Deoxyribonucleic acid and ribonucleic acid
Answer: Explain why two different enzymes are needed for the synthesis of glycogen from glucose phosphate. This is because enzymes are substrate specific, in that each enzyme only catalyzes one substrate. This is because enzyme activity increases with concentration, or availability of the substrates.
Explanation:
Since it is easily calculated using a calculator, I assume you need this done in the head.
Yes, you can do that.
It takes a few words to explain this, but if you understand how this is done, it goes fast.
27=3*9
so 7263*27 = (7263 * 3) * 9
so first multiply 7263 by 3.
72*3=216, 63*3=189
so 3*7263=21789
So far so good.
Now you can multiply anything by nine by subtracting from the right neighbour, starting from the right.
For example, 27*9. the right neighbour of 7 is 0, borrow 1, so 10-7=3
the right neighbour of 2 is 7, but we borrowed 1, so 6. 6-2=4
At the beginning of the number 27, we add a zero which we subtract from the right neighbour 2 to get 2.
So 27*9=243.
Now for 21789, we have successively
(10)-9=1
8-8=0 (9 was borrowed to become 8)
8-7=1
7-1=6
(11)-2=9
and finally
1 -0 = 1 (2 was borrowed to become 1)
So the final answer is 196101
