-A glucose molecule
-NADPH
The movement of an electron through an ETC
What type of enrgy is not used in cells?
Heat
Define entropy
The amount of disorder is a system
What is true of a rxn that is catalyzed with an enzyme?
The catalyzed enzyme
What is true reguarding a nucleotide ATP?
Hydrolysis of the bonds that hold phosphate to each other is regularly used to provide to a cell
The ultimate outcome of chemiosmosis is:
Synthesis of ATP
What is the function of the thylakoid disc space of the chloroplast?
The location used to store a high concentration of protons
Which part of the photosynthetic mechanism is responsible for the primary photoevent?
Pigments of the antenna complex
What is the functional relationship betweeen light & dark rxn's?
The light rxn's provide ATP energy and electrons to the dark rxn's
What is the direct energy source for the transport of protons by the b6f complex during the light rxn's?
High-energy electrons
What is the function of photosynthetic rxn centers?
The reduction of the electron transport chain
A Z-diagram is best for summarizing:
Electron energy
A poison that directly inactivated RuBP would affect which step of photosynthesis?
Carbon Fixation
If a researcher wanted to experimentally disrupt photosynthetic ATP synthesis without affecting the electron transport chain, which would he target?
ATP synthase
Of all of teh molecules that participate in the redox rxn's of photosynthesis, which one would be predicted to have the highest electron affinity?
-NADPH
-PGA
-ATP Synthase
-B6f Complex
-Photosystem I
PGA
Which molecule taht participates in carbon fixation is the starting and ending point of the Calvin Cylce?

-CO2
-Glucose
-G3P
RuBP
What is a process that is both photosynthesis and cellular-respiration?
Chemiosmosis
What steps in cellular respiration include a decarboxylation rxn?
The oxidation of pyruvate & the Krebs cycle
Where does the oxidation of pyruvate take place?
The mitochondrial membrane
Which step of cellular respiration is the most energy obtained?
The production of NADH from the Krebs cycle
How are chemiosmosis & glycolysis similar?
The both produce ATP
The process of phospho-creatine donating a phosphate group to ADP is an example of:
Substrate-level phosphorylation
What happens to the electrons harvested thorugh the reduction of NAD+ during teh Krebs cycle?
They enter the ETC and provide energy to pump protons
What energy carrying molecules are produced during glycolysis?
ATP & NADH
How is the ETC related to ATP synthesis?
The ETC provides energy for ATP synthesis
The biosynthesis of which product includes a decarboxylation rxn?
Ethanol
Where do amino acid metabolites used for energy production enter the cellular respiration process?
The Krebs cycle
Beta-Oxidation is a process that is involved in the catabolism of:
Fats
