Question

in each of the three systems, determine the state of entropy (low or high) when comparing the first and second: i. the instant that a perfume bottle is sprayed compared with 30 seconds later, ii. a kids room after it hasnt been cleaned for a week, and iii. a living cell compared with a dead cell.

i. low, ii. high, iii. low
i. low, ii. high, iii. high
i. high, ii. low, iii. high
i. high, ii. low, iii. low
none of these answer choices are correct.

question 8
the energy released by the hydrolysis of atp is____.
primarily stored between the alpha and beta phosphates
equal to -57 kcal/mol
harnessed as heat energy by the cell to perform work
providing energy to coupled reactions
none of these answer choices are correct.

question 9
which of the following molecules is likely to have the most potential energy?
maltose
2 atp
glucose
adp
none of these answer choices are correct.

Explanation:

Question 7

Entropy is a measure of disorder. When a perfume bottle is first sprayed, the perfume molecules are in a more ordered state (low entropy), and 30 seconds later, they spread out and become more disordered (high entropy). A kids - room that hasn't been cleaned for a week is more disordered (high entropy). A living cell has more order in its biochemical processes compared to a dead cell which has broken - down structures and processes (low entropy in living, high in dead).

The hydrolysis of ATP releases energy that is used by the cell to drive coupled reactions. The energy is not primarily stored between the alpha and beta phosphates, the energy released is not - 57 kcal/mol, and it is not harnessed mainly as heat energy for work.

ATP stores a significant amount of energy in its phosphate - bonds. Two ATP molecules have more potential energy than a single glucose molecule, maltose (a disaccharide), or ADP.

Answer:

i. low, ii. high, iii. high
