Structure And Hydrolysis of ATP

Question 1

What is ATP(Adenosine triphosphate)

Answer 1

is the cells energy shuttle
and it provides energy for Cellular functions

Question 2

Endergonic reactions

Answer 2

when 🔺️G is positive the reaction is not spontaneous.
eg: Glutamic acid + Ammonia(NH3)➡️ Glutamine(GluNH2)
🔺️G=+3.4kcal/mol

Question 3

Exergonic reaction

Answer 3

when 🔺️G is negative the reaction is spontaneous

eg: ATP+ H2O➡️ADP+ Pi

🔺️G=+7.3kcal/mol

Question 4

Coupled reactions

Answer 4

Overall 🔺️G is negative together reactions are spontaneous
🔺️G=-3.9 kcal/mol

Question 5

How does ATP WORK?

Answer 5

it drives Endergonic reactions by phosphorylation, transferring a phosphate to other molecules

Question 6

The three types of cellular work Are?

Answer 6

powered by hydrolysis of ATP
a)Mechanical work: ATP phosphorylates motor proteins
b) Transport work: ATP phosphorylates transport proteins

c) Chemical work: ATP phosphorylates key reactants
