Respiration Flashcards
Name the 3-carbon molecule that is an intermediate compound in both aerobic and anaerobic respiration?
Pyruvic Acid
What name is given to the biochemical pathway by which this intermediate compound is produced?
Glycolysis
What is produced from the intermediate compound in the muscle?
Lactic acid
What is produced from the intermediate compound when oxygen is not available in yeast
Ethanol
What compound has 6 carbon atoms?
Glucose
What compound has 3 carbon atoms?
Pyruvic Acid
What compound has 2 carbon atoms?
Acetyl coA
Give two functions of water in yeast cells
Solvent and for transport
Suggest an advantage of using ATP as an energy store in cells
High-energy molecule
Name two processes requiring ATP that occur in cells
Photosynthesis, Respiration
Name two substances, other than carbon dioxide, into which pyruvate may be broken under anaerobic conditions in cells
Lactic Acid, Ethanol
What is the name of the two-carbon compound into which pyruvate may be broken down under aerobic conditions
Acetyl Coenzyme A
Describe the fate under aerobic conditions, of Acetyl Co-enzyme A
Enters Krebs Cycle
Make three points concerning Metabolism
- Sum of all the chemical reactions in the body
- Controlled by enzymes
- Anabolic (Adding of small molecules to from large molecules) and Catabolic (Breaking down of large molecules into smaller molecules) are types
Make three points concerning the Krebs cycle
- Second stage of respiration
- occurs when oxygen is present
- ATP is produced
Make three points concerning ADP
- Adenosine DiPhosphate
- Low energy molecule
- ATP formed from ADP + P
Explain the term fermentation
Anaerobic Respiration
Name an organism that is used in industrial fermentation
Yeast
Name a compound which is used as a carbon source in yeast fermentation
Glucose
Give two differences, other than location, between stage one and stage two
Stage one is anaerobic, Stage two is aerobic
Stage one produces small amount of ATP, Stage two produces large amount of ATP
Where in the cell does stage one occur?
Cytosol
Where in the cell does stage two occur?
Matrix of Mitochondria
What term is used to describe respiration in which only stage one occurs?
Anaerobic
Name a chemical end product of Anaerobic Respiration
Ethanol
