the products of the light reactions of photosynthesis that are utilized in the Calvin cycle
atp and nadph
Which events occurs in the light reactions of photosynthesis?
solar to chemical energy. splitting of water, regeneration of atp
When oxygen is released as a result of photosynthesis, it is a direct by-product of
splitting of water
Assume a thylakoid is somehow punctured so that the interior of the thylakoid is no longer separated from the stroma. This damage will have the most direct effect on which processes?
During glycolysis, when each molecule of glucose is catabolized to two molecules of pyruvate, most of the potential energy contained in glucose is
stored ATP in phosphate groups
In the process of carbon fixation, RuBP attaches a CO2 to produce a six-carbon molecule, which is then split to produce two molecules of 3-phosphoglycerate. After phosphorylation and reduction produces glyceraldehyde 3-phosphate (G3P), what more needs to happen to complete the Calvin cycle?
Regeneration of Co2 acceptor (RuBP)
In glycolysis, for each molecule of glucose oxidized to pyruvate what comes from this?
4 atp - 2 used = 2atp (2nadh)
Starting with one molecule of glucose, the energy-containing products of glycolysis
2 atp, 2 nadh, 2 pyruvate
Which sequences correctly represents the flow of electrons during photosynthesis
H20 -adph - calvin cycle
Why is glycolysis described as having an investment phase and a payoff phase?
spends atp, and produces atp
Which kind of metabolic poison would most directly interfere with glycolysis?
agent that mimics structures of glucose, and not metabolized
How many carbon atoms are fed into the citric acid cycle as a result of the oxidation of one molecule of pyruvate
3 ( 2 CO2 are released)
The transport of pyruvate into mitochondria depends on the proton-motive force across the inner mitochondrial membrane. How does pyruvate enter the mitochondrion?
through active transport
Why is glycolysis considered to be one of the first metabolic pathways to have evolved?
present in most organisms, no O2, found in cytosol
Which of the following normally occurs regardless of whether or not oxygen (O2) is present?
Inside an active mitochondrion, most electrons follow which pathway?
calvin cycle - nadh - electron transport chain - oxygen
Which of the following produces the most ATP when glucose (C6H12O6) is completely oxidized to carbon dioxide (CO2) and water?
