Compare and contrast aerobic and anaerobic respiration
Both processes include glycolysis. In aerobic respiration oxygen (O2) is needed and in anaerobic respiration no oxygen needed. Aerobic produces 36 ATP; Anaerobic produces 2 ATP.
*There are many ways to compare and contrast these!!!
Aerobic Respiration
Uses oxygen
What is the first step of cellular respiration?
Electron Transport Chain
Occurs on the inner membrane of the mitochondria. All of the electrons (H) from glucose travel to the inner membrane of the mitochondria.
How many ATP are produced by the Kreb cycle for each molecule of glucose?
Which of the part of the cellular respiration process takes place in the cytoplasm?
In what organelle would you find Kreb's cycle and the electron transport chain?
The Mitochondria
What is the main event that occurs in glycolysis?
This process breaks glucose into pyruvate molecules. It produces 2 ATPs for each glucose.
How many ATP molecules are produced in the Kreb's cycle?
How would you describe the electron transport chain?
This process uses energy captured from electrons flowing to oxygen to produce most of the ATPs in cellular respiration
What is needed for aerobic respiration?
Which portion of cellular respiration produces the most ATP?
The Electron Transport Chain (32 ATP per glucose)
During respiration, the electron transport chain occurs in the....
inner membrane of the mitochondria.
Fermentation occurs....?
When oxygen is NOT present in anaerobic cellular respiration.
Where does glycolysis occur?
What does the suffix -"lysis" mean?
To Break
Explain the Kreb Cycle. What happens?
This part of respiration occurs in the matrix of the mitochondria. It releases enough energy to make 2 ATP and 6 CO2.
Where does the Kreb Cycle occur?
The matrix of the mitochondria.
What is a pyruvate molecule?
1/2 of a glucose molecule.
How many pyruvates are produced from ONE glucose molecule?
How many carbons are in glucose?
What is the storage form of energy called?
What is the name for the acronym ATP
adenosine triphosphate
what is the process of converting glucose into energy called?
cellular respiration
In which environment does a cell produce more ATP?
Steps of Anaerobic Cellular Respiration
Glycolysis, Fermentation
Steps of Aerobic Cellular Respiration
Glycolysis, Kreb's Cycle, Electron Chain Transport
Cellular Respiration Formula
C6H12O2 + 6O2 ------> 6CO2 + 6H20 + Energy (ATP)
Anaerobic Cellular Respiration occurs in ...
bacteria, yeast, or muscle cells.
Products of Aerobic Cellular Respiration
6CO2 +6H2O + Energy (ATP)
Reactants of Aerobic Cellular Respiration
C6H12O6 +6O2
Metabolic Rate
How quickly metabolism occurs. This affects how much food an organism needs to eat.
Definition of Cellular Respiration
The process of breaking the chemical bonds of glucose into energy. Breaking chemical bonds releases electrons.
ATP releases energy and becomes....
ADP (Adenosine Diphosphate)
