A characteristic of the open-loop system is that it does not use feedback to determine if its output has achieved the desired goal of the input. This means that the system does not observe the output of the processes that it is controlling. Closed-loop systems employ feedback and a reference of correctness. Deviations from the norm are detected and corrections made in order to maintain a desired output.
3) The image shown above is the Carbon cycle. What kind of system is the Carbon cycle?
A) open-loop system
B) closed-loop system
C) unregulated system
D) unchecked feedback system
not graded
Two Acetyl-coA molecules released from a fatty acid enter the Krebs cycle, and can produce six NADH molecules and two FADH2 molecules. These reduced coenzymes can be used to generate:
a) 28 ATP
b) 22 ATP
c) 12 ATP
d) 6 ATP
e) 4 net ATP
How does the “investment phase” of glycolysis effect the net yield of ATP in that pathway?

- What is substrate-level phosphorylation? When does it occur during the breakdown of glucose to CO2?arrow_forwardWhy would a larger surface-area-to-volume ratio decrease metabolicefficiency?arrow_forwardRefer 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_forward
- I'm studing Cellular Respiration. We did a lab. We had technical difficulties... our CO2 gas sensor wasn't working properly. So I am curious, what trends SHOULD I have seen. We compared the CO2 output of bean sprouts vs mealworms. We tested at both room temp (27 degrees C) vs cold temp (15 degrees C) for both the mealworms and bean sprouts. I need to know the trends I should have seen, ie. does an animal or plant produces more C02 and why? Also does the the cool temp make the reduction in CO2 production? Thank you.arrow_forwardDiscuss the effects of the following factors in the rate of cellular respiration: a. temperature b. substrate availability c.woundingarrow_forwardHow can estimation of energy flow from plant to herbivore be correlated to laws of thermodynamics?arrow_forward

D) NAD+ accepts electrons. E) All of the above are correct.arrow_forwardReferencing the image above, you are designing an experiment to determine which food source your yeast utilizes best (flour or glucose). You know that yeast will use the enzyme zymase to digest the substrate to create CO2 via anaerobic respiration and you can capture and measure the CO2 with the balloons. Write hypotheses that you could use to test which food source the yeast prefer. H0: HA:arrow_forward
