruvate
400
What substances come out the Kreb's Cycle?
CO2 and energy in the form of ATP and NADH or NADP.
400
What is comes out (produced) of the ETC?
ATP and water is produced.
500
How many ATP molecules are produced for each glucose molecule used in fermentation?
From one glucose molecule 36 ATP molecules are made.
500
Does glycolysis occur within the mitochondria?
No, glycolysis occurs in the cytosol.
500
Why is the kreb's cycle also named "The final common pathway of Degradation of organic compounds" ?
It's able to generate acetyl CoA from the degradation of lipids and proteins.
500
Where does the Electron Transport Chain occur?
For Eukaryotes the electron transport chain occurs in the inner Membrane of a mitochondria.
For Prokaryotes it occurs in the plasma membrane as prokaryotes do not have mitochondria.
