Answer 5

Under what conditions can aerobic respiration be used as a means to generate the ATP needed to carry out cellular processes?
Oxygen is absent; electron transport chain is not used.
Oxygen is absent; electron transport chain is used.
Oxygen is present; electron transport chain is not used.
Oxygen is present; election transport chain is used.

Answer 6

the last one

Answer 7

D is the correct choice.

The option regarding glycolysis (anaerobic conditions) is totally irrelevant in this case, since the question specifically refers to AEROBIC conditions. By definition, aerobic respiration is a general term denoting ATP production via oxidative phosphorylation, i.e. oxygen present, electron transport chain operating.

Answer 8

Which of the following best describes how ATP synthase is used in the inner membrane of the mitochondrion during the process of chemiosmosis?
It breaks ATP down into ADP and releases energy that can be used to do work.
It converts ATP to ATP by removing an inorganic phosphate group into the cytosol.
It generates ATP from ADP by absorbing energy released by the Calvin cycle.
It uses the energy of a proton concentration gradient to form ATP from ADP.

Answer 11

During the energy investment phase of glycolysis, glucose undergoes chemical reactions to become
FADH2
G3P
NAD+
RuBP

Answer 12

Two chemical reactions are taking place simultaneously in an organism. For Reaction A, the value of ∆G is +325 kJ, while ∆G equals -575 kJ for Reaction B. Which of the following best compares how these reactions affect the organism?

Reaction A creates equilibrium, while Reaction B displaces equilibrium.
Reaction A decreases entropy, while Reaction B increases entropy.
Reaction A occurs spontaneously, while Reaction B is non-spontaneous.
Reaction A releases energy, while Reaction B absorbs energy.

Answer 13

The organization of organisms has increased in complexity throughout time. In light of this trend, which of the following is true?
As organisms increase in complexity, the entropy in the surrounding universe correspondingly increases.
Each organism is considered a closed system, and therefore increased organism complexity has no relationship to the laws of Thermodynamics.
Organisms increase in complexity to maintain homeostasis with the decrease in entropy of the surrounding universe.
The increase in organism complexity is a function of evolution, not thermodynamics.

Pretty Much

Answer 16

sorry, no idea..

Answer 17

Three different organisms of the same body mass were placed in a laboratory setting and exposed to a range of temperatures. Scientists measured the metabolic rate of each organism at each temperature. The results are presented in the following graphs.

Figure presents three graphs, each measuring the metabolic rate of a different organism over a temperature range of 0 to 60 degrees celcius. For Organism A, the metabolic rate is 0 mL oxygen per hour at 0 degrees celcius and increases proportionally with temperature. For Organism B, the metabolic rate is approximately 7 mL oxygen per hour at 0 degrees celcius, and increases proportionally with increasing temperature. For Organism C:, the metabolic rate is approximately 10 mL oxygen per hour at 0 degrees celcius, drops slightly as temperature increases to a low of 5 mL oxygen per hour at about 35 degrees celcius, and then increases slightly to about 8 mL oxygen per hour at 60 degrees celcius.

Question 18 (Multiple Choice Worth 2 points)

(03.01 HC)A biochemical reaction has the following values relating to energy flow:

T = 473K
∆S = 1.11 kJ/K
∆H = -704kJ

Which of the following statements is true about this reaction?
The reaction is always spontaneous. The reaction is never spontaneous. The reaction is spontaneous only when ATP is coupled to it. The reaction is spontaneous only when the temperature is above 0°K.

Question 19 (Essay Worth 5 points)

(3.01 HC)Within an organism, both spontaneous and non-spontaneous chemical reactions take place to meet the needs of the organism. Describe how an organism would be affected, in terms of free energy and entropy, if only spontaneous reactions occurred.


Question 20 (Essay Worth 5 points)

(3.04 HC)During the process of cellular respiration, one molecule of glucose is capable of producing up to 32 molecules of ATP. Explain the mechanism by which ATP is produced by ATP synthase. Be sure your answer describes the structural features involved in this process.
