ATP

Question 1

What are the components that make up a single ATP unit?

Answer 1

adenine, which bonds to a ribose sugar via a glycosidic bond. ribose bonds to a phosphate via a phosphoester bond.

Question 2

In a catabolic reaction, such as glycolysis, is ATP used or produced?

Answer 2

Catabolism reactions break down larger compounds into multiple smaller compounds.
Catabolic reactions are involved with making ATP via the breaking of its phosphoanhydride bonds.

Question 3

In an anabolic reaction, such as the assembly of a protein chain from individual amino acids, is ATP used or produced?

Answer 3

Anabolic reactions build larger compounds from multiple smaller compounds.
Anabolic reactions use ATP as connecting compounds (forming bonds) requires energy.

Question 4

How much energy is released from ATP when one of its phosphoanhydride bonds is broken and it becomes ADP? What is this energy used for?

Answer 4

When one of the phosphoanhydride bonds of ATP is broken, a phosphate (Pi) is released along with 7.3 Kcal/mole of energy.
The energy released is used to power cellular processes that keep the cell functioning and alive.

Question 5

What would happen if our cells stopped making ATP?

Answer 5

If our cells stopped making ATP, the cell would start to die. After enough cells die, organs would begin to fail and the individual would die.
