MetP1
What is metabolism?
All chemical reactions of an organism
Potential vs. Kinetic energy?
Potential = stored
Kinetic = in motion
NAD+
Name of organisms that are self-feeders using inorganic compounds?
chemoautotrophs
What is NADP+?
Electron carrier in photosynthesis
2 laws of thermodynamics?
1st law = energy not created nor destroyed
2nd law = energy conversion is not 100% efficient
Catabolic vs. Anabolic reaction?
Catabolic = break molecules down
Anabolic = build molecules up
What is substrate-level phosphorylation?
Adding phosphate group to turn ADP into ATP
Stroma
What is photosystem I and II?
Sites of light absorption
ATP structure?
3 phosphate groups, ribose sugar, and Adenine base
Approx. # of ATP from electron transport chain?
32-36
What is produced out of glycolysis?
2 pyruvate molecules and 2 ATP
What sugar is made during the reduction stage in Calvin Cycle?
G3P
Photosystem II restores electrons by splitting what molecule?
water
Competitive vs. Non-competitive inhibition?
Competitive --> competes for active site
Non-competitive --> binds to alternative (allosteric) site
Where does glycolysis occur and conditions?
Cytosol/Cytoplasm; with and without oxygen
Use 2 pyruvate molecules and break them down further to generate energy
How do you benefit from photosynthesis? How do they benefit from you?
We breathe oxygen that they produce; We breath out CO2 which is an input for photosynthesis.
What is produced out of light-dependent reactions?
ATP and NADPH
Exergonic vs. Endergonic reaction?
Exergonic = releases energy
Endergonic = requires energy
Know big picture of Free Energy (delta G)
What do enzymes do and how do reactants bind?
Enzymes catalyze reactions (lower activation energy) and reactants bind at the active site
What is the first step in the electron transport chain?
Transfer of electrons from NADH and FADH2 which will move down the chain
What is any 1 similarity AND 1 difference between photosynthesis and cell respiration?
Answers vary
Inside the thylakoid and back out through ATP synthase
