The Biosphere 2 project, in Tucson, Arizona, was an experiment involving a large sealed terrarium with humans and photosynthetic plants living in balance. Why did the project have to be interrupted after only a few months? Levels of CO2 rose to dangerous levels. The humans ran out of food. The plants stopped producing oxygen. The rate of photosynthesis was too high correct answers Levels of CO2 rose to dangerous levels The __________ is driven directly by photo- ns from the sun in photo...

The difference between an oxidation reaction and a reduction reaction is that oxidation is the _____ correct answers loss of electrons and reduction is the gain of electrons. If the Gibbs free energy change value for a reaction is less than zero, this reaction is ______ correct answers exergonic Flux is defined as the rate at which ___ is/are interconverted. correct answers Metabolites Enzyme active sites... correct answers Are characterized as a pocket or cleft Which answer correctl...

AL 1.1 - what is the difference between actual change in free energy (delta G) and standard change in free energy (delta G knot) with regard to the spontaneity of the cell. correct answers Delta G knot can be used to predict the spontaneity of a reaction under standard conditions, which are 1 atm, 298K and all reactants and products are initially set at [1M]. Under these conditions, the reaction will be spontaneous if delta G knot <0 as defined by. Delta G knot = -RT lnKeq. Under cellular c...

2-phosphoglycerate(2PG) is converted to phosphoenolpyruvate (PEP) by the enzyme enolase. The standard free energy change(deltaGo') for this reaction is +1.7 kJ/mol. If the cellular concentrations are 2PG = 0.5 mM and PEP = 0.1 mM, what is the free energy change at 37 oC for the reaction 2PG ↔ PEP? correct answers -2.4 KJ/mol Which statement below most accurately describes catabolic and anabolic pathways? correct answers Catabolic pathways degrade molecules and anabolic pathways synthesize ...
