A proton gradient is created during the electron transport chain using the energy released from the oxidation of NADH and FADH2. The protons then cross the membrane through ATP synthase down their electrochemical gradient, and ATP is produced. This is an example of
A) energy coupling
B) cotransport
C) allosteric regulation.
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?
In one of the steps of glycolysis, the enzyme pyruvate kinase catalyzes the conversion of phosphoenolpyruvate to pyruvate; the phosphate group from phosphoenolpyruvate is transferred to ADP to
form ATP during the reaction. This process is an example of:
A) O ATP synthesis by substrate-level phosphorylation
B) O coupling an energy releasing process to an energy requiring process
C) O oxidative phosphorylation
D) OB and C are correct
E) OA and B are correct

- In each of two steps during the "Energy payoff stage" of glycolysis, ATP is generated when an enzyme uses one of the phosphate groups attached to one of the ends of a 3-carbon intermediate molecule to phosphorylate (add a phosphate group) ADP, forming ATP. This mechanism of producing ATP from ADP and a phosphate group is known as: Question 9 options: substrate level phosphorylation redox phosphorylation lactic acid fermentation oxidative phosphorylationarrow_forwardCells can make ATP through aerobic respiration, anaerobic respiration, or fermentation. Which of the following pathways do all three forms of cellular catabolism share? breaking down pyruvate into CO2 through a series of steps reducing pyruvate into lactic acid or acetaldehyde to regenerate NAD+ breaking down a molecule of glucose or other organic fuel into two molecules of pyruvate passing electrons through a chain of proteins to an electronegative molecule to oxidize NADHarrow_forwardThe following image is a schematic of the metabolic processes occurring in a plant contained in a closed container. A=Light Dependent reactions B=Glycolysis C=Light Independent Reactions D=Kreb's cycle E=electron transport chain 2a) Use the figure above to explain the conditions in which the oxygen concentration remains constant in the container. b) 2-carboxyarabinitol-1,5-bisphosphate (CABP) is an inhibitor of the enzyme rubisco.

- Refer to the figure. 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_forwardWhat is the metabolic advantage of a substrate cycle?

- Which term is used to describe a two-phase anabolic pathway in which light energy is converted into chemical energyarrow_forwardDifferent sugars prove to be easier or harder for yeast to metabolize. This affects the amount of energy you can get from each different sugar molecule. The easier the sugar molecule is to metabolize, the higher the energy yield (ie ATP yield).
