Practical Exam 2 Flashcards
Where does glycolysis occur
cytoplasm
What are the starting and ending products of glycolysis
Starting: 6 Carbon Glucose molecule
Ending: 2 ATP, NADH, and Pyruvate
Folds in the inner membrane of Mitochondria
Cristae
Soluble enzymes within the inner membrane of mitochondria
Matrix
Where does the Krebs cycle occur
Mitochondrial Matrix
What are the ending products of the Krebs cycle
CO2, 2 ATP, NADH, FADH
Where does the Electron Transport Chain (ETC) occur
Inner Mitochondrial Membrane
What are the ending products of the Electron Transport Chain
34 ATP and Water (H2O)
Form of anaerobic respiration that occurs in yeast
Alcohol Fermentation
Form of anaerobic respiration that occurs in bacteria and mammalian muscle cells
Lactic Acid Fermentation
How does aerobic respiration differ from anaerobic respiration
Aerobic occurs with the presence of oxygen, and produces more energy
What is the balanced equation for aerobic respiration
Glucose + 6O2 —> 6H2O + 6CO2 + Energy (36 ATP)
What is a respirometer
An airtight system to test respiration
Why is potassium hydroxide (chalk) used in a respirometer
To absorb CO2
How does tetrazolium chloride react with live embryo seeds
Electrons pass along the ETC and react with the tetrazolium chloride to change it from clear to red
What factor make some pigments move farther than others on paper chromatography
Different affinities for the solvent
What are the four pigments during paper chromatography
Chlorophyll b, chlorophyll a, xanthrophyll, carotenes
How do you calculate Rf on chromatogram paper
distance solute traveled / distance solvent traveled
Where do light reactions occur
Thylakoid membrane
What are light reactions products
ATP, NADH and Oxygen
Where do dark reactions occur
Within the stroma of chloroplast
What does the calvin cycle produce from CO2
Sugar
Uses chemical energy produced in light reactions to fix carbon
Dark reactions
What organelle does photosynthesis occur
Chloroplast
