Answer:
only one substrate could be converted to product by the enzyme
Explanation:
If an enzyme obeys the lock and key model, it then follows that the design of the enzyme is unique to a particular substrate.
Just as only the correct key can effectively fit into a lock, only the appropriate substrate whose design matches that of the enzyme can fit into the enzyme.
Owing to the lock and key model of enzyme activity, only one enzyme could interact with a substrate to yield particular product.
Answer:
286 minutes
Explanation:
Given the content of fat in a meal= 53g
the content of protien in a meal= 38g
the content of carbohydrate in a meal= 152g
Also given that fuel value of protien = 17 KJ/g
the fuel value of fat = 38 KJ/g
the fuel value of carbohydrate = 17 KJ/g
Now to burn all the molecules the energy recquired is content of molecule times the fuel value.
the energy recquired to burn fat = 
the energy recquired to burn protien = 
the energy recquired to burn carbohydrate =
The total energy=2014+646+2584=5244KJ
The energy spent on swimming is 1100KJ/hour
for 1 hour 1100 KJ are spent
to spend 5244 KJ of energy the time taken is = 
=4.76hours
We know 1 hour=60 minutes
The total time = 
Parsec is a unit of distance (as stated 1 Parsec = 3.26 light years, wihch is 3.26 times the distance run by light in one year).
That distance is:
1 parsec = 3.26 mi× 186,000 mi/s × 3600 s/h × 24 h/day × 365 day/ year × 1 year = 19,122,168,960,000.mi.
So, the question of <span>how many parsecs it takes for light to reach Mars from Earth does not make sense because parsecs is not a unit of time.

</span><span>You can calculate how many parsecs is equivalent to the distance between Mars and Earth, 60,000,000 km. For this you can first calculate the equivalence of which you do in this way:

</span><span>
</span><span>60,000,000 km × 0,621 mi/km × 1 parsec / ( 19,122,168,960,000 mi) = 1.94E-6 parsecs.
