[Cellular Respiration]
Excess glucose in your blood is stored in your liver as glycogen.
How do your body "know" when to convert glucose to glycogen and glycogen back to glucose???

OH YEAH...One part, i SORT OF know is that cellular respiration occurs in your body, producing more ATP, etc.
is that also correct?

THANKS!

Question: Goldbach's conjecture states that every even natural number except 2 is the sum of two prime numbers. For Example, 24 = 7 + 17 and 16 = 3 +13. Write each even number from 30 to 40 as the sum of two prime numbers.



LOL! I don't understand a word it says! PLZZ help! hahaha.
