Suppose that 1 mL of an enzyme solution can completely catalyze 10 mL of substrate in 8 minutes. Now suppose that you change the amount of enzyme, the amount of substrate, or add another substance to the mixture. How would each type of change affect the reaction rate

Increase in enzyme concentration( >1 mL) with same (10 mL) of substrate.

If we increase the enzyme concentration with the same amount of substrate the reaction will be completed in less time than 8 minutes because more active sites would be converting reactants to products.

Decrease in enzyme concentration( <1 mL) with same (10 mL) of substrate.

If we decrease the enzyme concentration with the same amount of substrate the reaction will be completed in more time than 8 minutes due to less availability of enzymes catalytic sites..

Increase in substrate concentration (>10 mL) with the same amount of enzyme (1 mL).

If we increase the substrate concentration with same amount of enzyme the reaction would take more time than 8 minutes.

Decrease in substrate concentration (<10 mL) with the same amount of enzyme (1 mL).

If we decrease the substrate concentration with same amount of enzyme the reaction would take less time than 8 minutes.

Add another substance such as inhibitor to the mixture.

If we add inhibitor to the mixture it would temporarily or permanently block the active site of enzymes and reaction would be either take more time to be completed or it would never be completed.

answer:

the answer is 6 valence electrons.

explanation:

valence is the # of electrons on the outer most shell of an atom.

oxygen has 6.

although, the valency of oxygen is 2, because it only needs to make 2 covalent bonds, or gain 2 electrons, to achieve the stable octet configuration of a noble gas.

that's it!

if you need further assistance, let me know: )

most historians agree that gabriel mouton, the vicar of st. paul’s church in lyons, france, is the “founding father” of the metric system. he proposed a decimal system of measurement in 1670. mouton based it on the length of one minute of arc of a great circle of the earth (now called a nautical mile, 1852 meters). he also proposed the swing-length of a pendulum with a frequency of one beat per second as the unit of length (about 25 cm). a pendulum beating with this length would have been fairly easy to produce, thus facilitating the widespread distribution of uniform standards. over the years, his work was revised, improved, and extended by a number of french scientists.

the political sponsor of weights and measures reform in the french revolutionary national assembly was the bishop of autun, better known as talleyrand. under his auspices, the french academy appointed several committees to carry out the work of developing a usable system of weights and measures for france. one of the committees recommended a decimalized measurement system based upon a length equal to one ten-millionth of the length of a quadrant of the earth’s meridian (i.e., one ten-millionth of the distance between the equator and the north pole).
