- You are talking with a winemaker about yeast. "I know that yeast can survive under both aerobic and anaerobic conditions," he says, "but what I don't understand is why they seem to need so much more sugar under anaerobic conditions. I think they gobble a hundred times as much sugar." Can you explain to him why yeast might need more sugar under anaerobic conditions than under aerobic conditions? Is his estimation of a hundred times as much sugar reasonable?arrow_forwardWhat is the relationship between Cyanobacteria and the chloroplast of phytoplankton (algae)?arrow_forwardWhich definition is INCORRECT? A) O Photoexcitation: light absorption leads to raising an electron to a higher energy state. C) O Photolysis: light absorption coupled to splitting a molecule. D) O Photophosphorylation: a form of substrate level phosphorylation used for ATP formation E) O Photosynthesis: is often photoexcitation and photolysis coupled with CO2 fixation and biosynthesisarrow_forward

To identify the molecule that accepts CO2, Calvin and Benson manipulated the carbon fixation cycle by either cutting off CO2 or cutting off light from cultures of photosynthetic algae. They then measured the concentrations of various metabolites immediately following the manipulation. How would these experiments help identify the CO2 acceptor? a) The CO2 acceptor concentration would decrease when either the CO2 or light is cut off. b)The CO2 acceptor concentration would decrease when the CO2 is cut off but increase when the light is cut off. c)The CO2 acceptor concentration would stay the same regardless of the CO2 or light. d)The CO2 acceptor concentration would increase when either the CO2 or light is cut off. e)The CO2 acceptor concentration would increase when the CO2 is cut off but decrease when the light is cut off.arrow_forwardIf photosynthesizing green algae are provided with CO2 containing heavy oxygen (18O), later analysis will show that all of the following molecules produced by the algae contain 18O EXCEPT a) ribulose bisphosphate (RuBP) b) glyceraldehyde 3-phosphate (G3P) c)O2 d)3-phosphoglycerate e)glucosearrow_forward
